370!!![=OpenSceneGraph=] 1.2 release introduces Windows 64bit and AIX support, COLLADA support, processor affinity and texture atlas builder.
371
372PERTHSHIRE, 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.
373
374The [=OpenSceneGraph=]-1.2 release introduces:
375
376* 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.
377* Support for IBM's AIX operating system, bringing the total number of supported operating systems to 8.
378* 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=].
379* 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.
380* 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.
381* 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.
382* A range of bug fixes and API refinements.
383
384The [=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.

496
49725th May 2005 - OpenSceneGraph-0.9.9
498
499>>> OpenGL Shading Language integrated into core, Introspection, movies, particle effects and much more... 
500
501Introduction to the OpenSceneGraph:
502
503The 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.
504   
505The OpenSceneGraph 0.9.9 release:
506   
507The 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.
508   
509The 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:
510       
511OpenGL Shader Language support:
512   
513OpenGL 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.
514       
515Introspection support:
516   
517The 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
518to 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.
519
520Better support for Apple native Windowing:
521
522Thanks 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.
523   
524Support for latest OpenGL extensions:
525   
526Support for the Non power of two texture feature of OpenGL 2.0 has been added
527to 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.
528   
529Terrain generation and rendering enhancements:
530   
531The 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.
532       
533Particle Effects:
534   
535To 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.
536   
537DXF and Movie plugins:
538   
539A 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.
540   
541Application and examples:
542   
543To 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.
544   
545There 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.
546   
547osgpbuffer also example now uses Producer's pbuffer support making it portable across platforms and much cleaner.
548   
549API refinements, bug fixes and performance improvements:
550   
551There 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.
552   
553We would like to thank the following engineers for their contributions in the 0.9.8 - 0.9.9.9 time frame (in alphabetic order):

647   
648
6499th August 2004 - OpenSceneGraph-0.9.7
650
651    >>> support for and generation of large scale geospatial databases,
652    >>> support for movies and examples of shadows and volume rendering.
653   
654    The 0.9.7 encompasses many improvements, bug fixes, new examples and
655    significant new functionality, the most notable of which is a new
656    osgTerrain library for generation of large scale geospatial databases.
657   
658    The new osgTerrain library and associated osgdem utility program
659    allows users to use moziacs of geospatial imagery and digital elevation
660    maps to generate a complete paged database which can be used with
661    standard OSG viewers, and users programs. By utilising GDAL to load the
662    imagery and DEM's a wide range of geospatial formats are supported.   
663     
664    The TerraPage plugin has also been rewritten ontop of the OSG's
665    osg::PagedLOD and osgDB::DatabasePager which provides support for the
666    tile fallback mechanism to ensure that no holes or cracks appear in the
667    databases being roamed, and to achieve constant frame rate via load
668    balancing mechanisms with osgDB::DatabasePager.
669   
670    The osgDB::DatabasePager has been further improved to provide more
671    configurable load balancing which allows application developers to achieve
672    constant frame rates when using paged databases.
673   
674    Double Vec & Matrix classes & CoordinateSystemNode/EllipsoidModel class
675    have been introduced to better support browsing of large scale databases,
676    and to provide a mechanism for tracking the local up orientation when
677    roaming whole earth databases.
678   
679    osgUtil has been enhanced with:
680     - an improved triangle tipper class (osgUtil::TriStipVisitor),
681     - a new simplifier (osgUtil::Simplifer) for reducing triangle density of
682       osg::Geometry leaves (utilised by osgTerrain to provide simplification
683       of terrain tiles),
684     - improved and more configurable optimizer (osgUtil::Optimizer),
685     - a new utility class for compiling and releasing OpenGL objects
686      (osgUtil::GLObjectVisitor) replaces the previous and more limited
687       DisplayListVisitor.
688   
689    All the osgGA::MatrxManipulator's (used for camera manipulator etc) have
690    been revamped with usage of doubles internally, and with tracking of the
691    current CoordinateSystem if one is active, to be better support whole
692    earth databases.  All the MatrixManipulators have been extend to allow
693    the setting of a user defined home position.  Two new manipulators have
694    been introduced osgGA::TerrainManipulator, for roaming whole earth/terrain
695    databases, and osgGA::TrackerManipulator which allows the camera to be
696    attached to a node in the scene graph.
697
698    Movie support under Linux and OSX via libMpeg3 and Quicktime respectively,
699    which extend the new osg::ImageStream base class which allows application
700    developers access to playing, pausing and rewinding movies.
701
702    The conversion utility osgconv has been extended to allow compression of
703    textures and mipmap generation during conversion when writing to the native
704    .ive binary format.  Texture compression and pre computer mipmaps enable
705    faster loading of databases and lower utilisation of memory resources.
706
707    Write support added to JPG plugin.
708   
709    Write + 3D texture support added to DDS plugin.
710   
711    Pseudo loaders .trans, .rot and .scale have been added.
712   
713    Updated LWO, AC3D, BMP, IVE and FLT loaders.
714   
715    osg::TexGenNode has been added to provide a mechanism for positioning
716    OpenGL's texture coordinate generation planes.
717
718    Fourteen new examples have been added:
719   
720        osgdem            a utility for creating large scale geospatial paged
721                          database
722

724                          geometry for paged in imagery
725
726        osgbluemarble     an example of how to build PagedLOD database for
727                          paging imagery

735                          shadow textures.
736
737        osgsimplifier     an example of how to use the new osgUtil::Simplifier.
738
739        osgspacewarp      an example of how to create a special effect that
740                          depends upon tracking the modelview matrix.
741
742        osgdistortion     an example of how to use prerendering of a texture to
743                          create a distortion effect.
744
745        osgsimple         a bare bones example of how to create a simple viewer
746                          using a Windowing toolkit, in this example using
747                          Producer, but is written so the example could easily
748                          be modified to work with other Windowing toolkit.
749
750        osgkeyboardmouse  adding to keyboard and mouse functionality on the
751                          osgsimple base.
752
753        osgsimplepager    adding database paging support to the osgsimple
754                          example.
755   
756        osgmovie          an example which creates a quad to render a loaded
757                          movie file with - requires the LibMpeg3 (Linux) or
758                          Quicktime (OSX) plugin to work.
759       
760        osgvolume         an example that reads a stack of 2d images to create
761                          a 3D texture, and creates a scene graph using
762                          standard OSG components (osg::ClipNode,
763                          osg::TexGenNode, osg::Billboard and
764                          osg::TexEnvCombine) to create a per per lit volume.
765
766   
767    Wrapping up the complete 0.9.7 release is a wide range of smaller features
768    enhancement and many bug fixes.
769
770
7712nd October 2003 - OpenSceneGraph-0.9.6-2
772
773    >>> osgFX Special Effects nodekit (for bumping mapping & cartoon effects etc), support for double Matrix traversals,
774    >>> improved build support, thread safety and robustness.
775   
776    The new osgFX nodekit, written by Marco Jez, adds a set of decorator
777    nodes that add can be conveniently added above subgraphs in your scene
778    to add special a range of special rendering effects.  Effects include
779    AnisotopicLight, BumpMapping, Scribe, Specular Highlights and Cartoon
780    rendering.
781   
782    Support for double Matrices has been added with the new Matrixd class,
783    and complimented by the a Matrixf class.  The original Matrix class is
784    now a typedef which can be set to either Matrixf or Matrixd (which is
785    now the default),  When the Matrix typedef is set to Matrixd and the OSG and
786    dependent apps are recompiled all internal operations such a cull traversals
787    will now be double with double matrices which much improved numerical
788    precision, making it ideal for datasets where a large values are contained
789    with transforms in the scene graph (such as with whole earth databases),
790    and when a transforms are nested which creates requires concatenation of
791    a number of matrices to get the final model view matrices. 
792   
793    The osgGA::MatrixManipulators (which are used to control the camera
794    position) and osgProducer/OpenProducer have been moved across to using
795    exclusively double Matrices.  This has been done to improve numerical
796    precision when computing camera positions, whilst having little impact
797    on performance since camera operations are only done a small number of
798    times per frame.
799   
800    osg::Quat now supports doubles by default, but also allows users to select
801    float version osg::Quat simply by changing the osg::Quat::value_type typedef.
802   
803    Work has been on OpenThreads and OpenProducer, in particular to improve
804    thread safety and robustness on the Win32 platform.  Reported crashes
805    on exit from osgProducer::Viewer based apps, and freezes during runtime
806    have been fixed.
807   
808    Threading problems which caused crashes in recent updates of the Terrapage
809    loader have also been fixed, and additional internal changes have been made
810    to improve the Terrapage loader's ability to hit constant frame rates.   
811    Support has also been added for loading light points directly from the
812    Terrapage database.
813
814    A new .iv/.wrl loader plugin, written by Vivek Rajan, at Magic Earth,
815    has been added to the distribution which uses with OpenInventor or Coin
816    to load model, converting them into OSG equivalents.  Coin has support
817    for VRML97 models, so can be used to import such models into the OSG. 
818    Since the new plugin is dependent on OpenInventor or Coin the compilation
819    is optional, but off by default. To compile this plugin under Unix, set
820    the environmental variable USE_INVENTOR or USE_COIN and recompile. 
821    Windows .dsp project file does to current exist, but should be
822    possible to add this.
823   
824    The .ive plugin has been improved with the addition of support for
825    osgSim light points, and various internal refinements to make it function
826    better on the various platforms supported by the OSG.  Note, these changes
827    mean that the .ive format has has changed and is no longer compatible
828    with previous version of .ive. It is recommend that one recreates .ive
829    for the original source via osgconv or similar to ensure consistency.
830
831    A JPEG2000 image plugin has added, written by Michael Gronager.  The new jp2
832    plugin uses the japser open source project to read and write JPEG2000 files.
833   
834    A scalar bar, and sphere segment helper classes have been added to osgSim,
835    the new osgscalarbar and osgspheresegment examples demonstrate how to use
836    these new features.
837   
838    To help handle running applications of graphics cards/drivers that exhibit
839    bugs with certain OpenGL extensions, support has been added to the GLextensions
840    code to allow extensions to be disabled via the new
841    osg::setGLExtensionDisableString(std::string) function or by setting an
842    OSG_GL_EXTENSION_DISABLE environmental variables.  Follows is an example of
843    the disable string:
844   
845        set OSG_GL_EXTENSION_DISABLE =
846             "ATI:GL_SGIS_generate_mipmap;Sun:GL_EXT_texture_filter_anisotropic:"
847
848    New examples include:
849   
850        osgforest - an example which demonstrates simple techniques for creating forests   
851        osgfxbrowser - an example which demonstrates the various osgFX Effects available   
852        osgscalabar - an example of how to set up the osgSim::ScalarBar.
853        osgspheresegment - an example of how to set up the osgSim::SphereSegement
854        osgpagelod - a very simply test program for setting up osg::PagedLOD/osgDB::DatabasePager
855   
85623rd July 2003 - OpenSceneGraph-0.9.5
857
858    >>> Support added for OpenGL2.0 shaders, native multi-threaded Database paging,
859    >>> high peformance binary format reading and writing,  .dds compressed image
860    >>> loader and ARB_fragment_program and ARB_vertex_buffer_object extensions,
861    >>> improvements to the Terrex .txp and OpenFlight .flt loaders.
862
863    The key new features of the 0.9.5 release are the new OpenGL2.0 nodekit, constant frame rate
864    database paging support,  classes,  and the new native .ive binary plugin which supports
865    both reading and writing of all core osg nodes, including inlining of compressed
866    and non-compressed imagery.
867   
868    The native database paging support, provided by the new osg::PageLOD and osgDB::DatabasePager,
869    achieves constant frame rate through threading of the database reading, and time based
870    incremental compile and delete of display lists, vertex_buffer_objects and texture objects.
871    A new TextureObjectManager class also caches a list of expired texture objects for reuse,
872    and allows new newly loading imagery to reuse expired texture objects, with the imagery
873    automatically subloaded to the reused texture objects.  This reuse happens transparently
874    and benefits other OSG usages such as the OSG's Terrapage loader.
875   
876    To provide support multi-thread operation of the OSG, such as multi-thread database paging
877    and multi-threaded, multi-window graphics enabled by OpenProducer, the OpenSceneGraph and
878    OpenProducer have now adopted the OpenThreads threading library, osgDB and osgProducer now
879    depend upon it.  OpenThreads is open source, light weight, cross platform C++ threading
880    which encapsulates the low level, platform specific threading API calls.  Currently pthreads
881    under Unix and Win32 threads under Windows are supported, with Sgi sproc threads to be
882    released very soon.  The OpenThreads project website can be found at http://openthreads.sf.net.   
883
884    The new .ive binary plugin was developed by Uni-C's VR-Center, and kindly submitted as
885    open source, adds support for binary reading and writing OSG nodes drawable and state
886    (including compressed/mipmapped) textures.  The .ive format produces a much faster
887    load times and smaller file size then native ASCII .osg format. Load times for .ive
888    files are also 10-20x faster then equivalent OpenFlight .flt and load in an already
889    optimized scene graph form making it much more suitable for paging.  Files can be
890    converted easily using the osgconv utility : osgconv myfile.flt myfile.ive
891   
892    The new osgGL2 nodekit library adds support for the OpenGL2.0 vertex ProgramObect and fragment
893    ShaderObject's recently ratified by the OpenGL ARB, . The osgGL2 uses the extension have local
894    prototypes which allow them to be compiled even in the absence of OpenGL headers that don't
895    support the GL2 extension, allowing to port to all platform, and at runtime the extensions are
896    queried for and used if available.  At time of release only 3DLabs WildcatVP series supported
897    this extension at runtime, but other graphics cards and manufactures will be releasing GL2
898    extension very soon and will be automatically supported by osgGL2. The osgGL2 was developed
899    by Mike Weiblen at 3DLabs whom have kindly submitted osgGL2 as open source and for inclusion
900    with the OSG distribution. 
901
902    The ARB_fragment_program, ARB_vertex_buffer_object and ARB_vertex_program attributes are
903    also now supported in core osg library.  The new osg::FragmentProgram state attribute
904    encapsulates the ARB_fragment_program which is supported by the recent graphics cards
905    from NVidia, ATI and 3DLabs.  Support for ARB_vertex_buffer_object and ARB_vertex_program
906    attributes have been added to the osg::Geometry class.  The ARB_vertex_buffer_object extension
907    can boost performance by as much as 50% when working on geometry bound data sets.
908
909    Two new image loaders, dds and pnm, and a 3dc point cloud have been added. The .dds plugin
910    adds support for compressed & mipped mapped imagery, making it ideal for applications where
911    large texture sizes or database paging is required. The pnm image loader reads the
912    pnm, pgm and pbm image formats. See http://netghost.narod.ru/gff/vendspec/pbm/ for details.
913
914    The Terrapage .txp plugin  been updated to include support for multi-texturing, layers and billboards
915    and includes improvements to multi-threaded pager, which has also been ported over to use OpenThreads.
916    The OpenFlight .flt plugin has also been improved and now support detail textures via multi-texturing.
917
918    TessellationHints now supported by ShapeDrawable which allow the shape primitives to be rendered
919    are vary levels of detail.
920
921    Supported has been added for auto scaling and rotating text into osgText.
922
923    Five new examples have been included in the distribution:
924   
925        osgtexturerectangle illustrates how to use the osg::TextureRectangle which encapsulates
926        the NV_texture_rectangle extension.
927       
928        osgprerendercubemap illustrates how to use pre rendering imagery to osg::TextureCubeMap
929        for tasks such as building a environmental texture maps.
930       
931        slideshow3D is a presentation tool which use a scene graph to store a render set of slides, each
932        slide containing layers which can contain bullet points, paragraph, imagery and 3d animated
933        models - and is effectively a 3D power point. The presentations can be built separately and stored in a .osg file or created by
934        slideshow3D via an xml file, two examples - introduction.xml and models.xml, which are included
935        in the OpenSceneGraph-Data-0.9.5 data distribution.  slideshow3D depends upon libxml2 for parsing
936        the xml files.
937       
938        osgpoints uses the osg::Point state attribute to attenuate and control point size and any points
939        loaded by the application.  This is a useful way of visualizing point data clouds.
940       
941        osgdemeter is example of how to integrate the Demeter, OSG using osgProducer::Viewer as a viewer
942        class.  This example depends upon the demeter terrain engine, which can be download from
943        http://www.terrainengine.com.
944
945    Camera style convenience set and get methods to osgUtil::SceneView, consolidating
946    previous functionality that was provided by both osg::SceneView and osg::Camara into one place.
947    This move has made osg::Camera redundant so has it been removed to avoid confusion,
948    usage inconsistencies and bloat of core libraries.
949   
950    The long time deprecated osg::GeoSet has been removed, to aid migration of old .osg datasets
951    osgconv has a copy of GeoSet and the .osg support for it so is able to convert any remaining
952    .osg database which contained GeoSet's.
953
954   
955
95628th April 2003  - OpenSceneGraph-0.9.4-2
957
958    >>> Multi-threaded, multi-pipe support via integration with OpenProducer,
959    >>> 64bit Linux support for Intel Intanium and AMD Opteron,
960    >>> new osgText library with greater performance, and thread safety,
961    >>> new DDS plug-in for compressed and non-compressed images,
962    >>> new MD2 plug-in adds support for animate Quake character and
963    >>> support added for NV_texture_rectangle.
964
965    The most significant new feature is the osgProducer library that adds
966    tight integration with OpenProducer, providing the OpenSceneGraph with a
967    scalable, configurable and portable framework for developing real-time
968    and interactive graphics applications.  The scalability afforded by
969    OpenProducer allows applications to be developed which run seamlessly
970    on single pipe machines up to multi-pipe machines such as Sgi Onyx
971    IR system, and Sun Zulu systems.
972    The osgProducer/OpenProducer framework automatically handles the
973    multi-threading of cull-draw pairs and GUI events.
974
975    All the example programs have been ported over from being based on
976    GLUT to using osgProducer (osgGLUT can now be found in the bazaar
977    section on the website). The move to osgProducer allows all the examples
978    to scale from running on laptops up to multiple CPU and graphics pipe systems.
979    The configuration of threading and multiple camera views can all be done
980    via ASCII configuration files, no need to recompile.  A number of
981    new examples have also been added or revamped, bringing the total to 42.
982
983    Also in the theme of increasing scalability there is support for 64bit Linux for both
984    IA64 (Intel Itanium) and x86-64 (AMD Opteron) which compliments the existing
985    support for Solaris and IRIX 64 bit compilation.  64 bit supports allows
986    the use of very large data sets, and potential performance improvements.
987
988    To help support development teams working with multiple build configuration,
989    the makefile system has been extended to allow multiple build targets to be
990    built from one source code base.  All makefiles are also now named GNUmakefile
991    which ensures that they are only run by gmake to avoid an confusion on system
992    where gmake isn't the default make tool.
993
994    A completely new osgText implemention has been developed which is simpler
995    to use, faster, and thread safe.  Support for high quality true type fonts
996    has now been moved to a freetype plug-in which is dynamically loaded on demand,
997    with the core osgText library providing a default font when the plug-in is
998    unavailable.  Moving the freetype dependency out of the osgText library makes
999    it just dependant on OpenGL and Standard C++ like the rest of the core libraries,
1000    allowing osgText to compile by default on all platforms.
1001
1002    Improved thread safety has also been achieved in the core osg and osgUtil libraries
1003    making work on multiple CPU/multi-pipe systems robust and with improved performance.
1004
1005    Two new plug-ins have been added, for loading DDS and MD2 data formats. The DDS plug-in
1006    is for loading compressed and non-compressed images.  The MD2 plug-in loads Quake
1007    animated characters.
1008   
1009    osg::TextureRectangle class has been added, which encapsulates the
1010    NV_texture_rectangle and EXT_texture_rectangle extensions.  This is particularly
1011    useful for render to texture algorithms, and dynamic paging of images such as for
1012    rendering video streams.
1013
1014    Support for automatic subloading of osg::Texture2D textures has been added
1015    so that when image data is updated the corresponding OpenGL texture is
1016    automatically updated - no need for callbacks.  Also added to the osg::Texture
1017    classes is the option of automatic unref'ing of texture image data once the data has
1018    been download to all active OpenGL graphics contexts.
1019   
1020    A new osgUtil::DelaunayTriangulator utility class has been added.  This is ideal for
1021    creating optimal triangular meshes from unconnected data points.
1022
1023    Two new classes, osg::ArgumentParser and osg::ApplicationUsage, have been introduced
1024    to convineiently and robustly parse command line arguments and
1025    report command line usage, environmental variables and keyboard and mouse bindings
1026    used by applications.  Running any of the examples with -h or --help will report
1027    full details example usage.  Keyboard and Mouse bindings usage is now also available as
1028    a HUD on all examples, simply press 'h' while the app is running to
1029    bring up help.
1030
1031    A database cache in the osgDB library has been added, along with a clean up
1032    of memory management in the OpenFlight loader, make development of
1033    dynamic paging of databases easier and more robust.
1034   
1035    Support for early abort of rendering has been added, which is useful for
1036    interactive applications which occasionally have rendering that takes that long
1037    enough (i.e.several seconds) that end users may wish to abort during the drawing.
1038
1039    There have also been many general API improvements and bug fixes, too many to enumerate,
1040    but all go to solidify the quality of the scene graph and its accompanying libraries. 
1041   
1042    The combination of new features, robustness and scalability mark this release as a
1043    significant step towards 1.0.

1049    >>> adds support navigational light points, multi-threaded dynamic
1050    >>> paging of Terrapage databases, ARB_vertex_program extension,
1051    >>> DirectD .x model loader, and integration with OpenProducer for
1052    >>> multi-threaded, multi-window/pipe rendering.
1053
1054    Added osgProducer library which integrates the OpenSceneGraph seemlessly
1055    with OpenProducer to provide runtime configurable management of windows
1056    and multipipe graphic systems.  The osgproducer demo illustrate how
1057    developers can write applications very simply that harness the power
1058    of the OpenProducer and OpenSceneGraph in an extremely flexible way.
1059    OpenProducer can be downloaded from:
1060    http://www.andesengineering.com/BlueMarbleViewer/producer_install.html
1061
1062    Support added for dynamic paging of Terrage databases, the required
1063    multi-threading is set up by defult.  All the end user application need
1064    to do is load the database and the paging then happens automatically -
1065    without any need for intervention by the users application.
1066
1067    Addition of osgSim which is NodeKit designed for visual simulation
1068    market, currently features high fidelity light points support.  Light
1069    point sectors, blink sequences and groups, and light point fading are
1070    all supported.
1071
1072    From Brede Johansen, support added for the ARB VertexProgram extension
1073    with osgvertexprogram demo showing reflection and refraction in action, and
1074    osgpbuffer demo for Win32.

1081    dynamic shadow textures in your scene.
1082
1083    New osglogo demo - features anti-aliased TrueType text and animation.
1084   
1085    The app phase of operations on the scene graph has been renamed
1086    the update phase to make its function clearer. The main phases are now
1087    named now does update, cull, draw.  The AppVisitor, set/getAppCallback etc
1088    have be renamed UpdateVisitor, set/getUpdateCallback etc.
1089
1090    Removed the osg/ManagerManger and associated #define osgNew's, this has
1091    been done to simplify users code and to solve the lack of thread safety
1092    that was causing problems with the MemoryManager.
1093   
1094    Support added for reading and writing of callbacks in the .osg format.
1095   
1096    Support added for reading and writing of osg::Shapes in the .osg format.
1097
1098    Support added for reading OpenFlight comment records into osg::Node description
1099    fields.

1107
1108    >>> New AC3D and GEO loaders, new Shape primitives, improved OpenFlight support.
1109
1110    From Geoff Michel, AC3D .wc and Carbon Graphics GEO .geo loaders.
1111
1112    Support for multi-texturing added to OpenFlight loader.
1113   
1114    LOD has been revamped to allow independent min and max ranges for
1115    each LOD child, bringing it inline with the OpenFlight style LOD
1116    representation.
1117
1118    Switch has been revamped to allow independent switching on or off of
1119    each Switch child, bringing it inline with the OpenFlight style Switch
1120    representation.
1121
1122    New osg::Shape geometry primitives added which allow the specification
1123    of geometry in a form that can accelerate collision detection, and as
1124    a way of specifying the geometry to tessellate.  Shapes include
1125    Sphere, Oriented Box, Cone, Cylinder, Grid, TriangleMesh, ConvexHull
1126    and CompositeShape which allows the storage of a hierarchy of shapes.
1127   
1128    Geometry has been extended to all per primitive bindings and
1129    per primitive set bindings of attributes, and indexing of attributes
1130    with the same or different index lists for each attribute list.
1131
1132    From Macro Jez, new cubemap helper classes.
1133
1134    Support added for handling different extensions on different graphics
1135    contexts.

1142    Renamed classes :
1143   
1144        Primitive    -> PrimitiveSet
1145       
1146    Renamed methods :
1147   
1148        Geometry::addPrimitive(..) -> addPrimitiveSet(..)
1149        Drawable::drawImmediateMode(..) -> drawImplementation(..) const
1150        Drawable::DrawCallback::drawImmediateMode(..) -> drawImplementation(..) const

1154
1155    >>> 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!
1156
1157    Despite only 6 weeks passing between 0.9.0 and this latest 0.9.1 release
1158    there has been a number of significant new features, API clean ups and
1159    bug fixes.  Follows is a quick run through the key improvements.
1160
1161    Addition of osg::Texture1D, Texture2D & Texture3D classes, Texture2D replaces
1162    the original osg::Texture, which has now become a pure virtual base class. All
1163    Texture classes, including TextureCubeMap are derived from this base class..
1164   
1165    New osgtexture1D and osgtexture3D demos demonstrate the new texture classes in
1166    action.
1167   
1168    The build system has been updated to support HP-UX.  This adds one of the last
1169    remaining mainstream platforms supported.
1170
1171    A new Inventor/VRML1.0 loader was added.  The inventor format has been requested
1172    on numerous occasions, so this is a welcome addition.
1173   
1174    Support added to lwo plugin for loading the new lwo2 format.
1175
1176    osg::TexEnvCombine implemented texture_env_combine and texture_env_crossbar
1177    and texture_env_dot3 extensions.
1178
1179    osg::TexEnv texture_env_add added.
1180
1181    A osg::Sequence node has finally been implemented.  It is accompanied by a
1182    demo, osgsequence.
1183
1184    osg::DOFTransformNode implemented.
1185
1186    Support for OpenFlight15.7 added, DOFTransforms and general enhancements and
1187    bug fixes.
1188
1189    New PROTECTED mode for protecting local state mode and attributes from be
1190    overridden from state above it in the scene graph.
1191   
1192    Support for fog coord and secondary colors extensions added to osg::Geometry.
1193
1194    osg::Billboard has been improved to allow rotations around all axes, as well
1195    as point rotations.  Check osgbillboard for a new improved demo.
1196
1197    The osglight example has been improved by utilizing AnimationPath and
1198    PositionAttitudeTransform to keep light sources in motion.
1199
1200    osg::AnimationPath improved, now allowing swing and looping behavior and
1201    with two new app callbacks which can update PositionAttitudeTransform
1202    and MatrixTransform respectively.
1203   
1204    Support for writing osg::Image's to .rgb format added.
1205
1206    To keep the overall API clean, and the following items have been
1207    renamed and deprecated parts of the API have been removed:
1208
1209    Renamed classes:
1210
1211            EarthSky        -> ClearNode
1212            Transparency    -> BlendFunc
1213            Texture         -> Texture2D  (old style subload parameters removed)
1214
1215    Method's changed
1216
1217            Matrix          -> makeRotate(..) euler angles parameters generalized.
1218            Quat            -> makeRotate(..) euler angles parameters generalized.
1219
1220            BoundingBox     -> isValid() renamed valid()
1221            BoundingSphere  -> isValid() renamed valid()
1222
1223            StateAttribute  -> OVERRIDE_OFF & OVERRIDE_ON which were short hand
1224                               versions of OVERRIDE | OFF and OVERRIDE | ON
1225                               removed, as the meaning of the bitmask was
1226                               often confused by the short hand notation.
1227
1228
1229            Transform       -> setMatrix/getMatrix() etc methods removed,
1230                               Transform becoming the transform base class,
1231                               with MatrixTransform taking over all the original
1232                               functionality.
1233

123519th July 2002 - OpenSceneGraph-0.9.0.tar.gz
1236
1237    >>> OpenSceneGraph goes beta - Multitexturing, Occlusion Culling, Particles and much more added!
1238
1239    This release marks the beginning of the beta phase of the OpenSceneGraph
1240    development, which means that all the major core features are now
1241    in the scene graph, and 1.0 is not far away.  Its performance, features
1242    and portability already compares very favorably to other scene graphs,
1243    both comerical and open source. 
1244
1245    Multi-texturing support added to osg::StateSet, osg::Geometry, osg::State
1246    and txp loader, so multi-texturing can now be done with very little coding
1247    from the user - all you need to do is specify the texture unit to use
1248    when setting texturing state and texture coordinates and the rest is
1249    handled automatically by the scene graph!
1250   
1251    The new osg::Geometry classes which supersedes the old Performer style
1252    osg::GeoSet, support multi-texturing, and uses sharable osg::Arrays which
1253    utilize std::vector<> for data storage and manipulation.
1254
1255    Shadow volume occlusion culling adding to the core OSG, developed as a
1256    collobaration between Mike Connell and Robert Osfield. Our implementation
1257    uses convex planer occluders, with support for holes to allow larger
1258    and more effective occluders to be used. The approach is software
1259    based so it 100% portable, and by culling during the cull traversal
1260    both CPU and GPU loads are significantly reduced, making it an extremely
1261    powerful feature for large scale urban and indoor visulisation.
1262
1263    osgParticle developed by Marco Jez adds support for a range of particle
1264    effects such smoke, fires, engine plumes, fountains, fire works, and
1265    is fully customizable to produce your own favorite effects. osgParticle
1266    is a NodeKit (see below) which can be directly linked to in your
1267    application to allow you to create particle effects by hand, or have
1268    the library dynamically loaded in when you load a database which contains
1269    particle effects.
1270   
1271    osgGA (Gui Abstraction) library written by Neil Salter adds classes for
1272    adapting different GUI toolkits to work with a standard set of manipulators for
1273    modifying the scene, such as camera and state manipulators.
1274   
1275    Support has been added to the plugin architecture to facilitate the
1276    development of NodeKits - add on libraries which can used directly
1277    in your code, or loaded indirectly when loading from file.  The
1278    later allows you to load a .osg file with text or particle effects
1279    in them,the plugin architecture automatically loads the required
1280    library which supports these features.
1281
1282    A range of new demos have been as code examples, and to demonstrate
1283    the range of features that OpenSceneGraph delivers:
1284
1285        osgoccluder  - demonstrates ocllusion culling, and has a mode
1286                       which allows the users to interactively create
1287                       their own convex planer occluders.
1288        osghud       - how to mix head up display with 3d views.
1289        osgparticle  - shows the new osgParticle node kit in action.               
1290        osgprerender - pre renders and scene then textures the result onto
1291                       an animated flag.
1292        osgcallback  - examples of the full range of callbacks that you
1293                       can use to add dynamic behaviors to your scene graph.
1294        osglight     - a simple example of how to set up spot and position
1295                       lights in the scene.
1296        osgclip      - illustrates how to add clip planes to you scene.
1297        osggeometry  - examples of the different ways to set up primitives
1298                       and vertex/color/normal and texture attributes in
1299                       the new osg::Geometry class.
1300        osgmultitexture - a simple example which adds a spherical reflection
1301                        map to a whole scene using the second texture unit
1302                        if one exists.
1303       
1304    osg::Drawable::PrimtiveFunctor has also been added to allow querrying
1305    of primitive data with Drawables subclasses without requiring knowledge
1306    of the types of Drawable subclasses that exists.  This decoupling makes
1307    it a very powerful and flexible utility.
1308

131026th April 2002 - OpenSceneGraph-0.8.45.tar.gz
1311
1312    >>> Support added for Solaris, texture cube mapping & muliple projections.
1313   
1314    The OpenSceneGraph now has a new Makefile system which supports all Unix
1315    compilation including the new addition to the family - Solaris! 
1316
1317    OpenSceneGraph welcomes Solaris to the list of supported platforms.  This
1318    release puts all of the OpenSceneGraph functionality at the fingertips of
1319    Sun Microsystem's customers and developers.  Solaris users can now have
1320    the benefit of a high performance scene graph for visual simulation,
1321    virtual reality, scientific visualization, CAD, and architectural
1322    walk-throughs.  Many thanks to Sun for providing resources for the port.
1323   
1324    Additional html documentation has been added to the distribution to
1325    make it easier to get an understanding of scene graph technology and
1326    the project itself and how to make use of it. 
1327
1328    Support has also been added for OpenGL's texture cube mapping which
1329    is ideal for accurate environmental reflections and much more.
1330   
1331    The scene graph has been extended to allow multiple projection (via
1332    the new osg::Projection node) and viewports within one scene graphs,
1333    this makes it much easier to set up head up displays, and we have
1334    an example to demonstrate how easy it is - osghud.
1335   
1336    The osgUtil::CullVisitor and osgUtil::SceneView has been revamped
1337    removing the dependency on osg::Camera, which is now simply an
1338    option for SceneView rather than a requirement.  This allows users
1339    to set the camera entirely with the scene graph or create their own
1340    camera classes and use them with SceneView.  The existing osg::Camera
1341    has also been simplified as support for setting projection and
1342    modelview matrices have been moved out to the cull traversal.
1343   
1344    Several sets of node callbacks have been added, including a Cull
1345    NodeCallback on each Node, ComputeTransformCallback on Transform
1346    Nodes, EvaluateLODCallback on LOD nodes, ComputeBillboardCallback
1347    on Billboard nodes.  These make it my easier to customize the
1348    scene graphs behavior at runtime.
1349   
1350    osg::Image::readPixels() and support for writing .bmp files has been
1351    added which has made it easy to add screen capture the any OpenSceneGraph
1352    application.  This feature is demonstrated in the scene graph viewer
1353    which comes with the distribution - just press 'O' to output a screenshot.
1354   
1355    Finally, include/osg/MemoryManager has been added which overrides new
1356    and delete for debug builds. The override new and delete track allocations
1357    and deallocations, ensure they are matched, checked for memory under and
1358    overruns, and outputs a memleaks.log file on the results of executing
1359    your applications.  This help track down a number of memory leaks and
1360    unmatched new and deletes within the OpenSceneGraph and should make
1361    it easier to do with users applications as well.
1362   
1363    All in all, the OpenSceneGraph is now more portable, easier to
1364    customize, cleaner and more robust.  Beta release and 1.0 is now not
1365    far away!
1366   
1367
136824th February 2002 - osg-0.8.44.tar.gzosg-
1369
1370    >>> Support added for Mac OSX, Cygwin and MinGW, and new TerraPage loader.
1371   
1372    The major item for this release is the completion of the Mac OSX port,
1373    thanks to Phil Atkin and others for making this happen.
1374   
1375    Also added to support for Cygwin and MinGW builds which gives Windows
1376    users a free and robust alternative to the Visual C++, which we
1377    have Norman Vine to thank.
1378   
1379    Funtionality wise there has been a great deal of work behind the scenes
1380    putting in place a flexible and extensible framework for handling
1381    transform nodes, users can now extend the osg::Transform node through
1382    subclassing or via callbacks.  This work will underpin future work
1383    on moving camera setup into the scene graph, and environmental effects
1384    such as cloud layers, ground planes, stars and earth sky implementations
1385    which are planned for the next release.
1386   
1387    Callbacks and virtual methods have also been added to the osg::LOD &
1388    osg::Billboard to allow users to customize their behavior.  Draw
1389    callbacks have also been added to allow customization of osg::Drawables
1390    at runtime.
1391   
1392    The Open Flight .flt loader has undergone a number of improvements
1393    including support for instancing and billboards.
1394   
1395    New TerraPage (.txp) loader and OpenDX writer (.dx) plugins have been added.
1396   
1397    Support for the clone operation on osg::Object's has been expanded
1398    to allow cloneType() - a simple clone an blank object of the same type,
1399    and clone(CopyOp&) where CopyOp is a functor which allows users to
1400    specify the deep copy vs shallow copying of object data.
1401   
1402
14032nd January 2002 - osg-0.8.43.tar.gz
1404
1405    >>> Support for TrueType text, Stereo out of the box, and much more.
1406   
1407    Since the last release the OSG has moved to CVS based developments so
1408    many users will have seen gradual increments in functionality and changes
1409    to the API. Whereas a the leap from 0.8.42 to 0.8.43 is actually quite
1410    significant is likely to require code changes as several significant parts
1411    of the API have evolved to a more mature state.
1412   
1413    The most significant new functionality is the addition of the osgText
1414    library which provides support for true type font rendering, as textured,
1415    polygonal, pixmap, bitmap and 3D fonts.
1416   
1417    We now have new osg::Matrix implementation which cleans up its interface.
1418    Also all angular parameters are now based on radians rather than degrees
1419    as before (and as in Performer), this has been done to be more consistent
1420    with the basic trignometric functions and standard maths conventions.
1421   
1422    Scene graph optimization has been added which can boost performance
1423    on some database by as much as an order of magnititude, this is
1424    particularily noticable in .flt based databases.  Display list performance
1425    has also been boosted on NVidia based machines thanks to changing the
1426    compilation and execution of display list into two seperate operations.
1427   
1428    App callbacks are now supported on all Nodes, and there now a proper
1429    app traversal which can be used to animate the scene.
1430   
1431    Stereo support has been added into the osgUtil::SceneView which allows
1432    quad buffered/anaglyphic stereo to enabled easily for almost all OSG
1433    applications without code modifications - simple set environmental
1434    variable or pass in appropriate arguments and your app will render in
1435    stereo!
1436
1437    src/Demos/osgcluster has been added to demonstrate how easy it is
1438    to set up a graphics cluster across a standard networked PC's.
1439
1440    There have been many minor code changes to fix bugs and address
1441    performance bottlenecks or to improve extensibility was, representing
1442    a significant step towards API maturity and a beta release which is
1443    now not far away.
1444

1448    >>> New osgWX library for integration of OSG with wxWindows apps.
1449
1450    This release sees a relatively minor number of enhancements over
1451    0.8.41, the most significant being the new osgWX library and wxsgv
1452    demo written by Ben Discoe.
1453   
1454    Also from Brede Johansen in this release is the improvements in support for older
1455    .flt (Open Flight) files such versions 12 & 13.  Previously only version
1456    15.6 files had been tested and developed to.
1457   
1458    Last but by no means least, several bug fixes related to view frustum
1459    culling have been made.

1463
1464    >>> Support added for multi-pass and multi-stage rendering including Impostors.
1465
1466    The key feature developed is a highly flexible framework for multi-pass and
1467    multi-stage rendering techniques.  Unlike most scene graphs and games
1468    engines the OSG has as dynamic framework which automatically configures
1469    itself at runtime.
1470
1471    Building ontop of the new framework's multi-stage rendering capabilities,
1472    support for Impostors (hirachical image caching) has been integrated into
1473    the core scene graph  library making extremely easy to take advantage of
1474    this advanced rendering techinque - normally only seen in research papers.
1475    Check out osgimpostor demo to see how easy it is to add osg::Impostor
1476    nodes to your own models. Impostors are particularily effective are
1477    reducing scene complexity whilest minimizing the visual impact, making it
1478    ideal for scenes with large numbers of complex objects such as a city
1479    scene, or a dense forest.
1480   
1481    Taking advantage of the new framework's multi-pass rendering capabilities
1482    is osgreflect demo which illustrates how to achieve planar relfections
1483    using the stencil buffer and multi-pass rendering.
1484   
1485    The cool thing about both the osgreflect and osgimpostor demos is that
1486    there is no hardwiring to achieve the results, the scene graph stores
1487    all the information neccessary to specify the number and type of rendering
1488    passes, and the framework handles the rest behind the scenes.  This also
1489    makes it very easy to add these advanced rendering techinques to your
1490    own applications as everything is cleanly encapsulated with
1491    osgUtil::SceneView.
1492
1493    New loaders have been added to support .lwo (Light Wave), .obj
1494    (Alias Wavefront) and .dw (Design Workshop) 3D file formats making it
1495    even easier to compose your own worlds from models sourced from the
1496    web or your own.
1497   
1498    osg::Camera has been totally revamped and now supports asymetric
1499    and othographics projections in addition to the symetrical perspective
1500    projections.
1501
1502    And finally, support for texture subloading has been added to osg::Texture
1503    and osg::Image.  This allows textures to be updated dynamically, and
1504    has already been used for mpeg video playback!

1509    >>> Project lead, Robert Osfield, makes full-time commitment to OSG.
1510
1511    This is the first full release since project lead, Robert Osfield, made
1512    a move to pursue the OSG's development full-time.  This commitment has
1513    been made to bring the API rapidly towards maturity, and to provide
1514    high quality support and consultancy services.  Please contact
1515    robert@openscenegraph.com if you have any queries.
1516
1517    This release marks a significant step forward in the maturity of the
1518    API, with several major changes to the library in the areas of state
1519    handling, database support, and portability.
1520
1521    To improve the extensibility of the OSG's handling of OpenGL state,
1522    new classes have been introduced to replace the previous hardwired
1523    state handling classes.  The new classes also allow improved state
1524    sorting and lazy state updating which boosts both cull traversal
1525    and particularly draw traversal performance.
1526
1527    To improve the modularity, interopability and conceptual clarity the
1528    support classes for database loading have been moved from the core
1529    osg library into their own osgDB library.  Support for the .osg
1530    ASCII native database format and the .rgb reader has moved into its own
1531    osgPlugins library to further the cleanliness of the core library.
1532
1533    Support has be added for multiple OpenGL context's and hence multi-pipe
1534    systems such as sgi's Onyx2, allowing each context to have its own
1535    display list and texture objects.
1536
1537    The culler and rendering support in osgUtil has also been improved, and
1538    significantly speeded up for complex models.
1539
1540    Also just in, thanks to Randall Hopper for adding support for FreeBSD :-)

1544
1545    >>> Port of OSG to MacOS underway
1546
1547    The first steps towards support of MacOS have been taken by Bryan Woods,
1548    adding Metrowerks project files and adding support for MacOS into the
1549    core scene graph.  Work still in progress so assistance welcome to
1550    complete the task.
1551
1552    Other major developments have been the addition of two new base classes
1553    osg::StateAttribute and osg::Drawable which are designed to allow greater
1554    extensibility of OpenGL state management and primitives.

1558
1559    >>> New 3DS loader added
1560
1561    The OpenSceneGraph now supports the 3DS file format. This makes
1562    available a huge range of potential models. Check out
1563    http://www.3dcafe.com or http://www.3drocketfuel.com for some juice.
1564

1566
1567    >>> Texture compression now supported
1568
1569    The OpenSceneGraph now provides support for ARB and S3TC texture
1570    compression. This allows more textures to be loaded onto graphics
1571    card memory, resulting in happier users and a better world in which
1572    to live.
1573
1574    This release also sees the addition of a simple hang gliding flight sim
1575    demo.
1576

1578
1579    >>> Anisotropic texturing now supported <i>and</i> loading of gzip compressed files
1580
1581    Anisotropic texturing provides for the next step in quality texturing
1582    filtering above tri-linear and is especially effective when viewing
1583    texture surfaces at shallow angles.
1584
1585    Also added in this release is on-the-fly support for loading gzipped
1586    (.osgtgz, .tgz) and zipped (.zip) database files.  This features allows
1587    users to store whole databases (models and textures) in a single
1588    tar ball and unpack them automatically on running the osg.  This
1589    is ideal for browsing the web.

1592
1593    >>> Support added for OpenGL vertex arrays, and several key image loaders.
1594   
1595    Support for OpenGL vertex arrays has been added to improve performance,
1596    particularly accelerating PC based graphics.
1597
1598    Also added is support gif, jpeg, pic, tga, tiff image formats via
1599    dynamic plugins.

1602
1603    >>> New high resolution, low latency timer class - osg::Timer.
1604
1605    Real-time graphics relies upon accurate timers for updating physics
1606    simulations and managing constant framerates.  The OSG now provides
1607    osg::Timer which, when supported, takes advantage of hardware timers.
1608

161018th November 2000 - osg_src-0.8-29.tar.gz
1611
1612    >>> Support for detail drawing with osg::PolygonOffset.
1613
1614    Rendering of polygons which overlay underlying geometry, such
1615    as white lines on a runway, can now be achieved utilizing the
1616    new osg::PolygonOffset which encapsulates glPolygonOffset to
1617    avoid z fighting which otherwise hampers such detailing.
1618
161910th November 2000 - osg_src-0.8-28.tar.gz
1620
1621    >>> New Open Flight .flt loader!
1622
1623    Thanks to Brede Johansen submission of .flt loader, the OSG can now
1624    read Open Flight .flt databases.
1625
16263rd November 2000 - osg_src-0.8-26.tar.gz
1627
1628    >>> Driving and Flight modes have been added to viewers.
1629
1630    osgUtil::DriveManipulator and osgUtil::FlightManipulator have been
1631    added to allow the scene graph viewer (sgv) and other viewers to
1632    support a drive and flying modes.  These modes can be accessed
1633    in sgv by pressing '2' and '3' respectively ('1' returns to
1634    trackball manipulator).  Left mouse button accelerates forward,
1635    middle stops motion and right deccelerates.
