441!!![=OpenSceneGraph=] 1.2 release introduces Windows 64bit and AIX support, COLLADA support, processor affinity and texture atlas builder.
442
443PERTHSHIRE, Scotland - 12th September 2006  - [=OpenSceneGraph=] Professional Services announces the release of [=OpenSceneGraph=] 1.2, the industry's leading open source scene graph technology, designed to accelerate application development and improve 3D graphics performance. [=OpenSceneGraph=] 1.2, written entirely in Standard C++ and built upon [=OpenGL=], offers developers working in the visual simulation, game development, virtual reality, scientific visualization and modeling markets a real time visualization tool which rivals established commercial scene graph toolkits in functionality and performance. [=OpenSceneGraph=] 1.2 runs on all Microsoft Windows platforms, Apple OS/X, GNU/Linux, IRIX, Solaris, HP-UX, AIX and [=FreeBSD=] operating systems.
444
445The [=OpenSceneGraph=]-1.2 release introduces:
446
447* Support for Windows 64 bit build, allowing Windows programmers to take advantage of greater scalability previously only available to [=OpenSceneGraph=] users under Linux, IRIX, Solaris, [=FreeBSD=] and OSX.
448* Support for IBM's AIX operating system, bringing the total number of supported operating systems to 8.
449* COLLADA plugin support for both the reading and writing of COLLADA 1.4 .dae files.  COLLADA is the new industry standard data asset exchange format that is now supported by a range of 3D modelling packages and provides a unified art path route to and from the [=OpenSceneGraph=].
450* Processor affinity support allowing application to lock cull-draw and database processes to specific processors, thereby avoiding cache coherancy problems associated with processes moving from processor to processor.
451* A Texture Atlas builder has been added to the database optimization classes, allowing either manual or automated setting up of texture atlas.  Using texture atlas can improve performance by reducing the number of state changes required to render a scene, and by allowing databases to batched in large groups of geometry, in a form that better suits modern graphics arhitectures.
452* GPU timing stats have been added to the viewer class, provided the time taken to process allow drawing operations down on the GPU for the previous frame.  Coupled with the existing timing of CPU update, cull and draw dispatch the stats reporting now provides the end user with a clearer idea of whether their application is CPU or GPU limited and server as a better guide to performance optimization work.
453* A range of bug fixes and API refinements.
454
455The [=OpenSceneGraph=]-1.2 release is the culmination of 7 years development, with contributions from 208 developers from around the world.  The user base is composed of a wide range of industry and academic users with over 1400 developers subscribed to the projects public support mailing list.

566BETA releases
567
56825th May 2005 - OpenSceneGraph-0.9.9
569
570>>> OpenGL Shading Language integrated into core, Introspection, movies, particle effects and much more... 
571
572Introduction to the OpenSceneGraph:
573
574The OpenSceneGraph is an Open Source, high performance real-time graphics toolkit, written for developers of vis-sim applications, virtual reality, scientific visualisation, education through to games.  The toolkit is based on OpenGL and Standard C++ and most portable toolkit of its kind, supporting Windows, Linux, OSX, Irix, Solaris, FreeBSD and HP-UX and Aix, including 64 bit support on Windows, Linux, OSX, Irix and Solaris.  OpenGL version from 1.1 through to 2.0 are all seemlessly supported, including many of the latest extensions.  The OpenSceneGraph is now firmly established as one of the worlds most popular scene graph technologies, and is used and developed by community of over a thousand developers.
575   
576The OpenSceneGraph 0.9.9 release:
577   
578The latest release of the OpenSceneGraph, 0.9.9, is the culmination of 7 years development and is the final milestone before reaching 1.0. All core features for 1.0 are now in place and ready for deployment.  Since the development driven is by technical convergence rather than usual marketing forces, even the beta releases of the OpenSceneGraph are already mature enough for major industry players to have adopted it for their own application development, with many companies already releasing products based on top of the OpenSceneGraph.
579   
580The 0.9.9 release includes many minor API refinements, bug fixes and optimizations, but also major new features including tight integration of OpenGL Shading Language support directly into the core osg library, new reflection/introspection support, new particle effects, movie support and DXF import.  Details follow:
581       
582OpenGL Shader Language support:
583   
584OpenGL Shading Language (GLSL) support has been moved from the osgGL2 node kit directly into the core osg library.  This move also involved refactoring the handling of state so that it now specifically supports GLSL Program, Shaders and Uniforms in a convenient and flexible way. State sorting and lazy state updating are now applied to both Program and Uniforms to maximize performance throughput.  The work was spearheaded by 3Dlabs engineer Mike Weiblen, collaborating with Robert Osfield with contributions from the community.
585       
586Introspection support:
587   
588The new osgIntrospection and associated library wrappers provides support for full API reflection/introspection.  That facilitates integration of the OpenSceneGraph with other programming languages, development of generic editors of scene graph attributes, general purpose serialization of scene graph objects such as for reading and writing to disk, or across local networks to support systems such as graphics clusters.  The osgIntrospection is designed
589to be non-intrusive, allowing 3rd Party libraries to be wrapped without these libraries needing to have explicit introspection support added into them.  The-non intrusive approach also keeps introspection support a separate module which only needs to be loaded if you require it, this leaves the core libraries light-weight and focused on the their particular tasks.  osgIntrospection is the inspired work of Marco Jez.  Thanks also go to ANU Viz Lab for graciously funding Robert Osfield's contribution to this sub-project.
590
591Better support for Apple native Windowing:
592
593Thanks to new support for AGL and CGL in OpenProducer, all OpenSceneGraph/osgProducer-based examples and application will run straight out of the box under OSX native AGL or CGL Windowing. This allows better integration of OpenSceneGraph applications with OSX, access to faster and up to date OpenGL drivers.
594   
595Support for latest OpenGL extensions:
596   
597Support for the Non power of two texture feature of OpenGL 2.0 has been added
598to all the core texture classes.  Also to facilate high resolution video streaming, OpenGL  Pixel Buffer Objects are now supported.  Support for blend equation and logic op have also been added.
599   
600Terrain generation and rendering enhancements:
601   
602The osgTerrain library, for generating whole earth, geospecific paged databases, has been enhanced with support for alpha source textures and multiple texture layers.  The new multiple texture layers support can be controlled at runtime via the new osgFX::osgFX MultiTextureControl node, which provides a convenient means for blending between the different layers at run-time.  Multiple textures layers can be very useful for mixing topographical maps with satellite/aerial photography.
603       
604Particle Effects:
605   
606To make it easier to add particle effects to your application a new osgParticle::ParticleEffects node has been written, with five concrete implementations of SmokeEffect, FireEffect, ExplosionEffect and ExplosionDebrisEffect which you can create, adjust and add to your scene graphs.
607   
608DXF and Movie plugins:
609   
610A new DXF plugin has been added for reading .dxf files.  Movie support has also been enhanced with integration of the OpenSceneGraph with Xine-lib via the xine plugin, this allows you to add movie content into your applications, including DVD's and streamed across the LAN, thanks to Xine-libs inbuilt streaming support.
611   
612Application and examples:
613   
614To facilitate faster builds and a logical division between applications that come with the OpenSceneGraph, the original example directory has now been split into two, with the new applications/ directory now comprising osgviewer, osgconv, osgarchive, osgversion and osgdem.  The Makefiles now build by default only the applications directory, thus avoiding the cost of recompiling the 74 example programs.  Examples can still be compiled by run make COMPILE_EXAMPLES=yes, or setting COMPILE_EXAMPLE=yes as an env var or in a custom dependencies file.
615   
616There are eight new examples, osgblendequation and osglogicop demonstrate the new osg::BlendEquation and osg::LogicOp state attributes,  osgGLUTkeyboardmouse and osgGLUTsimple are GLUT based examples, osgslice does some image reading of rendered slices, osgparticleeffects demonstrates the new osgParticle::ParticleEffects.
617   
618osgpbuffer also example now uses Producer's pbuffer support making it portable across platforms and much cleaner.
619   
620API refinements, bug fixes and performance improvements:
621   
622There have been many bug fixes, a number of performance improvements and API cleanups that have occured throughout the 0.9.8 - 0.9.9, too many separate items to enumerate here.  Together with the above new features they all go to making the OpenSceneGraph-0.9.9 the most robust, high performance and feature rich version so far, and sets the stage for the upcoming 1.0.

65126th November 2004 - OpenSceneGraph-0.9.8
652
653    >>> Support for database archives, improved pager, 3d compressed textures
654
655    Release 0.9.8 reflects a continuation of the prior committment to release
656    often, arriving only two short months after 0.9.7.  This contrasts sharply
657    to the long period between 0.9.6-2 and 0.9.7.  The following set of
658    improvements and features are part of the 0.9.8 release.
659
660    The osgDB Pager has been Improved to provide better multi-processor
661    stability and constant frame rate peformance.
662
663    Reference documentation has been taken out of the main distribution and
664    placed on the public website.  The documentation is also now completely
665    built with Doxygen.
666   
667    New Plugins added or modified this release:
668
669        o STL    - This plugin provides OSG with the capability to import
670                   Stereolithography files, commonly used in the CAD
671                   markets.

677                   large file (greater than 2 GB) support.
678       
679        o OBJ    - The existing obj plugin has been re-written for clean up.
680   
681
682    New support for 3d texture compression using the
683    GL_NV_texture_compression_vtc extension has been added, providing an
684    improvement on the S3TC compression techniques.
685   
686    The OSG Spelling Bee is making its mark in this release, with submissions
687    by the community to correct spelling and typo errors throughout the osg,
688    osgDB and osgUtil libraries.
689   
690    osgDB::ReaderWriter and osgDB::Registry have been refactored to allow
691    multi-threading of database reading and writing.       
692   
693    The NodeTrackManipulator has been improved.   
694   
695    Several general bug fixes have been fixed.

709
71018th August 2004 - OpenSceneGraph-0.9.7-2
711
712    Build fixes for VisualStudio6.0. 
713    Fixes for osgFX registry support.
714    Fixes to osg::Image::flipVertical() adding support for mipmaps and
715    compressed textures. 
716    DDS plugin now can vertically flip images by using "dds_flip" Options string.
717    Added support in osgTerrain for reading imagery with color tables.
718   
719
7209th August 2004 - OpenSceneGraph-0.9.7
721
722    >>> support for and generation of large scale geospatial databases,
723    >>> support for movies and examples of shadows and volume rendering.
724   
725    The 0.9.7 encompasses many improvements, bug fixes, new examples and
726    significant new functionality, the most notable of which is a new
727    osgTerrain library for generation of large scale geospatial databases.
728   
729    The new osgTerrain library and associated osgdem utility program
730    allows users to use moziacs of geospatial imagery and digital elevation
731    maps to generate a complete paged database which can be used with
732    standard OSG viewers, and users programs. By utilising GDAL to load the
733    imagery and DEM's a wide range of geospatial formats are supported.   
734     
735    The TerraPage plugin has also been rewritten ontop of the OSG's
736    osg::PagedLOD and osgDB::DatabasePager which provides support for the
737    tile fallback mechanism to ensure that no holes or cracks appear in the
738    databases being roamed, and to achieve constant frame rate via load
739    balancing mechanisms with osgDB::DatabasePager.
740   
741    The osgDB::DatabasePager has been further improved to provide more
742    configurable load balancing which allows application developers to achieve
743    constant frame rates when using paged databases.
744   
745    Double Vec & Matrix classes & CoordinateSystemNode/EllipsoidModel class
746    have been introduced to better support browsing of large scale databases,
747    and to provide a mechanism for tracking the local up orientation when
748    roaming whole earth databases.
749   
750    osgUtil has been enhanced with:
751     - an improved triangle tipper class (osgUtil::TriStipVisitor),
752     - a new simplifier (osgUtil::Simplifer) for reducing triangle density of
753       osg::Geometry leaves (utilised by osgTerrain to provide simplification
754       of terrain tiles),
755     - improved and more configurable optimizer (osgUtil::Optimizer),
756     - a new utility class for compiling and releasing OpenGL objects
757      (osgUtil::GLObjectVisitor) replaces the previous and more limited
758       DisplayListVisitor.
759   
760    All the osgGA::MatrxManipulator's (used for camera manipulator etc) have
761    been revamped with usage of doubles internally, and with tracking of the
762    current CoordinateSystem if one is active, to be better support whole
763    earth databases.  All the MatrixManipulators have been extend to allow
764    the setting of a user defined home position.  Two new manipulators have
765    been introduced osgGA::TerrainManipulator, for roaming whole earth/terrain
766    databases, and osgGA::TrackerManipulator which allows the camera to be
767    attached to a node in the scene graph.
768
769    Movie support under Linux and OSX via libMpeg3 and Quicktime respectively,
770    which extend the new osg::ImageStream base class which allows application
771    developers access to playing, pausing and rewinding movies.
772
773    The conversion utility osgconv has been extended to allow compression of
774    textures and mipmap generation during conversion when writing to the native
775    .ive binary format.  Texture compression and pre computer mipmaps enable
776    faster loading of databases and lower utilisation of memory resources.
777
778    Write support added to JPG plugin.
779   
780    Write + 3D texture support added to DDS plugin.
781   
782    Pseudo loaders .trans, .rot and .scale have been added.
783   
784    Updated LWO, AC3D, BMP, IVE and FLT loaders.
785   
786    osg::TexGenNode has been added to provide a mechanism for positioning
787    OpenGL's texture coordinate generation planes.
788
789    Fourteen new examples have been added:
790   
791        osgdem            a utility for creating large scale geospatial paged
792                          database
793

795                          geometry for paged in imagery
796
797        osgbluemarble     an example of how to build PagedLOD database for
798                          paging imagery

806                          shadow textures.
807
808        osgsimplifier     an example of how to use the new osgUtil::Simplifier.
809
810        osgspacewarp      an example of how to create a special effect that
811                          depends upon tracking the modelview matrix.
812
813        osgdistortion     an example of how to use prerendering of a texture to
814                          create a distortion effect.
815
816        osgsimple         a bare bones example of how to create a simple viewer
817                          using a Windowing toolkit, in this example using
818                          Producer, but is written so the example could easily
819                          be modified to work with other Windowing toolkit.
820
821        osgkeyboardmouse  adding to keyboard and mouse functionality on the
822                          osgsimple base.
823
824        osgsimplepager    adding database paging support to the osgsimple
825                          example.
826   
827        osgmovie          an example which creates a quad to render a loaded
828                          movie file with - requires the LibMpeg3 (Linux) or
829                          Quicktime (OSX) plugin to work.
830       
831        osgvolume         an example that reads a stack of 2d images to create
832                          a 3D texture, and creates a scene graph using
833                          standard OSG components (osg::ClipNode,
834                          osg::TexGenNode, osg::Billboard and
835                          osg::TexEnvCombine) to create a per per lit volume.
836
837   
838    Wrapping up the complete 0.9.7 release is a wide range of smaller features
839    enhancement and many bug fixes.
840
841
8422nd October 2003 - OpenSceneGraph-0.9.6-2
843
844    >>> osgFX Special Effects nodekit (for bumping mapping & cartoon effects etc), support for double Matrix traversals,
845    >>> improved build support, thread safety and robustness.
846   
847    The new osgFX nodekit, written by Marco Jez, adds a set of decorator
848    nodes that add can be conveniently added above subgraphs in your scene
849    to add special a range of special rendering effects.  Effects include
850    AnisotopicLight, BumpMapping, Scribe, Specular Highlights and Cartoon
851    rendering.
852   
853    Support for double Matrices has been added with the new Matrixd class,
854    and complimented by the a Matrixf class.  The original Matrix class is
855    now a typedef which can be set to either Matrixf or Matrixd (which is
856    now the default),  When the Matrix typedef is set to Matrixd and the OSG and
857    dependent apps are recompiled all internal operations such a cull traversals
858    will now be double with double matrices which much improved numerical
859    precision, making it ideal for datasets where a large values are contained
860    with transforms in the scene graph (such as with whole earth databases),
861    and when a transforms are nested which creates requires concatenation of
862    a number of matrices to get the final model view matrices. 
863   
864    The osgGA::MatrixManipulators (which are used to control the camera
865    position) and osgProducer/OpenProducer have been moved across to using
866    exclusively double Matrices.  This has been done to improve numerical
867    precision when computing camera positions, whilst having little impact
868    on performance since camera operations are only done a small number of
869    times per frame.
870   
871    osg::Quat now supports doubles by default, but also allows users to select
872    float version osg::Quat simply by changing the osg::Quat::value_type typedef.
873   
874    Work has been on OpenThreads and OpenProducer, in particular to improve
875    thread safety and robustness on the Win32 platform.  Reported crashes
876    on exit from osgProducer::Viewer based apps, and freezes during runtime
877    have been fixed.
878   
879    Threading problems which caused crashes in recent updates of the Terrapage
880    loader have also been fixed, and additional internal changes have been made
881    to improve the Terrapage loader's ability to hit constant frame rates.   
882    Support has also been added for loading light points directly from the
883    Terrapage database.
884
885    A new .iv/.wrl loader plugin, written by Vivek Rajan, at Magic Earth,
886    has been added to the distribution which uses with OpenInventor or Coin
887    to load model, converting them into OSG equivalents.  Coin has support
888    for VRML97 models, so can be used to import such models into the OSG. 
889    Since the new plugin is dependent on OpenInventor or Coin the compilation
890    is optional, but off by default. To compile this plugin under Unix, set
891    the environmental variable USE_INVENTOR or USE_COIN and recompile. 
892    Windows .dsp project file does to current exist, but should be
893    possible to add this.
894   
895    The .ive plugin has been improved with the addition of support for
896    osgSim light points, and various internal refinements to make it function
897    better on the various platforms supported by the OSG.  Note, these changes
898    mean that the .ive format has has changed and is no longer compatible
899    with previous version of .ive. It is recommend that one recreates .ive
900    for the original source via osgconv or similar to ensure consistency.
901
902    A JPEG2000 image plugin has added, written by Michael Gronager.  The new jp2
903    plugin uses the japser open source project to read and write JPEG2000 files.
904   
905    A scalar bar, and sphere segment helper classes have been added to osgSim,
906    the new osgscalarbar and osgspheresegment examples demonstrate how to use
907    these new features.
908   
909    To help handle running applications of graphics cards/drivers that exhibit
910    bugs with certain OpenGL extensions, support has been added to the GLextensions
911    code to allow extensions to be disabled via the new
912    osg::setGLExtensionDisableString(std::string) function or by setting an
913    OSG_GL_EXTENSION_DISABLE environmental variables.  Follows is an example of
914    the disable string:
915   
916        set OSG_GL_EXTENSION_DISABLE =
917             "ATI:GL_SGIS_generate_mipmap;Sun:GL_EXT_texture_filter_anisotropic:"
918
919    New examples include:
920   
921        osgforest - an example which demonstrates simple techniques for creating forests   
922        osgfxbrowser - an example which demonstrates the various osgFX Effects available   
923        osgscalabar - an example of how to set up the osgSim::ScalarBar.
924        osgspheresegment - an example of how to set up the osgSim::SphereSegement
925        osgpagelod - a very simply test program for setting up osg::PagedLOD/osgDB::DatabasePager
926   
92723rd July 2003 - OpenSceneGraph-0.9.5
928
929    >>> Support added for OpenGL2.0 shaders, native multi-threaded Database paging,
930    >>> high peformance binary format reading and writing,  .dds compressed image
931    >>> loader and ARB_fragment_program and ARB_vertex_buffer_object extensions,
932    >>> improvements to the Terrex .txp and OpenFlight .flt loaders.
933
934    The key new features of the 0.9.5 release are the new OpenGL2.0 nodekit, constant frame rate
935    database paging support,  classes,  and the new native .ive binary plugin which supports
936    both reading and writing of all core osg nodes, including inlining of compressed
937    and non-compressed imagery.
938   
939    The native database paging support, provided by the new osg::PageLOD and osgDB::DatabasePager,
940    achieves constant frame rate through threading of the database reading, and time based
941    incremental compile and delete of display lists, vertex_buffer_objects and texture objects.
942    A new TextureObjectManager class also caches a list of expired texture objects for reuse,
943    and allows new newly loading imagery to reuse expired texture objects, with the imagery
944    automatically subloaded to the reused texture objects.  This reuse happens transparently
945    and benefits other OSG usages such as the OSG's Terrapage loader.
946   
947    To provide support multi-thread operation of the OSG, such as multi-thread database paging
948    and multi-threaded, multi-window graphics enabled by OpenProducer, the OpenSceneGraph and
949    OpenProducer have now adopted the OpenThreads threading library, osgDB and osgProducer now
950    depend upon it.  OpenThreads is open source, light weight, cross platform C++ threading
951    which encapsulates the low level, platform specific threading API calls.  Currently pthreads
952    under Unix and Win32 threads under Windows are supported, with Sgi sproc threads to be
953    released very soon.  The OpenThreads project website can be found at http://openthreads.sf.net.   
954
955    The new .ive binary plugin was developed by Uni-C's VR-Center, and kindly submitted as
956    open source, adds support for binary reading and writing OSG nodes drawable and state
957    (including compressed/mipmapped) textures.  The .ive format produces a much faster
958    load times and smaller file size then native ASCII .osg format. Load times for .ive
959    files are also 10-20x faster then equivalent OpenFlight .flt and load in an already
960    optimized scene graph form making it much more suitable for paging.  Files can be
961    converted easily using the osgconv utility : osgconv myfile.flt myfile.ive
962   
963    The new osgGL2 nodekit library adds support for the OpenGL2.0 vertex ProgramObect and fragment
964    ShaderObject's recently ratified by the OpenGL ARB, . The osgGL2 uses the extension have local
965    prototypes which allow them to be compiled even in the absence of OpenGL headers that don't
966    support the GL2 extension, allowing to port to all platform, and at runtime the extensions are
967    queried for and used if available.  At time of release only 3DLabs WildcatVP series supported
968    this extension at runtime, but other graphics cards and manufactures will be releasing GL2
969    extension very soon and will be automatically supported by osgGL2. The osgGL2 was developed
970    by Mike Weiblen at 3DLabs whom have kindly submitted osgGL2 as open source and for inclusion
971    with the OSG distribution. 
972
973    The ARB_fragment_program, ARB_vertex_buffer_object and ARB_vertex_program attributes are
974    also now supported in core osg library.  The new osg::FragmentProgram state attribute
975    encapsulates the ARB_fragment_program which is supported by the recent graphics cards
976    from NVidia, ATI and 3DLabs.  Support for ARB_vertex_buffer_object and ARB_vertex_program
977    attributes have been added to the osg::Geometry class.  The ARB_vertex_buffer_object extension
978    can boost performance by as much as 50% when working on geometry bound data sets.
979
980    Two new image loaders, dds and pnm, and a 3dc point cloud have been added. The .dds plugin
981    adds support for compressed & mipped mapped imagery, making it ideal for applications where
982    large texture sizes or database paging is required. The pnm image loader reads the
983    pnm, pgm and pbm image formats. See http://netghost.narod.ru/gff/vendspec/pbm/ for details.
984
985    The Terrapage .txp plugin  been updated to include support for multi-texturing, layers and billboards
986    and includes improvements to multi-threaded pager, which has also been ported over to use OpenThreads.
987    The OpenFlight .flt plugin has also been improved and now support detail textures via multi-texturing.
988
989    TessellationHints now supported by ShapeDrawable which allow the shape primitives to be rendered
990    are vary levels of detail.
991
992    Supported has been added for auto scaling and rotating text into osgText.
993
994    Five new examples have been included in the distribution:
995   
996        osgtexturerectangle illustrates how to use the osg::TextureRectangle which encapsulates
997        the NV_texture_rectangle extension.
998       
999        osgprerendercubemap illustrates how to use pre rendering imagery to osg::TextureCubeMap
1000        for tasks such as building a environmental texture maps.
1001       
1002        slideshow3D is a presentation tool which use a scene graph to store a render set of slides, each
1003        slide containing layers which can contain bullet points, paragraph, imagery and 3d animated
1004        models - and is effectively a 3D power point. The presentations can be built separately and stored in a .osg file or created by
1005        slideshow3D via an xml file, two examples - introduction.xml and models.xml, which are included
1006        in the OpenSceneGraph-Data-0.9.5 data distribution.  slideshow3D depends upon libxml2 for parsing
1007        the xml files.
1008       
1009        osgpoints uses the osg::Point state attribute to attenuate and control point size and any points
1010        loaded by the application.  This is a useful way of visualizing point data clouds.
1011       
1012        osgdemeter is example of how to integrate the Demeter, OSG using osgProducer::Viewer as a viewer
1013        class.  This example depends upon the demeter terrain engine, which can be download from
1014        http://www.terrainengine.com.
1015
1016    Camera style convenience set and get methods to osgUtil::SceneView, consolidating
1017    previous functionality that was provided by both osg::SceneView and osg::Camara into one place.
1018    This move has made osg::Camera redundant so has it been removed to avoid confusion,
1019    usage inconsistencies and bloat of core libraries.
1020   
1021    The long time deprecated osg::GeoSet has been removed, to aid migration of old .osg datasets
1022    osgconv has a copy of GeoSet and the .osg support for it so is able to convert any remaining
1023    .osg database which contained GeoSet's.

102728th April 2003  - OpenSceneGraph-0.9.4-2
1028
1029    >>> Multi-threaded, multi-pipe support via integration with OpenProducer,
1030    >>> 64bit Linux support for Intel Intanium and AMD Opteron,
1031    >>> new osgText library with greater performance, and thread safety,
1032    >>> new DDS plug-in for compressed and non-compressed images,
1033    >>> new MD2 plug-in adds support for animate Quake character and
1034    >>> support added for NV_texture_rectangle.
1035
1036    The most significant new feature is the osgProducer library that adds
1037    tight integration with OpenProducer, providing the OpenSceneGraph with a
1038    scalable, configurable and portable framework for developing real-time
1039    and interactive graphics applications.  The scalability afforded by
1040    OpenProducer allows applications to be developed which run seamlessly
1041    on single pipe machines up to multi-pipe machines such as Sgi Onyx
1042    IR system, and Sun Zulu systems.
1043    The osgProducer/OpenProducer framework automatically handles the
1044    multi-threading of cull-draw pairs and GUI events.
1045
1046    All the example programs have been ported over from being based on
1047    GLUT to using osgProducer (osgGLUT can now be found in the bazaar
1048    section on the website). The move to osgProducer allows all the examples
1049    to scale from running on laptops up to multiple CPU and graphics pipe systems.
1050    The configuration of threading and multiple camera views can all be done
1051    via ASCII configuration files, no need to recompile.  A number of
1052    new examples have also been added or revamped, bringing the total to 42.
1053
1054    Also in the theme of increasing scalability there is support for 64bit Linux for both
1055    IA64 (Intel Itanium) and x86-64 (AMD Opteron) which compliments the existing
1056    support for Solaris and IRIX 64 bit compilation.  64 bit supports allows
1057    the use of very large data sets, and potential performance improvements.
1058
1059    To help support development teams working with multiple build configuration,
1060    the makefile system has been extended to allow multiple build targets to be
1061    built from one source code base.  All makefiles are also now named GNUmakefile
1062    which ensures that they are only run by gmake to avoid an confusion on system
1063    where gmake isn't the default make tool.
1064
1065    A completely new osgText implemention has been developed which is simpler
1066    to use, faster, and thread safe.  Support for high quality true type fonts
1067    has now been moved to a freetype plug-in which is dynamically loaded on demand,
1068    with the core osgText library providing a default font when the plug-in is
1069    unavailable.  Moving the freetype dependency out of the osgText library makes
1070    it just dependant on OpenGL and Standard C++ like the rest of the core libraries,
1071    allowing osgText to compile by default on all platforms.
1072
1073    Improved thread safety has also been achieved in the core osg and osgUtil libraries
1074    making work on multiple CPU/multi-pipe systems robust and with improved performance.
1075
1076    Two new plug-ins have been added, for loading DDS and MD2 data formats. The DDS plug-in
1077    is for loading compressed and non-compressed images.  The MD2 plug-in loads Quake
1078    animated characters.
1079   
1080    osg::TextureRectangle class has been added, which encapsulates the
1081    NV_texture_rectangle and EXT_texture_rectangle extensions.  This is particularly
1082    useful for render to texture algorithms, and dynamic paging of images such as for
1083    rendering video streams.
1084
1085    Support for automatic subloading of osg::Texture2D textures has been added
1086    so that when image data is updated the corresponding OpenGL texture is
1087    automatically updated - no need for callbacks.  Also added to the osg::Texture
1088    classes is the option of automatic unref'ing of texture image data once the data has
1089    been download to all active OpenGL graphics contexts.
1090   
1091    A new osgUtil::DelaunayTriangulator utility class has been added.  This is ideal for
1092    creating optimal triangular meshes from unconnected data points.
1093
1094    Two new classes, osg::ArgumentParser and osg::ApplicationUsage, have been introduced
1095    to convineiently and robustly parse command line arguments and
1096    report command line usage, environmental variables and keyboard and mouse bindings
1097    used by applications.  Running any of the examples with -h or --help will report
1098    full details example usage.  Keyboard and Mouse bindings usage is now also available as
1099    a HUD on all examples, simply press 'h' while the app is running to
1100    bring up help.
1101
1102    A database cache in the osgDB library has been added, along with a clean up
1103    of memory management in the OpenFlight loader, make development of
1104    dynamic paging of databases easier and more robust.
1105   
1106    Support for early abort of rendering has been added, which is useful for
1107    interactive applications which occasionally have rendering that takes that long
1108    enough (i.e.several seconds) that end users may wish to abort during the drawing.
1109
1110    There have also been many general API improvements and bug fixes, too many to enumerate,
1111    but all go to solidify the quality of the scene graph and its accompanying libraries. 
1112   
1113    The combination of new features, robustness and scalability mark this release as a
1114    significant step towards 1.0.

1122    >>> DirectD .x model loader, and integration with OpenProducer for
1123    >>> multi-threaded, multi-window/pipe rendering.
1124
1125    Added osgProducer library which integrates the OpenSceneGraph seemlessly
1126    with OpenProducer to provide runtime configurable management of windows
1127    and multipipe graphic systems.  The osgproducer demo illustrate how
1128    developers can write applications very simply that harness the power
1129    of the OpenProducer and OpenSceneGraph in an extremely flexible way.
1130    OpenProducer can be downloaded from:
1131    http://www.andesengineering.com/BlueMarbleViewer/producer_install.html
1132
1133    Support added for dynamic paging of Terrage databases, the required
1134    multi-threading is set up by defult.  All the end user application need
1135    to do is load the database and the paging then happens automatically -
1136    without any need for intervention by the users application.
1137
1138    Addition of osgSim which is NodeKit designed for visual simulation
1139    market, currently features high fidelity light points support.  Light
1140    point sectors, blink sequences and groups, and light point fading are
1141    all supported.
1142
1143    From Brede Johansen, support added for the ARB VertexProgram extension
1144    with osgvertexprogram demo showing reflection and refraction in action, and
1145    osgpbuffer demo for Win32.

1154    New osglogo demo - features anti-aliased TrueType text and animation.
1155   
1156    The app phase of operations on the scene graph has been renamed
1157    the update phase to make its function clearer. The main phases are now
1158    named now does update, cull, draw.  The AppVisitor, set/getAppCallback etc
1159    have be renamed UpdateVisitor, set/getUpdateCallback etc.
1160
1161    Removed the osg/ManagerManger and associated #define osgNew's, this has
1162    been done to simplify users code and to solve the lack of thread safety
1163    that was causing problems with the MemoryManager.
1164   
1165    Support added for reading and writing of callbacks in the .osg format.
1166   
1167    Support added for reading and writing of osg::Shapes in the .osg format.
1168
1169    Support added for reading OpenFlight comment records into osg::Node description
1170    fields.

1178
1179    >>> New AC3D and GEO loaders, new Shape primitives, improved OpenFlight support.
1180
1181    From Geoff Michel, AC3D .wc and Carbon Graphics GEO .geo loaders.
1182
1183    Support for multi-texturing added to OpenFlight loader.
1184   
1185    LOD has been revamped to allow independent min and max ranges for
1186    each LOD child, bringing it inline with the OpenFlight style LOD
1187    representation.
1188
1189    Switch has been revamped to allow independent switching on or off of
1190    each Switch child, bringing it inline with the OpenFlight style Switch
1191    representation.
1192
1193    New osg::Shape geometry primitives added which allow the specification
1194    of geometry in a form that can accelerate collision detection, and as
1195    a way of specifying the geometry to tessellate.  Shapes include
1196    Sphere, Oriented Box, Cone, Cylinder, Grid, TriangleMesh, ConvexHull
1197    and CompositeShape which allows the storage of a hierarchy of shapes.
1198   
1199    Geometry has been extended to all per primitive bindings and
1200    per primitive set bindings of attributes, and indexing of attributes
1201    with the same or different index lists for each attribute list.
1202
1203    From Macro Jez, new cubemap helper classes.
1204

1220        Drawable::drawImmediateMode(..) -> drawImplementation(..) const
1221        Drawable::DrawCallback::drawImmediateMode(..) -> drawImplementation(..) const
1222   
1223
122430th August 2002 - OpenSceneGraph-0.9.1.tar.gz
1225
1226    >>> Support added for 1D & 3D textures, texture env combiners, secondary color and fog coords, DOFTransform and Sequence nodes. Inventor/VRML and LWO2 loaders added and the a port HP-UX!
1227
1228    Despite only 6 weeks passing between 0.9.0 and this latest 0.9.1 release
1229    there has been a number of significant new features, API clean ups and
1230    bug fixes.  Follows is a quick run through the key improvements.
1231
1232    Addition of osg::Texture1D, Texture2D & Texture3D classes, Texture2D replaces
1233    the original osg::Texture, which has now become a pure virtual base class. All
1234    Texture classes, including TextureCubeMap are derived from this base class..
1235   
1236    New osgtexture1D and osgtexture3D demos demonstrate the new texture classes in
1237    action.
1238   
1239    The build system has been updated to support HP-UX.  This adds one of the last
1240    remaining mainstream platforms supported.
1241
1242    A new Inventor/VRML1.0 loader was added.  The inventor format has been requested
1243    on numerous occasions, so this is a welcome addition.
1244   
1245    Support added to lwo plugin for loading the new lwo2 format.
1246
1247    osg::TexEnvCombine implemented texture_env_combine and texture_env_crossbar
1248    and texture_env_dot3 extensions.
1249
1250    osg::TexEnv texture_env_add added.
1251
1252    A osg::Sequence node has finally been implemented.  It is accompanied by a
1253    demo, osgsequence.
1254
1255    osg::DOFTransformNode implemented.
1256
1257    Support for OpenFlight15.7 added, DOFTransforms and general enhancements and
1258    bug fixes.
1259
1260    New PROTECTED mode for protecting local state mode and attributes from be
1261    overridden from state above it in the scene graph.
1262   
1263    Support for fog coord and secondary colors extensions added to osg::Geometry.
1264
1265    osg::Billboard has been improved to allow rotations around all axes, as well
1266    as point rotations.  Check osgbillboard for a new improved demo.
1267
1268    The osglight example has been improved by utilizing AnimationPath and
1269    PositionAttitudeTransform to keep light sources in motion.
1270
1271    osg::AnimationPath improved, now allowing swing and looping behavior and
1272    with two new app callbacks which can update PositionAttitudeTransform
1273    and MatrixTransform respectively.
1274   
1275    Support for writing osg::Image's to .rgb format added.
1276
1277    To keep the overall API clean, and the following items have been
1278    renamed and deprecated parts of the API have been removed:
1279
1280    Renamed classes:
1281
1282            EarthSky        -> ClearNode
1283            Transparency    -> BlendFunc
1284            Texture         -> Texture2D  (old style subload parameters removed)
1285
1286    Method's changed
1287
1288            Matrix          -> makeRotate(..) euler angles parameters generalized.
1289            Quat            -> makeRotate(..) euler angles parameters generalized.
1290
1291            BoundingBox     -> isValid() renamed valid()
1292            BoundingSphere  -> isValid() renamed valid()
1293
1294            StateAttribute  -> OVERRIDE_OFF & OVERRIDE_ON which were short hand
1295                               versions of OVERRIDE | OFF and OVERRIDE | ON
1296                               removed, as the meaning of the bitmask was
1297                               often confused by the short hand notation.
1298
1299
1300            Transform       -> setMatrix/getMatrix() etc methods removed,
1301                               Transform becoming the transform base class,
1302                               with MatrixTransform taking over all the original
1303                               functionality.
1304
1305
130619th July 2002 - OpenSceneGraph-0.9.0.tar.gz
1307
1308    >>> OpenSceneGraph goes beta - Multitexturing, Occlusion Culling, Particles and much more added!
1309
1310    This release marks the beginning of the beta phase of the OpenSceneGraph
1311    development, which means that all the major core features are now
1312    in the scene graph, and 1.0 is not far away.  Its performance, features
1313    and portability already compares very favorably to other scene graphs,
1314    both comerical and open source. 
1315
1316    Multi-texturing support added to osg::StateSet, osg::Geometry, osg::State
1317    and txp loader, so multi-texturing can now be done with very little coding
1318    from the user - all you need to do is specify the texture unit to use
1319    when setting texturing state and texture coordinates and the rest is
1320    handled automatically by the scene graph!
1321   
1322    The new osg::Geometry classes which supersedes the old Performer style
1323    osg::GeoSet, support multi-texturing, and uses sharable osg::Arrays which
1324    utilize std::vector<> for data storage and manipulation.
1325
1326    Shadow volume occlusion culling adding to the core OSG, developed as a
1327    collobaration between Mike Connell and Robert Osfield. Our implementation
1328    uses convex planer occluders, with support for holes to allow larger
1329    and more effective occluders to be used. The approach is software
1330    based so it 100% portable, and by culling during the cull traversal
1331    both CPU and GPU loads are significantly reduced, making it an extremely
1332    powerful feature for large scale urban and indoor visulisation.
1333
1334    osgParticle developed by Marco Jez adds support for a range of particle
1335    effects such smoke, fires, engine plumes, fountains, fire works, and
1336    is fully customizable to produce your own favorite effects. osgParticle
1337    is a NodeKit (see below) which can be directly linked to in your
1338    application to allow you to create particle effects by hand, or have
1339    the library dynamically loaded in when you load a database which contains
1340    particle effects.
1341   
1342    osgGA (Gui Abstraction) library written by Neil Salter adds classes for
1343    adapting different GUI toolkits to work with a standard set of manipulators for
1344    modifying the scene, such as camera and state manipulators.
1345   
1346    Support has been added to the plugin architecture to facilitate the
1347    development of NodeKits - add on libraries which can used directly
1348    in your code, or loaded indirectly when loading from file.  The
1349    later allows you to load a .osg file with text or particle effects
1350    in them,the plugin architecture automatically loads the required
1351    library which supports these features.
1352
1353    A range of new demos have been as code examples, and to demonstrate
1354    the range of features that OpenSceneGraph delivers:
1355
1356        osgoccluder  - demonstrates ocllusion culling, and has a mode
1357                       which allows the users to interactively create
1358                       their own convex planer occluders.
1359        osghud       - how to mix head up display with 3d views.
1360        osgparticle  - shows the new osgParticle node kit in action.               
1361        osgprerender - pre renders and scene then textures the result onto
1362                       an animated flag.
1363        osgcallback  - examples of the full range of callbacks that you
1364                       can use to add dynamic behaviors to your scene graph.
1365        osglight     - a simple example of how to set up spot and position
1366                       lights in the scene.
1367        osgclip      - illustrates how to add clip planes to you scene.
1368        osggeometry  - examples of the different ways to set up primitives
1369                       and vertex/color/normal and texture attributes in
1370                       the new osg::Geometry class.
1371        osgmultitexture - a simple example which adds a spherical reflection
1372                        map to a whole scene using the second texture unit
1373                        if one exists.
1374       
1375    osg::Drawable::PrimtiveFunctor has also been added to allow querrying
1376    of primitive data with Drawables subclasses without requiring knowledge
1377    of the types of Drawable subclasses that exists.  This decoupling makes
1378    it a very powerful and flexible utility.
1379
1380
138126th April 2002 - OpenSceneGraph-0.8.45.tar.gz
1382
1383    >>> Support added for Solaris, texture cube mapping & muliple projections.
1384   
1385    The OpenSceneGraph now has a new Makefile system which supports all Unix
1386    compilation including the new addition to the family - Solaris! 
1387
1388    OpenSceneGraph welcomes Solaris to the list of supported platforms.  This
1389    release puts all of the OpenSceneGraph functionality at the fingertips of
1390    Sun Microsystem's customers and developers.  Solaris users can now have
1391    the benefit of a high performance scene graph for visual simulation,
1392    virtual reality, scientific visualization, CAD, and architectural
1393    walk-throughs.  Many thanks to Sun for providing resources for the port.
1394   
1395    Additional html documentation has been added to the distribution to
1396    make it easier to get an understanding of scene graph technology and
1397    the project itself and how to make use of it. 
1398
1399    Support has also been added for OpenGL's texture cube mapping which
1400    is ideal for accurate environmental reflections and much more.
1401   
1402    The scene graph has been extended to allow multiple projection (via
1403    the new osg::Projection node) and viewports within one scene graphs,
1404    this makes it much easier to set up head up displays, and we have
1405    an example to demonstrate how easy it is - osghud.
1406   
1407    The osgUtil::CullVisitor and osgUtil::SceneView has been revamped
1408    removing the dependency on osg::Camera, which is now simply an
1409    option for SceneView rather than a requirement.  This allows users
1410    to set the camera entirely with the scene graph or create their own
1411    camera classes and use them with SceneView.  The existing osg::Camera
1412    has also been simplified as support for setting projection and
1413    modelview matrices have been moved out to the cull traversal.
1414   
1415    Several sets of node callbacks have been added, including a Cull
1416    NodeCallback on each Node, ComputeTransformCallback on Transform
1417    Nodes, EvaluateLODCallback on LOD nodes, ComputeBillboardCallback
1418    on Billboard nodes.  These make it my easier to customize the
1419    scene graphs behavior at runtime.
1420   
1421    osg::Image::readPixels() and support for writing .bmp files has been
1422    added which has made it easy to add screen capture the any OpenSceneGraph
1423    application.  This feature is demonstrated in the scene graph viewer
1424    which comes with the distribution - just press 'O' to output a screenshot.
1425   
1426    Finally, include/osg/MemoryManager has been added which overrides new
1427    and delete for debug builds. The override new and delete track allocations
1428    and deallocations, ensure they are matched, checked for memory under and
1429    overruns, and outputs a memleaks.log file on the results of executing
1430    your applications.  This help track down a number of memory leaks and
1431    unmatched new and deletes within the OpenSceneGraph and should make
1432    it easier to do with users applications as well.
1433   
1434    All in all, the OpenSceneGraph is now more portable, easier to
1435    customize, cleaner and more robust.  Beta release and 1.0 is now not
1436    far away!
1437   
1438
143924th February 2002 - osg-0.8.44.tar.gzosg-
1440
1441    >>> Support added for Mac OSX, Cygwin and MinGW, and new TerraPage loader.
1442   
1443    The major item for this release is the completion of the Mac OSX port,
1444    thanks to Phil Atkin and others for making this happen.
1445   
1446    Also added to support for Cygwin and MinGW builds which gives Windows
1447    users a free and robust alternative to the Visual C++, which we
1448    have Norman Vine to thank.
1449   
1450    Funtionality wise there has been a great deal of work behind the scenes
1451    putting in place a flexible and extensible framework for handling
1452    transform nodes, users can now extend the osg::Transform node through
1453    subclassing or via callbacks.  This work will underpin future work
1454    on moving camera setup into the scene graph, and environmental effects
1455    such as cloud layers, ground planes, stars and earth sky implementations
1456    which are planned for the next release.
1457   
1458    Callbacks and virtual methods have also been added to the osg::LOD &
1459    osg::Billboard to allow users to customize their behavior.  Draw
1460    callbacks have also been added to allow customization of osg::Drawables
1461    at runtime.
1462   
1463    The Open Flight .flt loader has undergone a number of improvements
1464    including support for instancing and billboards.
1465   
1466    New TerraPage (.txp) loader and OpenDX writer (.dx) plugins have been added.
1467   
1468    Support for the clone operation on osg::Object's has been expanded
1469    to allow cloneType() - a simple clone an blank object of the same type,
1470    and clone(CopyOp&) where CopyOp is a functor which allows users to
1471    specify the deep copy vs shallow copying of object data.
1472

14742nd January 2002 - osg-0.8.43.tar.gz
1475
1476    >>> Support for TrueType text, Stereo out of the box, and much more.
1477   
1478    Since the last release the OSG has moved to CVS based developments so
1479    many users will have seen gradual increments in functionality and changes
1480    to the API. Whereas a the leap from 0.8.42 to 0.8.43 is actually quite
1481    significant is likely to require code changes as several significant parts
1482    of the API have evolved to a more mature state.
1483   
1484    The most significant new functionality is the addition of the osgText
1485    library which provides support for true type font rendering, as textured,
1486    polygonal, pixmap, bitmap and 3D fonts.
1487   
1488    We now have new osg::Matrix implementation which cleans up its interface.
1489    Also all angular parameters are now based on radians rather than degrees
1490    as before (and as in Performer), this has been done to be more consistent
1491    with the basic trignometric functions and standard maths conventions.
1492   
1493    Scene graph optimization has been added which can boost performance
1494    on some database by as much as an order of magnititude, this is
1495    particularily noticable in .flt based databases.  Display list performance
1496    has also been boosted on NVidia based machines thanks to changing the
1497    compilation and execution of display list into two seperate operations.
1498   
1499    App callbacks are now supported on all Nodes, and there now a proper
1500    app traversal which can be used to animate the scene.
1501   
1502    Stereo support has been added into the osgUtil::SceneView which allows
1503    quad buffered/anaglyphic stereo to enabled easily for almost all OSG
1504    applications without code modifications - simple set environmental
1505    variable or pass in appropriate arguments and your app will render in
1506    stereo!
1507
1508    src/Demos/osgcluster has been added to demonstrate how easy it is
1509    to set up a graphics cluster across a standard networked PC's.
1510
1511    There have been many minor code changes to fix bugs and address
1512    performance bottlenecks or to improve extensibility was, representing
1513    a significant step towards API maturity and a beta release which is
1514    now not far away.

15179th August 2001 - osg-0.8.42.tar.gz
1518
1519    >>> New osgWX library for integration of OSG with wxWindows apps.
1520
1521    This release sees a relatively minor number of enhancements over
1522    0.8.41, the most significant being the new osgWX library and wxsgv
1523    demo written by Ben Discoe.
1524   
1525    Also from Brede Johansen in this release is the improvements in support for older
1526    .flt (Open Flight) files such versions 12 & 13.  Previously only version
1527    15.6 files had been tested and developed to.
1528   
1529    Last but by no means least, several bug fixes related to view frustum
1530    culling have been made.
1531
1532
153325th July 2001 - osg-0.8.41.tar.gz
1534
1535    >>> Support added for multi-pass and multi-stage rendering including Impostors.
1536
1537    The key feature developed is a highly flexible framework for multi-pass and
1538    multi-stage rendering techniques.  Unlike most scene graphs and games
1539    engines the OSG has as dynamic framework which automatically configures
1540    itself at runtime.
1541
1542    Building ontop of the new framework's multi-stage rendering capabilities,
1543    support for Impostors (hirachical image caching) has been integrated into
1544    the core scene graph  library making extremely easy to take advantage of
1545    this advanced rendering techinque - normally only seen in research papers.
1546    Check out osgimpostor demo to see how easy it is to add osg::Impostor
1547    nodes to your own models. Impostors are particularily effective are
1548    reducing scene complexity whilest minimizing the visual impact, making it
1549    ideal for scenes with large numbers of complex objects such as a city
1550    scene, or a dense forest.
1551   
1552    Taking advantage of the new framework's multi-pass rendering capabilities
1553    is osgreflect demo which illustrates how to achieve planar relfections
1554    using the stencil buffer and multi-pass rendering.
1555   
1556    The cool thing about both the osgreflect and osgimpostor demos is that
1557    there is no hardwiring to achieve the results, the scene graph stores
1558    all the information neccessary to specify the number and type of rendering
1559    passes, and the framework handles the rest behind the scenes.  This also
1560    makes it very easy to add these advanced rendering techinques to your
1561    own applications as everything is cleanly encapsulated with
1562    osgUtil::SceneView.
1563
1564    New loaders have been added to support .lwo (Light Wave), .obj
1565    (Alias Wavefront) and .dw (Design Workshop) 3D file formats making it
1566    even easier to compose your own worlds from models sourced from the
1567    web or your own.
1568   
1569    osg::Camera has been totally revamped and now supports asymetric
1570    and othographics projections in addition to the symetrical perspective
1571    projections.
1572
1573    And finally, support for texture subloading has been added to osg::Texture
1574    and osg::Image.  This allows textures to be updated dynamically, and
1575    has already been used for mpeg video playback!   
1576

157819th May 2001 - osg-0.8.40.tar.gz
1579
1580    >>> Project lead, Robert Osfield, makes full-time commitment to OSG.
1581
1582    This is the first full release since project lead, Robert Osfield, made
1583    a move to pursue the OSG's development full-time.  This commitment has
1584    been made to bring the API rapidly towards maturity, and to provide
1585    high quality support and consultancy services.  Please contact
1586    robert@openscenegraph.com if you have any queries.
1587
1588    This release marks a significant step forward in the maturity of the
1589    API, with several major changes to the library in the areas of state
1590    handling, database support, and portability.
1591
1592    To improve the extensibility of the OSG's handling of OpenGL state,
1593    new classes have been introduced to replace the previous hardwired
1594    state handling classes.  The new classes also allow improved state
1595    sorting and lazy state updating which boosts both cull traversal
1596    and particularly draw traversal performance.
1597
1598    To improve the modularity, interopability and conceptual clarity the
1599    support classes for database loading have been moved from the core
1600    osg library into their own osgDB library.  Support for the .osg
1601    ASCII native database format and the .rgb reader has moved into its own
1602    osgPlugins library to further the cleanliness of the core library.
1603
1604    Support has be added for multiple OpenGL context's and hence multi-pipe
1605    systems such as sgi's Onyx2, allowing each context to have its own
1606    display list and texture objects.
1607
1608    The culler and rendering support in osgUtil has also been improved, and
1609    significantly speeded up for complex models.
1610
1611    Also just in, thanks to Randall Hopper for adding support for FreeBSD :-)
1612

161423rd March 2001 - osg-0.8.39.tar.gz
1615
1616    >>> Port of OSG to MacOS underway
1617
1618    The first steps towards support of MacOS have been taken by Bryan Woods,
1619    adding Metrowerks project files and adding support for MacOS into the
1620    core scene graph.  Work still in progress so assistance welcome to
1621    complete the task.
1622
1623    Other major developments have been the addition of two new base classes
1624    osg::StateAttribute and osg::Drawable which are designed to allow greater
1625    extensibility of OpenGL state management and primitives.
1626
1627
162817th Feburary 2001 - osg-0.8.38.tar.gz
1629
1630    >>> New 3DS loader added
1631
1632    The OpenSceneGraph now supports the 3DS file format. This makes
1633    available a huge range of potential models. Check out
1634    http://www.3dcafe.com or http://www.3drocketfuel.com for some juice.
1635
163610th Feburary 2001 - osg_src-0.8-37.tar.gz
1637
1638    >>> Texture compression now supported
1639
1640    The OpenSceneGraph now provides support for ARB and S3TC texture
1641    compression. This allows more textures to be loaded onto graphics
1642    card memory, resulting in happier users and a better world in which
1643    to live.
1644
1645    This release also sees the addition of a simple hang gliding flight sim
1646    demo.
1647
164825th January 2001 - osg_src-0.8-35.tar.gz
1649
1650    >>> Anisotropic texturing now supported <i>and</i> loading of gzip compressed files
1651
1652    Anisotropic texturing provides for the next step in quality texturing
1653    filtering above tri-linear and is especially effective when viewing
1654    texture surfaces at shallow angles.
1655
1656    Also added in this release is on-the-fly support for loading gzipped
1657    (.osgtgz, .tgz) and zipped (.zip) database files.  This features allows
1658    users to store whole databases (models and textures) in a single
1659    tar ball and unpack them automatically on running the osg.  This
1660    is ideal for browsing the web.
1661
166222nd December 2000 - osg_src-0.8-33.tar.gz
1663
1664    >>> Support added for OpenGL vertex arrays, and several key image loaders.
1665   
1666    Support for OpenGL vertex arrays has been added to improve performance,
1667    particularly accelerating PC based graphics.
1668
1669    Also added is support gif, jpeg, pic, tga, tiff image formats via
1670    dynamic plugins.
1671
16728th Decemeber 2000 - osg_src-0.8-32.tar.gz
1673
1674    >>> New high resolution, low latency timer class - osg::Timer.
1675
1676    Real-time graphics relies upon accurate timers for updating physics
1677    simulations and managing constant framerates.  The OSG now provides
1678    osg::Timer which, when supported, takes advantage of hardware timers.
1679
1680
168118th November 2000 - osg_src-0.8-29.tar.gz
1682
1683    >>> Support for detail drawing with osg::PolygonOffset.
1684
1685    Rendering of polygons which overlay underlying geometry, such
1686    as white lines on a runway, can now be achieved utilizing the
1687    new osg::PolygonOffset which encapsulates glPolygonOffset to
1688    avoid z fighting which otherwise hampers such detailing.
1689
169010th November 2000 - osg_src-0.8-28.tar.gz
1691
1692    >>> New Open Flight .flt loader!
1693
1694    Thanks to Brede Johansen submission of .flt loader, the OSG can now
1695    read Open Flight .flt databases.
1696
16973rd November 2000 - osg_src-0.8-26.tar.gz
1698
1699    >>> Driving and Flight modes have been added to viewers.
1700
1701    osgUtil::DriveManipulator and osgUtil::FlightManipulator have been
1702    added to allow the scene graph viewer (sgv) and other viewers to
1703    support a drive and flying modes.  These modes can be accessed
1704    in sgv by pressing '2' and '3' respectively ('1' returns to
1705    trackball manipulator).  Left mouse button accelerates forward,
1706    middle stops motion and right deccelerates.
