The new viewer architecture also provides support for novel display systems that require distortion correction, such as hemispheres and full domes as well as power-walls and caves. It replaces Producer as a windowing toolkit.
262** osgManipulator - provides a set of interactive manipulators for scaling, rotating and moving objects in the scene.
263** osgShadow - provides an extensible framework for adding dynamic shadows to your scene.
264* New low-level extensible intersection framework that includes support for line, plane and polytope intersections.
265* New high-level intersection classes that support paged databases, [=LineOfSight=], [=HeightAboveTerrain=] and [=ElevationSlice=].
266* View-dependent overlay - provides ability to overlay text, country boundaries etc. directly on to terrain, even paged databases.
267* Plugins
268** Improvements to the [=OpenFlight=], COLLADA, [=AC3D=], DDS plugins and many more
269** New TXF texture font reader.
270** New [=VRML2=] reader (using the [=OpenVRML=] library).
271* Easier 3rd party windowing integration
272** With examples showing integration with GLUT, SDL, Qt, [=WxWidgets=] and MFC
273* External dependencies removed simplifying build and distribution
274** [=OpenThreads=] is moved into the core of [=OpenSceneGraph=] and is no longer an external dependency

306!!![=OpenSceneGraph=] 1.2 release introduces Windows 64bit and AIX support, COLLADA support, processor affinity and texture atlas builder.
307
308PERTHSHIRE, 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.
309
310The [=OpenSceneGraph=]-1.2 release introduces:
311
312* 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.
313* Support for IBM's AIX operating system, bringing the total number of supported operating systems to 8.
314* 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=].
315* 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.
316* 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.
317* 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.
318* A range of bug fixes and API refinements.
319
320The [=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.

431BETA releases
432
43325th May 2005 - OpenSceneGraph-0.9.9
434
435>>> OpenGL Shading Language integrated into core, Introspection, movies, particle effects and much more... 
436
437Introduction to the OpenSceneGraph:
438
439The 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.
440   
441The OpenSceneGraph 0.9.9 release:
442   
443The 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.
444   
445The 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:
446       
447OpenGL Shader Language support:
448   
449OpenGL 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.
450       
451Introspection support:
452   
453The 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
454to 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.
455
456Better support for Apple native Windowing:
457
458Thanks 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.
459   
460Support for latest OpenGL extensions:
461   
462Support for the Non power of two texture feature of OpenGL 2.0 has been added
463to 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.
464   
465Terrain generation and rendering enhancements:
466   
467The 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.
468       
469Particle Effects:
470   
471To 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.
472   
473DXF and Movie plugins:
474   
475A 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.
476   
477Application and examples:
478   
479To 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.
480   
481There 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.
482   
483osgpbuffer also example now uses Producer's pbuffer support making it portable across platforms and much cleaner.
484   
485API refinements, bug fixes and performance improvements:
486   
487There 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.
488   
489We would like to thank the following engineers for their contributions in the 0.9.8 - 0.9.9.9 time frame (in alphabetic order):

517
518    >>> Support for database archives, improved pager, 3d compressed textures
519
520    Release 0.9.8 reflects a continuation of the prior committment to release
521    often, arriving only two short months after 0.9.7.  This contrasts sharply
522    to the long period between 0.9.6-2 and 0.9.7.  The following set of
523    improvements and features are part of the 0.9.8 release.

545   
546
547    New support for 3d texture compression using the
548    GL_NV_texture_compression_vtc extension has been added, providing an
549    improvement on the S3TC compression techniques.
550   
551    The OSG Spelling Bee is making its mark in this release, with submissions
552    by the community to correct spelling and typo errors throughout the osg,
553    osgDB and osgUtil libraries.
554   
555    osgDB::ReaderWriter and osgDB::Registry have been refactored to allow
556    multi-threading of database reading and writing.       
557

583   
584
5859th August 2004 - OpenSceneGraph-0.9.7
586
587    >>> support for and generation of large scale geospatial databases,
588    >>> support for movies and examples of shadows and volume rendering.
589   
590    The 0.9.7 encompasses many improvements, bug fixes, new examples and
591    significant new functionality, the most notable of which is a new
592    osgTerrain library for generation of large scale geospatial databases.
593   
594    The new osgTerrain library and associated osgdem utility program
595    allows users to use moziacs of geospatial imagery and digital elevation
596    maps to generate a complete paged database which can be used with
597    standard OSG viewers, and users programs. By utilising GDAL to load the
598    imagery and DEM's a wide range of geospatial formats are supported.   
599     
600    The TerraPage plugin has also been rewritten ontop of the OSG's
601    osg::PagedLOD and osgDB::DatabasePager which provides support for the
602    tile fallback mechanism to ensure that no holes or cracks appear in the
603    databases being roamed, and to achieve constant frame rate via load
604    balancing mechanisms with osgDB::DatabasePager.
605   
606    The osgDB::DatabasePager has been further improved to provide more
607    configurable load balancing which allows application developers to achieve
608    constant frame rates when using paged databases.
609   
610    Double Vec & Matrix classes & CoordinateSystemNode/EllipsoidModel class
611    have been introduced to better support browsing of large scale databases,
612    and to provide a mechanism for tracking the local up orientation when
613    roaming whole earth databases.
614   
615    osgUtil has been enhanced with:
616     - an improved triangle tipper class (osgUtil::TriStipVisitor),
617     - a new simplifier (osgUtil::Simplifer) for reducing triangle density of
618       osg::Geometry leaves (utilised by osgTerrain to provide simplification
619       of terrain tiles),
620     - improved and more configurable optimizer (osgUtil::Optimizer),
621     - a new utility class for compiling and releasing OpenGL objects
622      (osgUtil::GLObjectVisitor) replaces the previous and more limited
623       DisplayListVisitor.
624   
625    All the osgGA::MatrxManipulator's (used for camera manipulator etc) have
626    been revamped with usage of doubles internally, and with tracking of the
627    current CoordinateSystem if one is active, to be better support whole
628    earth databases.  All the MatrixManipulators have been extend to allow
629    the setting of a user defined home position.  Two new manipulators have
630    been introduced osgGA::TerrainManipulator, for roaming whole earth/terrain
631    databases, and osgGA::TrackerManipulator which allows the camera to be
632    attached to a node in the scene graph.
633
634    Movie support under Linux and OSX via libMpeg3 and Quicktime respectively,
635    which extend the new osg::ImageStream base class which allows application
636    developers access to playing, pausing and rewinding movies.
637
638    The conversion utility osgconv has been extended to allow compression of
639    textures and mipmap generation during conversion when writing to the native
640    .ive binary format.  Texture compression and pre computer mipmaps enable
641    faster loading of databases and lower utilisation of memory resources.

682                          using a Windowing toolkit, in this example using
683                          Producer, but is written so the example could easily
684                          be modified to work with other Windowing toolkit.
685
686        osgkeyboardmouse  adding to keyboard and mouse functionality on the
687                          osgsimple base.

690                          example.
691   
692        osgmovie          an example which creates a quad to render a loaded
693                          movie file with - requires the LibMpeg3 (Linux) or
694                          Quicktime (OSX) plugin to work.
695       
696        osgvolume         an example that reads a stack of 2d images to create
697                          a 3D texture, and creates a scene graph using
698                          standard OSG components (osg::ClipNode,
699                          osg::TexGenNode, osg::Billboard and
700                          osg::TexEnvCombine) to create a per per lit volume.
701
702   
703    Wrapping up the complete 0.9.7 release is a wide range of smaller features
704    enhancement and many bug fixes.
705
706
7072nd October 2003 - OpenSceneGraph-0.9.6-2
708
709    >>> osgFX Special Effects nodekit (for bumping mapping & cartoon effects etc), support for double Matrix traversals,
710    >>> improved build support, thread safety and robustness.
711   
712    The new osgFX nodekit, written by Marco Jez, adds a set of decorator
713    nodes that add can be conveniently added above subgraphs in your scene
714    to add special a range of special rendering effects.  Effects include
715    AnisotopicLight, BumpMapping, Scribe, Specular Highlights and Cartoon
716    rendering.
717   
718    Support for double Matrices has been added with the new Matrixd class,
719    and complimented by the a Matrixf class.  The original Matrix class is
720    now a typedef which can be set to either Matrixf or Matrixd (which is
721    now the default),  When the Matrix typedef is set to Matrixd and the OSG and
722    dependent apps are recompiled all internal operations such a cull traversals
723    will now be double with double matrices which much improved numerical
724    precision, making it ideal for datasets where a large values are contained
725    with transforms in the scene graph (such as with whole earth databases),
726    and when a transforms are nested which creates requires concatenation of
727    a number of matrices to get the final model view matrices. 
728   
729    The osgGA::MatrixManipulators (which are used to control the camera
730    position) and osgProducer/OpenProducer have been moved across to using
731    exclusively double Matrices.  This has been done to improve numerical
732    precision when computing camera positions, whilst having little impact
733    on performance since camera operations are only done a small number of
734    times per frame.
735   
736    osg::Quat now supports doubles by default, but also allows users to select
737    float version osg::Quat simply by changing the osg::Quat::value_type typedef.
738   
739    Work has been on OpenThreads and OpenProducer, in particular to improve
740    thread safety and robustness on the Win32 platform.  Reported crashes
741    on exit from osgProducer::Viewer based apps, and freezes during runtime
742    have been fixed.
743   
744    Threading problems which caused crashes in recent updates of the Terrapage
745    loader have also been fixed, and additional internal changes have been made
746    to improve the Terrapage loader's ability to hit constant frame rates.   
747    Support has also been added for loading light points directly from the
748    Terrapage database.
749
750    A new .iv/.wrl loader plugin, written by Vivek Rajan, at Magic Earth,
751    has been added to the distribution which uses with OpenInventor or Coin
752    to load model, converting them into OSG equivalents.  Coin has support
753    for VRML97 models, so can be used to import such models into the OSG. 
754    Since the new plugin is dependent on OpenInventor or Coin the compilation
755    is optional, but off by default. To compile this plugin under Unix, set
756    the environmental variable USE_INVENTOR or USE_COIN and recompile. 
757    Windows .dsp project file does to current exist, but should be
758    possible to add this.
759   
760    The .ive plugin has been improved with the addition of support for
761    osgSim light points, and various internal refinements to make it function
762    better on the various platforms supported by the OSG.  Note, these changes
763    mean that the .ive format has has changed and is no longer compatible
764    with previous version of .ive. It is recommend that one recreates .ive
765    for the original source via osgconv or similar to ensure consistency.
766
767    A JPEG2000 image plugin has added, written by Michael Gronager.  The new jp2
768    plugin uses the japser open source project to read and write JPEG2000 files.
769   
770    A scalar bar, and sphere segment helper classes have been added to osgSim,
771    the new osgscalarbar and osgspheresegment examples demonstrate how to use
772    these new features.
773   
774    To help handle running applications of graphics cards/drivers that exhibit
775    bugs with certain OpenGL extensions, support has been added to the GLextensions
776    code to allow extensions to be disabled via the new
777    osg::setGLExtensionDisableString(std::string) function or by setting an
778    OSG_GL_EXTENSION_DISABLE environmental variables.  Follows is an example of
779    the disable string:
780   
781        set OSG_GL_EXTENSION_DISABLE =
782             "ATI:GL_SGIS_generate_mipmap;Sun:GL_EXT_texture_filter_anisotropic:"
783
784    New examples include:
785   
786        osgforest - an example which demonstrates simple techniques for creating forests   
787        osgfxbrowser - an example which demonstrates the various osgFX Effects available   
788        osgscalabar - an example of how to set up the osgSim::ScalarBar.
789        osgspheresegment - an example of how to set up the osgSim::SphereSegement
790        osgpagelod - a very simply test program for setting up osg::PagedLOD/osgDB::DatabasePager
791   
79223rd July 2003 - OpenSceneGraph-0.9.5
793
794    >>> Support added for OpenGL2.0 shaders, native multi-threaded Database paging,
795    >>> high peformance binary format reading and writing,  .dds compressed image
796    >>> loader and ARB_fragment_program and ARB_vertex_buffer_object extensions,
797    >>> improvements to the Terrex .txp and OpenFlight .flt loaders.
798
799    The key new features of the 0.9.5 release are the new OpenGL2.0 nodekit, constant frame rate
800    database paging support,  classes,  and the new native .ive binary plugin which supports
801    both reading and writing of all core osg nodes, including inlining of compressed
802    and non-compressed imagery.
803   
804    The native database paging support, provided by the new osg::PageLOD and osgDB::DatabasePager,
805    achieves constant frame rate through threading of the database reading, and time based
806    incremental compile and delete of display lists, vertex_buffer_objects and texture objects.
807    A new TextureObjectManager class also caches a list of expired texture objects for reuse,
808    and allows new newly loading imagery to reuse expired texture objects, with the imagery
809    automatically subloaded to the reused texture objects.  This reuse happens transparently
810    and benefits other OSG usages such as the OSG's Terrapage loader.
811   
812    To provide support multi-thread operation of the OSG, such as multi-thread database paging
813    and multi-threaded, multi-window graphics enabled by OpenProducer, the OpenSceneGraph and
814    OpenProducer have now adopted the OpenThreads threading library, osgDB and osgProducer now
815    depend upon it.  OpenThreads is open source, light weight, cross platform C++ threading
816    which encapsulates the low level, platform specific threading API calls.  Currently pthreads
817    under Unix and Win32 threads under Windows are supported, with Sgi sproc threads to be
818    released very soon.  The OpenThreads project website can be found at http://openthreads.sf.net.   
819
820    The new .ive binary plugin was developed by Uni-C's VR-Center, and kindly submitted as
821    open source, adds support for binary reading and writing OSG nodes drawable and state
822    (including compressed/mipmapped) textures.  The .ive format produces a much faster
823    load times and smaller file size then native ASCII .osg format. Load times for .ive
824    files are also 10-20x faster then equivalent OpenFlight .flt and load in an already
825    optimized scene graph form making it much more suitable for paging.  Files can be
826    converted easily using the osgconv utility : osgconv myfile.flt myfile.ive
827   
828    The new osgGL2 nodekit library adds support for the OpenGL2.0 vertex ProgramObect and fragment
829    ShaderObject's recently ratified by the OpenGL ARB, . The osgGL2 uses the extension have local
830    prototypes which allow them to be compiled even in the absence of OpenGL headers that don't
831    support the GL2 extension, allowing to port to all platform, and at runtime the extensions are
832    queried for and used if available.  At time of release only 3DLabs WildcatVP series supported
833    this extension at runtime, but other graphics cards and manufactures will be releasing GL2
834    extension very soon and will be automatically supported by osgGL2. The osgGL2 was developed
835    by Mike Weiblen at 3DLabs whom have kindly submitted osgGL2 as open source and for inclusion
836    with the OSG distribution. 
837
838    The ARB_fragment_program, ARB_vertex_buffer_object and ARB_vertex_program attributes are
839    also now supported in core osg library.  The new osg::FragmentProgram state attribute
840    encapsulates the ARB_fragment_program which is supported by the recent graphics cards
841    from NVidia, ATI and 3DLabs.  Support for ARB_vertex_buffer_object and ARB_vertex_program
842    attributes have been added to the osg::Geometry class.  The ARB_vertex_buffer_object extension
843    can boost performance by as much as 50% when working on geometry bound data sets.
844
845    Two new image loaders, dds and pnm, and a 3dc point cloud have been added. The .dds plugin
846    adds support for compressed & mipped mapped imagery, making it ideal for applications where
847    large texture sizes or database paging is required. The pnm image loader reads the
848    pnm, pgm and pbm image formats. See http://netghost.narod.ru/gff/vendspec/pbm/ for details.
849
850    The Terrapage .txp plugin  been updated to include support for multi-texturing, layers and billboards
851    and includes improvements to multi-threaded pager, which has also been ported over to use OpenThreads.
852    The OpenFlight .flt plugin has also been improved and now support detail textures via multi-texturing.
853
854    TessellationHints now supported by ShapeDrawable which allow the shape primitives to be rendered
855    are vary levels of detail.
856
857    Supported has been added for auto scaling and rotating text into osgText.
858
859    Five new examples have been included in the distribution:
860   
861        osgtexturerectangle illustrates how to use the osg::TextureRectangle which encapsulates
862        the NV_texture_rectangle extension.
863       
864        osgprerendercubemap illustrates how to use pre rendering imagery to osg::TextureCubeMap
865        for tasks such as building a environmental texture maps.
866       
867        slideshow3D is a presentation tool which use a scene graph to store a render set of slides, each
868        slide containing layers which can contain bullet points, paragraph, imagery and 3d animated
869        models - and is effectively a 3D power point. The presentations can be built separately and stored in a .osg file or created by
870        slideshow3D via an xml file, two examples - introduction.xml and models.xml, which are included
871        in the OpenSceneGraph-Data-0.9.5 data distribution.  slideshow3D depends upon libxml2 for parsing
872        the xml files.
873       
874        osgpoints uses the osg::Point state attribute to attenuate and control point size and any points
875        loaded by the application.  This is a useful way of visualizing point data clouds.
876       
877        osgdemeter is example of how to integrate the Demeter, OSG using osgProducer::Viewer as a viewer
878        class.  This example depends upon the demeter terrain engine, which can be download from
879        http://www.terrainengine.com.
880
881    Camera style convenience set and get methods to osgUtil::SceneView, consolidating
882    previous functionality that was provided by both osg::SceneView and osg::Camara into one place.
883    This move has made osg::Camera redundant so has it been removed to avoid confusion,
884    usage inconsistencies and bloat of core libraries.
885   
886    The long time deprecated osg::GeoSet has been removed, to aid migration of old .osg datasets
887    osgconv has a copy of GeoSet and the .osg support for it so is able to convert any remaining
888    .osg database which contained GeoSet's.
889
890   
891
89228th April 2003  - OpenSceneGraph-0.9.4-2
893
894    >>> Multi-threaded, multi-pipe support via integration with OpenProducer,
895    >>> 64bit Linux support for Intel Intanium and AMD Opteron,
896    >>> new osgText library with greater performance, and thread safety,
897    >>> new DDS plug-in for compressed and non-compressed images,
898    >>> new MD2 plug-in adds support for animate Quake character and
899    >>> support added for NV_texture_rectangle.
900
901    The most significant new feature is the osgProducer library that adds
902    tight integration with OpenProducer, providing the OpenSceneGraph with a
903    scalable, configurable and portable framework for developing real-time
904    and interactive graphics applications.  The scalability afforded by
905    OpenProducer allows applications to be developed which run seamlessly
906    on single pipe machines up to multi-pipe machines such as Sgi Onyx
907    IR system, and Sun Zulu systems.
908    The osgProducer/OpenProducer framework automatically handles the
909    multi-threading of cull-draw pairs and GUI events.
910
911    All the example programs have been ported over from being based on
912    GLUT to using osgProducer (osgGLUT can now be found in the bazaar
913    section on the website). The move to osgProducer allows all the examples
914    to scale from running on laptops up to multiple CPU and graphics pipe systems.
915    The configuration of threading and multiple camera views can all be done
916    via ASCII configuration files, no need to recompile.  A number of
917    new examples have also been added or revamped, bringing the total to 42.
918
919    Also in the theme of increasing scalability there is support for 64bit Linux for both
920    IA64 (Intel Itanium) and x86-64 (AMD Opteron) which compliments the existing
921    support for Solaris and IRIX 64 bit compilation.  64 bit supports allows
922    the use of very large data sets, and potential performance improvements.
923
924    To help support development teams working with multiple build configuration,
925    the makefile system has been extended to allow multiple build targets to be
926    built from one source code base.  All makefiles are also now named GNUmakefile
927    which ensures that they are only run by gmake to avoid an confusion on system
928    where gmake isn't the default make tool.
929
930    A completely new osgText implemention has been developed which is simpler
931    to use, faster, and thread safe.  Support for high quality true type fonts
932    has now been moved to a freetype plug-in which is dynamically loaded on demand,
933    with the core osgText library providing a default font when the plug-in is
934    unavailable.  Moving the freetype dependency out of the osgText library makes
935    it just dependant on OpenGL and Standard C++ like the rest of the core libraries,
936    allowing osgText to compile by default on all platforms.
937
938    Improved thread safety has also been achieved in the core osg and osgUtil libraries
939    making work on multiple CPU/multi-pipe systems robust and with improved performance.
940
941    Two new plug-ins have been added, for loading DDS and MD2 data formats. The DDS plug-in
942    is for loading compressed and non-compressed images.  The MD2 plug-in loads Quake
943    animated characters.
944   
945    osg::TextureRectangle class has been added, which encapsulates the
946    NV_texture_rectangle and EXT_texture_rectangle extensions.  This is particularly
947    useful for render to texture algorithms, and dynamic paging of images such as for
948    rendering video streams.
949
950    Support for automatic subloading of osg::Texture2D textures has been added
951    so that when image data is updated the corresponding OpenGL texture is
952    automatically updated - no need for callbacks.  Also added to the osg::Texture
953    classes is the option of automatic unref'ing of texture image data once the data has
954    been download to all active OpenGL graphics contexts.
955   
956    A new osgUtil::DelaunayTriangulator utility class has been added.  This is ideal for
957    creating optimal triangular meshes from unconnected data points.
958
959    Two new classes, osg::ArgumentParser and osg::ApplicationUsage, have been introduced
960    to convineiently and robustly parse command line arguments and
961    report command line usage, environmental variables and keyboard and mouse bindings
962    used by applications.  Running any of the examples with -h or --help will report
963    full details example usage.  Keyboard and Mouse bindings usage is now also available as
964    a HUD on all examples, simply press 'h' while the app is running to
965    bring up help.
966
967    A database cache in the osgDB library has been added, along with a clean up
968    of memory management in the OpenFlight loader, make development of
969    dynamic paging of databases easier and more robust.
970   
971    Support for early abort of rendering has been added, which is useful for
972    interactive applications which occasionally have rendering that takes that long
973    enough (i.e.several seconds) that end users may wish to abort during the drawing.
974
975    There have also been many general API improvements and bug fixes, too many to enumerate,
976    but all go to solidify the quality of the scene graph and its accompanying libraries. 
977   
978    The combination of new features, robustness and scalability mark this release as a
979    significant step towards 1.0.

989
990    Added osgProducer library which integrates the OpenSceneGraph seemlessly
991    with OpenProducer to provide runtime configurable management of windows
992    and multipipe graphic systems.  The osgproducer demo illustrate how
993    developers can write applications very simply that harness the power
994    of the OpenProducer and OpenSceneGraph in an extremely flexible way.
995    OpenProducer can be downloaded from:
996    http://www.andesengineering.com/BlueMarbleViewer/producer_install.html
997
998    Support added for dynamic paging of Terrage databases, the required
999    multi-threading is set up by defult.  All the end user application need
1000    to do is load the database and the paging then happens automatically -
1001    without any need for intervention by the users application.
1002
1003    Addition of osgSim which is NodeKit designed for visual simulation
1004    market, currently features high fidelity light points support.  Light
1005    point sectors, blink sequences and groups, and light point fading are
1006    all supported.
1007

1019    New osglogo demo - features anti-aliased TrueType text and animation.
1020   
1021    The app phase of operations on the scene graph has been renamed
1022    the update phase to make its function clearer. The main phases are now
1023    named now does update, cull, draw.  The AppVisitor, set/getAppCallback etc
1024    have be renamed UpdateVisitor, set/getUpdateCallback etc.
1025
1026    Removed the osg/ManagerManger and associated #define osgNew's, this has
1027    been done to simplify users code and to solve the lack of thread safety
1028    that was causing problems with the MemoryManager.
1029   
1030    Support added for reading and writing of callbacks in the .osg format.
1031   
1032    Support added for reading and writing of osg::Shapes in the .osg format.

1051    each LOD child, bringing it inline with the OpenFlight style LOD
1052    representation.
1053
1054    Switch has been revamped to allow independent switching on or off of
1055    each Switch child, bringing it inline with the OpenFlight style Switch
1056    representation.
1057
1058    New osg::Shape geometry primitives added which allow the specification
1059    of geometry in a form that can accelerate collision detection, and as
1060    a way of specifying the geometry to tessellate.  Shapes include
1061    Sphere, Oriented Box, Cone, Cylinder, Grid, TriangleMesh, ConvexHull
1062    and CompositeShape which allows the storage of a hierarchy of shapes.
1063   
1064    Geometry has been extended to all per primitive bindings and
1065    per primitive set bindings of attributes, and indexing of attributes
1066    with the same or different index lists for each attribute list.
1067
1068    From Macro Jez, new cubemap helper classes.
1069
1070    Support added for handling different extensions on different graphics
1071    contexts.
1072
1073    Draw and Sort callbacks added to osg::RenderStage.
1074
1075    Added PolygonStipple class.
1076   
1077    Further refinement of class names and method calls:
1078    Renamed classes :
1079   
1080        Primitive    -> PrimitiveSet
1081       
1082    Renamed methods :
1083   
1084        Geometry::addPrimitive(..) -> addPrimitiveSet(..)
1085        Drawable::drawImmediateMode(..) -> drawImplementation(..) const
1086        Drawable::DrawCallback::drawImmediateMode(..) -> drawImplementation(..) const

108930th August 2002 - OpenSceneGraph-0.9.1.tar.gz
1090
1091    >>> 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!
1092
1093    Despite only 6 weeks passing between 0.9.0 and this latest 0.9.1 release
1094    there has been a number of significant new features, API clean ups and
1095    bug fixes.  Follows is a quick run through the key improvements.
1096
1097    Addition of osg::Texture1D, Texture2D & Texture3D classes, Texture2D replaces
1098    the original osg::Texture, which has now become a pure virtual base class. All
1099    Texture classes, including TextureCubeMap are derived from this base class..
1100   
1101    New osgtexture1D and osgtexture3D demos demonstrate the new texture classes in
1102    action.
1103   
1104    The build system has been updated to support HP-UX.  This adds one of the last
1105    remaining mainstream platforms supported.
1106
1107    A new Inventor/VRML1.0 loader was added.  The inventor format has been requested
1108    on numerous occasions, so this is a welcome addition.
1109   
1110    Support added to lwo plugin for loading the new lwo2 format.
1111
1112    osg::TexEnvCombine implemented texture_env_combine and texture_env_crossbar
1113    and texture_env_dot3 extensions.
1114
1115    osg::TexEnv texture_env_add added.
1116
1117    A osg::Sequence node has finally been implemented.  It is accompanied by a
1118    demo, osgsequence.
1119
1120    osg::DOFTransformNode implemented.
1121
1122    Support for OpenFlight15.7 added, DOFTransforms and general enhancements and
1123    bug fixes.
1124
1125    New PROTECTED mode for protecting local state mode and attributes from be
1126    overridden from state above it in the scene graph.
1127   
1128    Support for fog coord and secondary colors extensions added to osg::Geometry.
1129
1130    osg::Billboard has been improved to allow rotations around all axes, as well
1131    as point rotations.  Check osgbillboard for a new improved demo.
1132
1133    The osglight example has been improved by utilizing AnimationPath and
1134    PositionAttitudeTransform to keep light sources in motion.
1135
1136    osg::AnimationPath improved, now allowing swing and looping behavior and
1137    with two new app callbacks which can update PositionAttitudeTransform
1138    and MatrixTransform respectively.
1139   
1140    Support for writing osg::Image's to .rgb format added.
1141
1142    To keep the overall API clean, and the following items have been
1143    renamed and deprecated parts of the API have been removed:
1144
1145    Renamed classes:
1146
1147            EarthSky        -> ClearNode
1148            Transparency    -> BlendFunc
1149            Texture         -> Texture2D  (old style subload parameters removed)
1150
1151    Method's changed
1152
1153            Matrix          -> makeRotate(..) euler angles parameters generalized.
1154            Quat            -> makeRotate(..) euler angles parameters generalized.
1155
1156            BoundingBox     -> isValid() renamed valid()
1157            BoundingSphere  -> isValid() renamed valid()
1158
1159            StateAttribute  -> OVERRIDE_OFF & OVERRIDE_ON which were short hand
1160                               versions of OVERRIDE | OFF and OVERRIDE | ON
1161                               removed, as the meaning of the bitmask was
1162                               often confused by the short hand notation.
1163
1164
1165            Transform       -> setMatrix/getMatrix() etc methods removed,
1166                               Transform becoming the transform base class,
1167                               with MatrixTransform taking over all the original
1168                               functionality.
1169

117119th July 2002 - OpenSceneGraph-0.9.0.tar.gz
1172
1173    >>> OpenSceneGraph goes beta - Multitexturing, Occlusion Culling, Particles and much more added!
1174
1175    This release marks the beginning of the beta phase of the OpenSceneGraph
1176    development, which means that all the major core features are now
1177    in the scene graph, and 1.0 is not far away.  Its performance, features
1178    and portability already compares very favorably to other scene graphs,
1179    both comerical and open source. 
1180
1181    Multi-texturing support added to osg::StateSet, osg::Geometry, osg::State
1182    and txp loader, so multi-texturing can now be done with very little coding
1183    from the user - all you need to do is specify the texture unit to use
1184    when setting texturing state and texture coordinates and the rest is
1185    handled automatically by the scene graph!
1186   
1187    The new osg::Geometry classes which supersedes the old Performer style
1188    osg::GeoSet, support multi-texturing, and uses sharable osg::Arrays which
1189    utilize std::vector<> for data storage and manipulation.
1190
1191    Shadow volume occlusion culling adding to the core OSG, developed as a
1192    collobaration between Mike Connell and Robert Osfield. Our implementation
1193    uses convex planer occluders, with support for holes to allow larger
1194    and more effective occluders to be used. The approach is software
1195    based so it 100% portable, and by culling during the cull traversal
1196    both CPU and GPU loads are significantly reduced, making it an extremely
1197    powerful feature for large scale urban and indoor visulisation.
1198
1199    osgParticle developed by Marco Jez adds support for a range of particle
1200    effects such smoke, fires, engine plumes, fountains, fire works, and
1201    is fully customizable to produce your own favorite effects. osgParticle
1202    is a NodeKit (see below) which can be directly linked to in your
1203    application to allow you to create particle effects by hand, or have
1204    the library dynamically loaded in when you load a database which contains
1205    particle effects.
1206   
1207    osgGA (Gui Abstraction) library written by Neil Salter adds classes for
1208    adapting different GUI toolkits to work with a standard set of manipulators for
1209    modifying the scene, such as camera and state manipulators.
1210   
1211    Support has been added to the plugin architecture to facilitate the
1212    development of NodeKits - add on libraries which can used directly
1213    in your code, or loaded indirectly when loading from file.  The
1214    later allows you to load a .osg file with text or particle effects
1215    in them,the plugin architecture automatically loads the required
1216    library which supports these features.
1217
1218    A range of new demos have been as code examples, and to demonstrate
1219    the range of features that OpenSceneGraph delivers:
1220
1221        osgoccluder  - demonstrates ocllusion culling, and has a mode
1222                       which allows the users to interactively create
1223                       their own convex planer occluders.
1224        osghud       - how to mix head up display with 3d views.
1225        osgparticle  - shows the new osgParticle node kit in action.               
1226        osgprerender - pre renders and scene then textures the result onto
1227                       an animated flag.
1228        osgcallback  - examples of the full range of callbacks that you
1229                       can use to add dynamic behaviors to your scene graph.
1230        osglight     - a simple example of how to set up spot and position
1231                       lights in the scene.
1232        osgclip      - illustrates how to add clip planes to you scene.
1233        osggeometry  - examples of the different ways to set up primitives
1234                       and vertex/color/normal and texture attributes in
1235                       the new osg::Geometry class.
1236        osgmultitexture - a simple example which adds a spherical reflection
1237                        map to a whole scene using the second texture unit
1238                        if one exists.
1239       
1240    osg::Drawable::PrimtiveFunctor has also been added to allow querrying
1241    of primitive data with Drawables subclasses without requiring knowledge
1242    of the types of Drawable subclasses that exists.  This decoupling makes
1243    it a very powerful and flexible utility.
1244
1245
124626th April 2002 - OpenSceneGraph-0.8.45.tar.gz
1247
1248    >>> Support added for Solaris, texture cube mapping & muliple projections.
1249   
1250    The OpenSceneGraph now has a new Makefile system which supports all Unix
1251    compilation including the new addition to the family - Solaris! 
1252
1253    OpenSceneGraph welcomes Solaris to the list of supported platforms.  This
1254    release puts all of the OpenSceneGraph functionality at the fingertips of
1255    Sun Microsystem's customers and developers.  Solaris users can now have
1256    the benefit of a high performance scene graph for visual simulation,
1257    virtual reality, scientific visualization, CAD, and architectural
1258    walk-throughs.  Many thanks to Sun for providing resources for the port.
1259   
1260    Additional html documentation has been added to the distribution to
1261    make it easier to get an understanding of scene graph technology and
1262    the project itself and how to make use of it. 
1263
1264    Support has also been added for OpenGL's texture cube mapping which
1265    is ideal for accurate environmental reflections and much more.
1266   
1267    The scene graph has been extended to allow multiple projection (via
1268    the new osg::Projection node) and viewports within one scene graphs,
1269    this makes it much easier to set up head up displays, and we have
1270    an example to demonstrate how easy it is - osghud.
1271   
1272    The osgUtil::CullVisitor and osgUtil::SceneView has been revamped
1273    removing the dependency on osg::Camera, which is now simply an
1274    option for SceneView rather than a requirement.  This allows users
1275    to set the camera entirely with the scene graph or create their own
1276    camera classes and use them with SceneView.  The existing osg::Camera
1277    has also been simplified as support for setting projection and
1278    modelview matrices have been moved out to the cull traversal.
1279   
1280    Several sets of node callbacks have been added, including a Cull
1281    NodeCallback on each Node, ComputeTransformCallback on Transform
1282    Nodes, EvaluateLODCallback on LOD nodes, ComputeBillboardCallback
1283    on Billboard nodes.  These make it my easier to customize the
1284    scene graphs behavior at runtime.
1285   
1286    osg::Image::readPixels() and support for writing .bmp files has been
1287    added which has made it easy to add screen capture the any OpenSceneGraph
1288    application.  This feature is demonstrated in the scene graph viewer
1289    which comes with the distribution - just press 'O' to output a screenshot.
1290   
1291    Finally, include/osg/MemoryManager has been added which overrides new
1292    and delete for debug builds. The override new and delete track allocations
1293    and deallocations, ensure they are matched, checked for memory under and
1294    overruns, and outputs a memleaks.log file on the results of executing
1295    your applications.  This help track down a number of memory leaks and
1296    unmatched new and deletes within the OpenSceneGraph and should make
1297    it easier to do with users applications as well.
1298   
1299    All in all, the OpenSceneGraph is now more portable, easier to
1300    customize, cleaner and more robust.  Beta release and 1.0 is now not
1301    far away!
1302   
1303
130424th February 2002 - osg-0.8.44.tar.gzosg-
1305
1306    >>> Support added for Mac OSX, Cygwin and MinGW, and new TerraPage loader.
1307   
1308    The major item for this release is the completion of the Mac OSX port,
1309    thanks to Phil Atkin and others for making this happen.
1310   
1311    Also added to support for Cygwin and MinGW builds which gives Windows
1312    users a free and robust alternative to the Visual C++, which we
1313    have Norman Vine to thank.
1314   
1315    Funtionality wise there has been a great deal of work behind the scenes
1316    putting in place a flexible and extensible framework for handling
1317    transform nodes, users can now extend the osg::Transform node through
1318    subclassing or via callbacks.  This work will underpin future work
1319    on moving camera setup into the scene graph, and environmental effects
1320    such as cloud layers, ground planes, stars and earth sky implementations
1321    which are planned for the next release.
1322   
1323    Callbacks and virtual methods have also been added to the osg::LOD &
1324    osg::Billboard to allow users to customize their behavior.  Draw
1325    callbacks have also been added to allow customization of osg::Drawables
1326    at runtime.
1327   
1328    The Open Flight .flt loader has undergone a number of improvements
1329    including support for instancing and billboards.
1330   
1331    New TerraPage (.txp) loader and OpenDX writer (.dx) plugins have been added.
1332   
1333    Support for the clone operation on osg::Object's has been expanded
1334    to allow cloneType() - a simple clone an blank object of the same type,
1335    and clone(CopyOp&) where CopyOp is a functor which allows users to
1336    specify the deep copy vs shallow copying of object data.
1337   
1338
13392nd January 2002 - osg-0.8.43.tar.gz
1340
1341    >>> Support for TrueType text, Stereo out of the box, and much more.
1342   
1343    Since the last release the OSG has moved to CVS based developments so
1344    many users will have seen gradual increments in functionality and changes
1345    to the API. Whereas a the leap from 0.8.42 to 0.8.43 is actually quite
1346    significant is likely to require code changes as several significant parts
1347    of the API have evolved to a more mature state.
1348   
1349    The most significant new functionality is the addition of the osgText
1350    library which provides support for true type font rendering, as textured,
1351    polygonal, pixmap, bitmap and 3D fonts.
1352   
1353    We now have new osg::Matrix implementation which cleans up its interface.
1354    Also all angular parameters are now based on radians rather than degrees
1355    as before (and as in Performer), this has been done to be more consistent
1356    with the basic trignometric functions and standard maths conventions.
1357   
1358    Scene graph optimization has been added which can boost performance
1359    on some database by as much as an order of magnititude, this is
1360    particularily noticable in .flt based databases.  Display list performance
1361    has also been boosted on NVidia based machines thanks to changing the
1362    compilation and execution of display list into two seperate operations.
1363   
1364    App callbacks are now supported on all Nodes, and there now a proper
1365    app traversal which can be used to animate the scene.
1366   
1367    Stereo support has been added into the osgUtil::SceneView which allows
1368    quad buffered/anaglyphic stereo to enabled easily for almost all OSG
1369    applications without code modifications - simple set environmental
1370    variable or pass in appropriate arguments and your app will render in
1371    stereo!
1372
1373    src/Demos/osgcluster has been added to demonstrate how easy it is
1374    to set up a graphics cluster across a standard networked PC's.
1375
1376    There have been many minor code changes to fix bugs and address
1377    performance bottlenecks or to improve extensibility was, representing
1378    a significant step towards API maturity and a beta release which is
1379    now not far away.
1380
1381
13829th August 2001 - osg-0.8.42.tar.gz
1383
1384    >>> New osgWX library for integration of OSG with wxWindows apps.
1385
1386    This release sees a relatively minor number of enhancements over
1387    0.8.41, the most significant being the new osgWX library and wxsgv
1388    demo written by Ben Discoe.
1389   
1390    Also from Brede Johansen in this release is the improvements in support for older
1391    .flt (Open Flight) files such versions 12 & 13.  Previously only version
1392    15.6 files had been tested and developed to.
1393   
1394    Last but by no means least, several bug fixes related to view frustum
1395    culling have been made.
1396
1397
139825th July 2001 - osg-0.8.41.tar.gz
1399
1400    >>> Support added for multi-pass and multi-stage rendering including Impostors.
1401
1402    The key feature developed is a highly flexible framework for multi-pass and
1403    multi-stage rendering techniques.  Unlike most scene graphs and games
1404    engines the OSG has as dynamic framework which automatically configures
1405    itself at runtime.
1406
1407    Building ontop of the new framework's multi-stage rendering capabilities,
1408    support for Impostors (hirachical image caching) has been integrated into
1409    the core scene graph  library making extremely easy to take advantage of
1410    this advanced rendering techinque - normally only seen in research papers.
1411    Check out osgimpostor demo to see how easy it is to add osg::Impostor
1412    nodes to your own models. Impostors are particularily effective are
1413    reducing scene complexity whilest minimizing the visual impact, making it
1414    ideal for scenes with large numbers of complex objects such as a city
1415    scene, or a dense forest.
1416   
1417    Taking advantage of the new framework's multi-pass rendering capabilities
1418    is osgreflect demo which illustrates how to achieve planar relfections
1419    using the stencil buffer and multi-pass rendering.
1420   
1421    The cool thing about both the osgreflect and osgimpostor demos is that
1422    there is no hardwiring to achieve the results, the scene graph stores
1423    all the information neccessary to specify the number and type of rendering
1424    passes, and the framework handles the rest behind the scenes.  This also
1425    makes it very easy to add these advanced rendering techinques to your
1426    own applications as everything is cleanly encapsulated with
1427    osgUtil::SceneView.
1428
1429    New loaders have been added to support .lwo (Light Wave), .obj
1430    (Alias Wavefront) and .dw (Design Workshop) 3D file formats making it
1431    even easier to compose your own worlds from models sourced from the
1432    web or your own.
1433   
1434    osg::Camera has been totally revamped and now supports asymetric
1435    and othographics projections in addition to the symetrical perspective
1436    projections.
1437
1438    And finally, support for texture subloading has been added to osg::Texture
1439    and osg::Image.  This allows textures to be updated dynamically, and
1440    has already been used for mpeg video playback!   
1441
1442
144319th May 2001 - osg-0.8.40.tar.gz
1444
1445    >>> Project lead, Robert Osfield, makes full-time commitment to OSG.
1446
1447    This is the first full release since project lead, Robert Osfield, made
1448    a move to pursue the OSG's development full-time.  This commitment has
1449    been made to bring the API rapidly towards maturity, and to provide
1450    high quality support and consultancy services.  Please contact
1451    robert@openscenegraph.com if you have any queries.
1452
1453    This release marks a significant step forward in the maturity of the
1454    API, with several major changes to the library in the areas of state
1455    handling, database support, and portability.
1456
1457    To improve the extensibility of the OSG's handling of OpenGL state,
1458    new classes have been introduced to replace the previous hardwired
1459    state handling classes.  The new classes also allow improved state
1460    sorting and lazy state updating which boosts both cull traversal
1461    and particularly draw traversal performance.
1462
1463    To improve the modularity, interopability and conceptual clarity the
1464    support classes for database loading have been moved from the core
1465    osg library into their own osgDB library.  Support for the .osg
1466    ASCII native database format and the .rgb reader has moved into its own
1467    osgPlugins library to further the cleanliness of the core library.
1468
1469    Support has be added for multiple OpenGL context's and hence multi-pipe
1470    systems such as sgi's Onyx2, allowing each context to have its own
1471    display list and texture objects.
1472
1473    The culler and rendering support in osgUtil has also been improved, and
1474    significantly speeded up for complex models.
1475
1476    Also just in, thanks to Randall Hopper for adding support for FreeBSD :-)

1480
1481    >>> Port of OSG to MacOS underway
1482
1483    The first steps towards support of MacOS have been taken by Bryan Woods,
1484    adding Metrowerks project files and adding support for MacOS into the
1485    core scene graph.  Work still in progress so assistance welcome to
1486    complete the task.
1487
1488    Other major developments have been the addition of two new base classes
1489    osg::StateAttribute and osg::Drawable which are designed to allow greater
1490    extensibility of OpenGL state management and primitives.

1494
1495    >>> New 3DS loader added
1496
1497    The OpenSceneGraph now supports the 3DS file format. This makes
1498    available a huge range of potential models. Check out
1499    http://www.3dcafe.com or http://www.3drocketfuel.com for some juice.

1502
1503    >>> Texture compression now supported
1504
1505    The OpenSceneGraph now provides support for ARB and S3TC texture
1506    compression. This allows more textures to be loaded onto graphics
1507    card memory, resulting in happier users and a better world in which
1508    to live.
1509
1510    This release also sees the addition of a simple hang gliding flight sim
1511    demo.

1514
1515    >>> Anisotropic texturing now supported <i>and</i> loading of gzip compressed files
1516
1517    Anisotropic texturing provides for the next step in quality texturing
1518    filtering above tri-linear and is especially effective when viewing
1519    texture surfaces at shallow angles.
1520
1521    Also added in this release is on-the-fly support for loading gzipped
1522    (.osgtgz, .tgz) and zipped (.zip) database files.  This features allows
1523    users to store whole databases (models and textures) in a single
1524    tar ball and unpack them automatically on running the osg.  This
1525    is ideal for browsing the web.

1528
1529    >>> Support added for OpenGL vertex arrays, and several key image loaders.
1530   
1531    Support for OpenGL vertex arrays has been added to improve performance,
1532    particularly accelerating PC based graphics.
1533
1534    Also added is support gif, jpeg, pic, tga, tiff image formats via
1535    dynamic plugins.
1536

1538
1539    >>> New high resolution, low latency timer class - osg::Timer.
1540
1541    Real-time graphics relies upon accurate timers for updating physics
1542    simulations and managing constant framerates.  The OSG now provides
1543    osg::Timer which, when supported, takes advantage of hardware timers.
1544

1547
1548    >>> Support for detail drawing with osg::PolygonOffset.
1549
1550    Rendering of polygons which overlay underlying geometry, such
1551    as white lines on a runway, can now be achieved utilizing the
1552    new osg::PolygonOffset which encapsulates glPolygonOffset to
1553    avoid z fighting which otherwise hampers such detailing.
1554
155510th November 2000 - osg_src-0.8-28.tar.gz
1556
1557    >>> New Open Flight .flt loader!
1558
1559    Thanks to Brede Johansen submission of .flt loader, the OSG can now
1560    read Open Flight .flt databases.
1561
15623rd November 2000 - osg_src-0.8-26.tar.gz
1563
1564    >>> Driving and Flight modes have been added to viewers.
1565
1566    osgUtil::DriveManipulator and osgUtil::FlightManipulator have been
1567    added to allow the scene graph viewer (sgv) and other viewers to
1568    support a drive and flying modes.  These modes can be accessed
1569    in sgv by pressing '2' and '3' respectively ('1' returns to
1570    trackball manipulator).  Left mouse button accelerates forward,
1571    middle stops motion and right deccelerates.
