[=OpenSceneGraph=] 2.0, 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=] 2.0 runs on all Microsoft Windows platforms, Apple OS/X, GNU/Linux, IRIX, Solaris, HP-UX, AIX and [=FreeBSD=] operating systems.
278
279!!!Open-source development delivers industry-leading features and performance
280The [=OpenSceneGraph=] 2.0 release is the culmination of 8 years of work by the lead developers and the open-source community that has grown up around the project. The real-time graphics industry and academia embraced it from the very beginning, deploying it in real-world applications, and actively participating in its development, testing and refinement. The end result is a high-quality library with a feature set relevant to application developers' needs.
281
282The theme for the 2.0 release has been making the [=OpenSceneGraph=] easier to use, yet more flexible and powerful.
283
284Features include:
285
286* New unified build system using [[http://www.cmake.org CMake]], which simplifies the build process, automatically detecting installed dependencies and providing build configuration as well as support for a wide range of development tools.
287* New libraries:
288** osgViewer - provides native windowing support and viewer functionality that scales from a single view embedded in a window to multi-thread, multi-gpu, multi-screen viewers and can handle multiple scene graphs at one time. 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.
289** osgManipulator - provides a set of interactive manipulators for scaling, rotating and moving objects in the scene.
290** osgShadow - provides an extensible framework for adding dynamic shadows to your scene.
291* New low-level extensible intersection framework that includes support for line, plane and polytope intersections.
292* New high-level intersection classes that support paged databases, [=LineOfSight=], [=HeightAboveTerrain=] and [=ElevationSlice=].
293* View-dependent overlay - provides ability to overlay text, country boundaries etc. directly on to terrain, even paged databases.
294* Plugins
295** Improvements to the [=OpenFlight=], COLLADA, [=AC3D=], DDS plugins and many more
296** New TXF texture font reader.
297** New [=VRML2=] reader (using the [=OpenVRML=] library).
298* Easier 3rd party windowing integration
299** With examples showing integration with GLUT, SDL, Qt, [=WxWidgets=] and MFC
300* External dependencies removed simplifying build and distribution
301** [=OpenThreads=] is moved into the core of [=OpenSceneGraph=] and is no longer an external dependency
302** Thanks to the integration of windowing support in osgViewer, [=Producer=] is no longer a dependency.

333!!![=OpenSceneGraph=] 1.2 release introduces Windows 64bit and AIX support, COLLADA support, processor affinity and texture atlas builder.
334
335PERTHSHIRE, 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.
336
337The [=OpenSceneGraph=]-1.2 release introduces:
338
339* 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.
340* Support for IBM's AIX operating system, bringing the total number of supported operating systems to 8.
341* 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=].
342* 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.
343* 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.
344* 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.
345* A range of bug fixes and API refinements.
346
347The [=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.

458BETA releases
459
46025th May 2005 - OpenSceneGraph-0.9.9
461
462>>> OpenGL Shading Language integrated into core, Introspection, movies, particle effects and much more... 
463
464Introduction to the OpenSceneGraph:
465
466The 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.
467   
468The OpenSceneGraph 0.9.9 release:
469   
470The 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.
471   
472The 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:
473       
474OpenGL Shader Language support:
475   
476OpenGL 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.
477       
478Introspection support:
479   
480The 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
481to 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.
482
483Better support for Apple native Windowing:
484
485Thanks 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.
486   
487Support for latest OpenGL extensions:
488   
489Support for the Non power of two texture feature of OpenGL 2.0 has been added
490to 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.
491   
492Terrain generation and rendering enhancements:
493   
494The 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.
495       
496Particle Effects:
497   
498To 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.
499   
500DXF and Movie plugins:
501   
502A 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.
503   
504Application and examples:
505   
506To 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.
507   
508There 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.
509   
510osgpbuffer also example now uses Producer's pbuffer support making it portable across platforms and much cleaner.
511   
512API refinements, bug fixes and performance improvements:
513   
514There 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.
515   
516We would like to thank the following engineers for their contributions in the 0.9.8 - 0.9.9.9 time frame (in alphabetic order):

626     
627    The TerraPage plugin has also been rewritten ontop of the OSG's
628    osg::PagedLOD and osgDB::DatabasePager which provides support for the
629    tile fallback mechanism to ensure that no holes or cracks appear in the
630    databases being roamed, and to achieve constant frame rate via load
631    balancing mechanisms with osgDB::DatabasePager.
632   
633    The osgDB::DatabasePager has been further improved to provide more
634    configurable load balancing which allows application developers to achieve
635    constant frame rates when using paged databases.
636   
637    Double Vec & Matrix classes & CoordinateSystemNode/EllipsoidModel class
638    have been introduced to better support browsing of large scale databases,
639    and to provide a mechanism for tracking the local up orientation when
640    roaming whole earth databases.
641   
642    osgUtil has been enhanced with:
643     - an improved triangle tipper class (osgUtil::TriStipVisitor),
644     - a new simplifier (osgUtil::Simplifer) for reducing triangle density of
645       osg::Geometry leaves (utilised by osgTerrain to provide simplification
646       of terrain tiles),
647     - improved and more configurable optimizer (osgUtil::Optimizer),
648     - a new utility class for compiling and releasing OpenGL objects
649      (osgUtil::GLObjectVisitor) replaces the previous and more limited
650       DisplayListVisitor.
651   
652    All the osgGA::MatrxManipulator's (used for camera manipulator etc) have
653    been revamped with usage of doubles internally, and with tracking of the
654    current CoordinateSystem if one is active, to be better support whole
655    earth databases.  All the MatrixManipulators have been extend to allow
656    the setting of a user defined home position.  Two new manipulators have
657    been introduced osgGA::TerrainManipulator, for roaming whole earth/terrain
658    databases, and osgGA::TrackerManipulator which allows the camera to be
659    attached to a node in the scene graph.
660
661    Movie support under Linux and OSX via libMpeg3 and Quicktime respectively,
662    which extend the new osg::ImageStream base class which allows application
663    developers access to playing, pausing and rewinding movies.
664
665    The conversion utility osgconv has been extended to allow compression of
666    textures and mipmap generation during conversion when writing to the native
667    .ive binary format.  Texture compression and pre computer mipmaps enable
668    faster loading of databases and lower utilisation of memory resources.
669
670    Write support added to JPG plugin.
671   
672    Write + 3D texture support added to DDS plugin.
673   
674    Pseudo loaders .trans, .rot and .scale have been added.
675   
676    Updated LWO, AC3D, BMP, IVE and FLT loaders.
677   
678    osg::TexGenNode has been added to provide a mechanism for positioning
679    OpenGL's texture coordinate generation planes.
680
681    Fourteen new examples have been added:
682   
683        osgdem            a utility for creating large scale geospatial paged
684                          database
685

703                          depends upon tracking the modelview matrix.
704
705        osgdistortion     an example of how to use prerendering of a texture to
706                          create a distortion effect.
707
708        osgsimple         a bare bones example of how to create a simple viewer
709                          using a Windowing toolkit, in this example using
710                          Producer, but is written so the example could easily
711                          be modified to work with other Windowing toolkit.
712
713        osgkeyboardmouse  adding to keyboard and mouse functionality on the
714                          osgsimple base.
715
716        osgsimplepager    adding database paging support to the osgsimple
717                          example.
718   
719        osgmovie          an example which creates a quad to render a loaded
720                          movie file with - requires the LibMpeg3 (Linux) or
721                          Quicktime (OSX) plugin to work.
722       
723        osgvolume         an example that reads a stack of 2d images to create
724                          a 3D texture, and creates a scene graph using
725                          standard OSG components (osg::ClipNode,
726                          osg::TexGenNode, osg::Billboard and
727                          osg::TexEnvCombine) to create a per per lit volume.
728
729   
730    Wrapping up the complete 0.9.7 release is a wide range of smaller features
731    enhancement and many bug fixes.
732
733
7342nd October 2003 - OpenSceneGraph-0.9.6-2
735
736    >>> osgFX Special Effects nodekit (for bumping mapping & cartoon effects etc), support for double Matrix traversals,
737    >>> improved build support, thread safety and robustness.
738   
739    The new osgFX nodekit, written by Marco Jez, adds a set of decorator
740    nodes that add can be conveniently added above subgraphs in your scene
741    to add special a range of special rendering effects.  Effects include
742    AnisotopicLight, BumpMapping, Scribe, Specular Highlights and Cartoon
743    rendering.
744   
745    Support for double Matrices has been added with the new Matrixd class,
746    and complimented by the a Matrixf class.  The original Matrix class is
747    now a typedef which can be set to either Matrixf or Matrixd (which is
748    now the default),  When the Matrix typedef is set to Matrixd and the OSG and
749    dependent apps are recompiled all internal operations such a cull traversals
750    will now be double with double matrices which much improved numerical
751    precision, making it ideal for datasets where a large values are contained
752    with transforms in the scene graph (such as with whole earth databases),
753    and when a transforms are nested which creates requires concatenation of
754    a number of matrices to get the final model view matrices. 
755   
756    The osgGA::MatrixManipulators (which are used to control the camera
757    position) and osgProducer/OpenProducer have been moved across to using
758    exclusively double Matrices.  This has been done to improve numerical
759    precision when computing camera positions, whilst having little impact
760    on performance since camera operations are only done a small number of
761    times per frame.
762   
763    osg::Quat now supports doubles by default, but also allows users to select
764    float version osg::Quat simply by changing the osg::Quat::value_type typedef.
765   
766    Work has been on OpenThreads and OpenProducer, in particular to improve
767    thread safety and robustness on the Win32 platform.  Reported crashes
768    on exit from osgProducer::Viewer based apps, and freezes during runtime
769    have been fixed.
770   
771    Threading problems which caused crashes in recent updates of the Terrapage
772    loader have also been fixed, and additional internal changes have been made
773    to improve the Terrapage loader's ability to hit constant frame rates.   
774    Support has also been added for loading light points directly from the
775    Terrapage database.
776
777    A new .iv/.wrl loader plugin, written by Vivek Rajan, at Magic Earth,
778    has been added to the distribution which uses with OpenInventor or Coin
779    to load model, converting them into OSG equivalents.  Coin has support
780    for VRML97 models, so can be used to import such models into the OSG. 
781    Since the new plugin is dependent on OpenInventor or Coin the compilation
782    is optional, but off by default. To compile this plugin under Unix, set
783    the environmental variable USE_INVENTOR or USE_COIN and recompile. 
784    Windows .dsp project file does to current exist, but should be
785    possible to add this.
786   
787    The .ive plugin has been improved with the addition of support for
788    osgSim light points, and various internal refinements to make it function
789    better on the various platforms supported by the OSG.  Note, these changes
790    mean that the .ive format has has changed and is no longer compatible
791    with previous version of .ive. It is recommend that one recreates .ive
792    for the original source via osgconv or similar to ensure consistency.
793
794    A JPEG2000 image plugin has added, written by Michael Gronager.  The new jp2
795    plugin uses the japser open source project to read and write JPEG2000 files.
796   
797    A scalar bar, and sphere segment helper classes have been added to osgSim,
798    the new osgscalarbar and osgspheresegment examples demonstrate how to use
799    these new features.
800   
801    To help handle running applications of graphics cards/drivers that exhibit
802    bugs with certain OpenGL extensions, support has been added to the GLextensions
803    code to allow extensions to be disabled via the new
804    osg::setGLExtensionDisableString(std::string) function or by setting an
805    OSG_GL_EXTENSION_DISABLE environmental variables.  Follows is an example of
806    the disable string:
807   
808        set OSG_GL_EXTENSION_DISABLE =
809             "ATI:GL_SGIS_generate_mipmap;Sun:GL_EXT_texture_filter_anisotropic:"
810
811    New examples include:
812   
813        osgforest - an example which demonstrates simple techniques for creating forests   
814        osgfxbrowser - an example which demonstrates the various osgFX Effects available   
815        osgscalabar - an example of how to set up the osgSim::ScalarBar.
816        osgspheresegment - an example of how to set up the osgSim::SphereSegement
817        osgpagelod - a very simply test program for setting up osg::PagedLOD/osgDB::DatabasePager
818   
81923rd July 2003 - OpenSceneGraph-0.9.5
820
821    >>> Support added for OpenGL2.0 shaders, native multi-threaded Database paging,
822    >>> high peformance binary format reading and writing,  .dds compressed image
823    >>> loader and ARB_fragment_program and ARB_vertex_buffer_object extensions,
824    >>> improvements to the Terrex .txp and OpenFlight .flt loaders.
825
826    The key new features of the 0.9.5 release are the new OpenGL2.0 nodekit, constant frame rate
827    database paging support,  classes,  and the new native .ive binary plugin which supports
828    both reading and writing of all core osg nodes, including inlining of compressed
829    and non-compressed imagery.
830   
831    The native database paging support, provided by the new osg::PageLOD and osgDB::DatabasePager,
832    achieves constant frame rate through threading of the database reading, and time based
833    incremental compile and delete of display lists, vertex_buffer_objects and texture objects.
834    A new TextureObjectManager class also caches a list of expired texture objects for reuse,
835    and allows new newly loading imagery to reuse expired texture objects, with the imagery
836    automatically subloaded to the reused texture objects.  This reuse happens transparently
837    and benefits other OSG usages such as the OSG's Terrapage loader.
838   
839    To provide support multi-thread operation of the OSG, such as multi-thread database paging
840    and multi-threaded, multi-window graphics enabled by OpenProducer, the OpenSceneGraph and
841    OpenProducer have now adopted the OpenThreads threading library, osgDB and osgProducer now
842    depend upon it.  OpenThreads is open source, light weight, cross platform C++ threading
843    which encapsulates the low level, platform specific threading API calls.  Currently pthreads
844    under Unix and Win32 threads under Windows are supported, with Sgi sproc threads to be
845    released very soon.  The OpenThreads project website can be found at http://openthreads.sf.net.   
846
847    The new .ive binary plugin was developed by Uni-C's VR-Center, and kindly submitted as
848    open source, adds support for binary reading and writing OSG nodes drawable and state
849    (including compressed/mipmapped) textures.  The .ive format produces a much faster
850    load times and smaller file size then native ASCII .osg format. Load times for .ive
851    files are also 10-20x faster then equivalent OpenFlight .flt and load in an already
852    optimized scene graph form making it much more suitable for paging.  Files can be
853    converted easily using the osgconv utility : osgconv myfile.flt myfile.ive
854   
855    The new osgGL2 nodekit library adds support for the OpenGL2.0 vertex ProgramObect and fragment
856    ShaderObject's recently ratified by the OpenGL ARB, . The osgGL2 uses the extension have local
857    prototypes which allow them to be compiled even in the absence of OpenGL headers that don't
858    support the GL2 extension, allowing to port to all platform, and at runtime the extensions are
859    queried for and used if available.  At time of release only 3DLabs WildcatVP series supported
860    this extension at runtime, but other graphics cards and manufactures will be releasing GL2
861    extension very soon and will be automatically supported by osgGL2. The osgGL2 was developed
862    by Mike Weiblen at 3DLabs whom have kindly submitted osgGL2 as open source and for inclusion
863    with the OSG distribution. 
864
865    The ARB_fragment_program, ARB_vertex_buffer_object and ARB_vertex_program attributes are
866    also now supported in core osg library.  The new osg::FragmentProgram state attribute
867    encapsulates the ARB_fragment_program which is supported by the recent graphics cards
868    from NVidia, ATI and 3DLabs.  Support for ARB_vertex_buffer_object and ARB_vertex_program
869    attributes have been added to the osg::Geometry class.  The ARB_vertex_buffer_object extension
870    can boost performance by as much as 50% when working on geometry bound data sets.
871
872    Two new image loaders, dds and pnm, and a 3dc point cloud have been added. The .dds plugin
873    adds support for compressed & mipped mapped imagery, making it ideal for applications where
874    large texture sizes or database paging is required. The pnm image loader reads the
875    pnm, pgm and pbm image formats. See http://netghost.narod.ru/gff/vendspec/pbm/ for details.
876
877    The Terrapage .txp plugin  been updated to include support for multi-texturing, layers and billboards
878    and includes improvements to multi-threaded pager, which has also been ported over to use OpenThreads.
879    The OpenFlight .flt plugin has also been improved and now support detail textures via multi-texturing.
880
881    TessellationHints now supported by ShapeDrawable which allow the shape primitives to be rendered
882    are vary levels of detail.
883
884    Supported has been added for auto scaling and rotating text into osgText.
885
886    Five new examples have been included in the distribution:
887   
888        osgtexturerectangle illustrates how to use the osg::TextureRectangle which encapsulates
889        the NV_texture_rectangle extension.
890       
891        osgprerendercubemap illustrates how to use pre rendering imagery to osg::TextureCubeMap
892        for tasks such as building a environmental texture maps.
893       
894        slideshow3D is a presentation tool which use a scene graph to store a render set of slides, each
895        slide containing layers which can contain bullet points, paragraph, imagery and 3d animated
896        models - and is effectively a 3D power point. The presentations can be built separately and stored in a .osg file or created by
897        slideshow3D via an xml file, two examples - introduction.xml and models.xml, which are included
898        in the OpenSceneGraph-Data-0.9.5 data distribution.  slideshow3D depends upon libxml2 for parsing
899        the xml files.
900       
901        osgpoints uses the osg::Point state attribute to attenuate and control point size and any points
902        loaded by the application.  This is a useful way of visualizing point data clouds.
903       
904        osgdemeter is example of how to integrate the Demeter, OSG using osgProducer::Viewer as a viewer
905        class.  This example depends upon the demeter terrain engine, which can be download from
906        http://www.terrainengine.com.
907
908    Camera style convenience set and get methods to osgUtil::SceneView, consolidating
909    previous functionality that was provided by both osg::SceneView and osg::Camara into one place.
910    This move has made osg::Camera redundant so has it been removed to avoid confusion,
911    usage inconsistencies and bloat of core libraries.
912   
913    The long time deprecated osg::GeoSet has been removed, to aid migration of old .osg datasets
914    osgconv has a copy of GeoSet and the .osg support for it so is able to convert any remaining
915    .osg database which contained GeoSet's.
916
917   
918
91928th April 2003  - OpenSceneGraph-0.9.4-2
920
921    >>> Multi-threaded, multi-pipe support via integration with OpenProducer,
922    >>> 64bit Linux support for Intel Intanium and AMD Opteron,
923    >>> new osgText library with greater performance, and thread safety,
924    >>> new DDS plug-in for compressed and non-compressed images,
925    >>> new MD2 plug-in adds support for animate Quake character and
926    >>> support added for NV_texture_rectangle.
927
928    The most significant new feature is the osgProducer library that adds
929    tight integration with OpenProducer, providing the OpenSceneGraph with a
930    scalable, configurable and portable framework for developing real-time
931    and interactive graphics applications.  The scalability afforded by
932    OpenProducer allows applications to be developed which run seamlessly
933    on single pipe machines up to multi-pipe machines such as Sgi Onyx
934    IR system, and Sun Zulu systems.
935    The osgProducer/OpenProducer framework automatically handles the
936    multi-threading of cull-draw pairs and GUI events.
937
938    All the example programs have been ported over from being based on
939    GLUT to using osgProducer (osgGLUT can now be found in the bazaar
940    section on the website). The move to osgProducer allows all the examples
941    to scale from running on laptops up to multiple CPU and graphics pipe systems.
942    The configuration of threading and multiple camera views can all be done
943    via ASCII configuration files, no need to recompile.  A number of
944    new examples have also been added or revamped, bringing the total to 42.
945
946    Also in the theme of increasing scalability there is support for 64bit Linux for both
947    IA64 (Intel Itanium) and x86-64 (AMD Opteron) which compliments the existing
948    support for Solaris and IRIX 64 bit compilation.  64 bit supports allows
949    the use of very large data sets, and potential performance improvements.
950
951    To help support development teams working with multiple build configuration,
952    the makefile system has been extended to allow multiple build targets to be
953    built from one source code base.  All makefiles are also now named GNUmakefile
954    which ensures that they are only run by gmake to avoid an confusion on system
955    where gmake isn't the default make tool.
956
957    A completely new osgText implemention has been developed which is simpler
958    to use, faster, and thread safe.  Support for high quality true type fonts
959    has now been moved to a freetype plug-in which is dynamically loaded on demand,
960    with the core osgText library providing a default font when the plug-in is
961    unavailable.  Moving the freetype dependency out of the osgText library makes
962    it just dependant on OpenGL and Standard C++ like the rest of the core libraries,
963    allowing osgText to compile by default on all platforms.
964
965    Improved thread safety has also been achieved in the core osg and osgUtil libraries
966    making work on multiple CPU/multi-pipe systems robust and with improved performance.
967
968    Two new plug-ins have been added, for loading DDS and MD2 data formats. The DDS plug-in
969    is for loading compressed and non-compressed images.  The MD2 plug-in loads Quake
970    animated characters.
971   
972    osg::TextureRectangle class has been added, which encapsulates the
973    NV_texture_rectangle and EXT_texture_rectangle extensions.  This is particularly
974    useful for render to texture algorithms, and dynamic paging of images such as for
975    rendering video streams.
976
977    Support for automatic subloading of osg::Texture2D textures has been added
978    so that when image data is updated the corresponding OpenGL texture is
979    automatically updated - no need for callbacks.  Also added to the osg::Texture
980    classes is the option of automatic unref'ing of texture image data once the data has
981    been download to all active OpenGL graphics contexts.
982   
983    A new osgUtil::DelaunayTriangulator utility class has been added.  This is ideal for
984    creating optimal triangular meshes from unconnected data points.
985
986    Two new classes, osg::ArgumentParser and osg::ApplicationUsage, have been introduced
987    to convineiently and robustly parse command line arguments and
988    report command line usage, environmental variables and keyboard and mouse bindings
989    used by applications.  Running any of the examples with -h or --help will report
990    full details example usage.  Keyboard and Mouse bindings usage is now also available as
991    a HUD on all examples, simply press 'h' while the app is running to
992    bring up help.
993
994    A database cache in the osgDB library has been added, along with a clean up
995    of memory management in the OpenFlight loader, make development of
996    dynamic paging of databases easier and more robust.
997   
998    Support for early abort of rendering has been added, which is useful for
999    interactive applications which occasionally have rendering that takes that long
1000    enough (i.e.several seconds) that end users may wish to abort during the drawing.
1001
1002    There have also been many general API improvements and bug fixes, too many to enumerate,
1003    but all go to solidify the quality of the scene graph and its accompanying libraries. 
1004   
1005    The combination of new features, robustness and scalability mark this release as a
1006    significant step towards 1.0.

101024th January 2003 - OpenSceneGraph-0.9.3.tar.gz
1011
1012    >>> adds support navigational light points, multi-threaded dynamic
1013    >>> paging of Terrapage databases, ARB_vertex_program extension,
1014    >>> DirectD .x model loader, and integration with OpenProducer for
1015    >>> multi-threaded, multi-window/pipe rendering.
1016
1017    Added osgProducer library which integrates the OpenSceneGraph seemlessly
1018    with OpenProducer to provide runtime configurable management of windows
1019    and multipipe graphic systems.  The osgproducer demo illustrate how
1020    developers can write applications very simply that harness the power
1021    of the OpenProducer and OpenSceneGraph in an extremely flexible way.
1022    OpenProducer can be downloaded from:
1023    http://www.andesengineering.com/BlueMarbleViewer/producer_install.html
1024
1025    Support added for dynamic paging of Terrage databases, the required
1026    multi-threading is set up by defult.  All the end user application need
1027    to do is load the database and the paging then happens automatically -
1028    without any need for intervention by the users application.
1029
1030    Addition of osgSim which is NodeKit designed for visual simulation
1031    market, currently features high fidelity light points support.  Light
1032    point sectors, blink sequences and groups, and light point fading are
1033    all supported.
1034
1035    From Brede Johansen, support added for the ARB VertexProgram extension
1036    with osgvertexprogram demo showing reflection and refraction in action, and
1037    osgpbuffer demo for Win32.
1038   
1039    From Ulrich Hertlein, new DirectX .x model loader.
1040
1041    From Tree, Support for encoded text types in osgText.

1045
1046    New osglogo demo - features anti-aliased TrueType text and animation.
1047   
1048    The app phase of operations on the scene graph has been renamed
1049    the update phase to make its function clearer. The main phases are now
1050    named now does update, cull, draw.  The AppVisitor, set/getAppCallback etc
1051    have be renamed UpdateVisitor, set/getUpdateCallback etc.
1052
1053    Removed the osg/ManagerManger and associated #define osgNew's, this has
1054    been done to simplify users code and to solve the lack of thread safety
1055    that was causing problems with the MemoryManager.
1056   
1057    Support added for reading and writing of callbacks in the .osg format.
1058   
1059    Support added for reading and writing of osg::Shapes in the .osg format.

1071    >>> New AC3D and GEO loaders, new Shape primitives, improved OpenFlight support.
1072
1073    From Geoff Michel, AC3D .wc and Carbon Graphics GEO .geo loaders.
1074
1075    Support for multi-texturing added to OpenFlight loader.
1076   
1077    LOD has been revamped to allow independent min and max ranges for
1078    each LOD child, bringing it inline with the OpenFlight style LOD
1079    representation.
1080
1081    Switch has been revamped to allow independent switching on or off of
1082    each Switch child, bringing it inline with the OpenFlight style Switch
1083    representation.
1084
1085    New osg::Shape geometry primitives added which allow the specification
1086    of geometry in a form that can accelerate collision detection, and as
1087    a way of specifying the geometry to tessellate.  Shapes include
1088    Sphere, Oriented Box, Cone, Cylinder, Grid, TriangleMesh, ConvexHull
1089    and CompositeShape which allows the storage of a hierarchy of shapes.
1090   
1091    Geometry has been extended to all per primitive bindings and
1092    per primitive set bindings of attributes, and indexing of attributes
1093    with the same or different index lists for each attribute list.
1094
1095    From Macro Jez, new cubemap helper classes.
1096
1097    Support added for handling different extensions on different graphics
1098    contexts.

1117
1118    >>> 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!
1119
1120    Despite only 6 weeks passing between 0.9.0 and this latest 0.9.1 release
1121    there has been a number of significant new features, API clean ups and
1122    bug fixes.  Follows is a quick run through the key improvements.
1123
1124    Addition of osg::Texture1D, Texture2D & Texture3D classes, Texture2D replaces
1125    the original osg::Texture, which has now become a pure virtual base class. All
1126    Texture classes, including TextureCubeMap are derived from this base class..
1127   
1128    New osgtexture1D and osgtexture3D demos demonstrate the new texture classes in
1129    action.
1130   
1131    The build system has been updated to support HP-UX.  This adds one of the last
1132    remaining mainstream platforms supported.
1133
1134    A new Inventor/VRML1.0 loader was added.  The inventor format has been requested
1135    on numerous occasions, so this is a welcome addition.
1136   
1137    Support added to lwo plugin for loading the new lwo2 format.
1138
1139    osg::TexEnvCombine implemented texture_env_combine and texture_env_crossbar
1140    and texture_env_dot3 extensions.
1141
1142    osg::TexEnv texture_env_add added.
1143
1144    A osg::Sequence node has finally been implemented.  It is accompanied by a
1145    demo, osgsequence.
1146
1147    osg::DOFTransformNode implemented.
1148
1149    Support for OpenFlight15.7 added, DOFTransforms and general enhancements and
1150    bug fixes.
1151
1152    New PROTECTED mode for protecting local state mode and attributes from be
1153    overridden from state above it in the scene graph.
1154   
1155    Support for fog coord and secondary colors extensions added to osg::Geometry.
1156
1157    osg::Billboard has been improved to allow rotations around all axes, as well
1158    as point rotations.  Check osgbillboard for a new improved demo.
1159
1160    The osglight example has been improved by utilizing AnimationPath and
1161    PositionAttitudeTransform to keep light sources in motion.
1162
1163    osg::AnimationPath improved, now allowing swing and looping behavior and
1164    with two new app callbacks which can update PositionAttitudeTransform
1165    and MatrixTransform respectively.
1166   
1167    Support for writing osg::Image's to .rgb format added.
1168
1169    To keep the overall API clean, and the following items have been
1170    renamed and deprecated parts of the API have been removed:
1171
1172    Renamed classes:
1173
1174            EarthSky        -> ClearNode
1175            Transparency    -> BlendFunc
1176            Texture         -> Texture2D  (old style subload parameters removed)
1177
1178    Method's changed
1179
1180            Matrix          -> makeRotate(..) euler angles parameters generalized.
1181            Quat            -> makeRotate(..) euler angles parameters generalized.
1182
1183            BoundingBox     -> isValid() renamed valid()
1184            BoundingSphere  -> isValid() renamed valid()
1185
1186            StateAttribute  -> OVERRIDE_OFF & OVERRIDE_ON which were short hand
1187                               versions of OVERRIDE | OFF and OVERRIDE | ON
1188                               removed, as the meaning of the bitmask was
1189                               often confused by the short hand notation.
1190
1191
1192            Transform       -> setMatrix/getMatrix() etc methods removed,
1193                               Transform becoming the transform base class,
1194                               with MatrixTransform taking over all the original
1195                               functionality.
1196
1197
119819th July 2002 - OpenSceneGraph-0.9.0.tar.gz
1199
1200    >>> OpenSceneGraph goes beta - Multitexturing, Occlusion Culling, Particles and much more added!
1201
1202    This release marks the beginning of the beta phase of the OpenSceneGraph
1203    development, which means that all the major core features are now
1204    in the scene graph, and 1.0 is not far away.  Its performance, features
1205    and portability already compares very favorably to other scene graphs,
1206    both comerical and open source. 
1207
1208    Multi-texturing support added to osg::StateSet, osg::Geometry, osg::State
1209    and txp loader, so multi-texturing can now be done with very little coding
1210    from the user - all you need to do is specify the texture unit to use
1211    when setting texturing state and texture coordinates and the rest is
1212    handled automatically by the scene graph!
1213   
1214    The new osg::Geometry classes which supersedes the old Performer style
1215    osg::GeoSet, support multi-texturing, and uses sharable osg::Arrays which
1216    utilize std::vector<> for data storage and manipulation.
1217
1218    Shadow volume occlusion culling adding to the core OSG, developed as a
1219    collobaration between Mike Connell and Robert Osfield. Our implementation
1220    uses convex planer occluders, with support for holes to allow larger
1221    and more effective occluders to be used. The approach is software
1222    based so it 100% portable, and by culling during the cull traversal
1223    both CPU and GPU loads are significantly reduced, making it an extremely
1224    powerful feature for large scale urban and indoor visulisation.
1225
1226    osgParticle developed by Marco Jez adds support for a range of particle
1227    effects such smoke, fires, engine plumes, fountains, fire works, and
1228    is fully customizable to produce your own favorite effects. osgParticle
1229    is a NodeKit (see below) which can be directly linked to in your
1230    application to allow you to create particle effects by hand, or have
1231    the library dynamically loaded in when you load a database which contains
1232    particle effects.
1233   
1234    osgGA (Gui Abstraction) library written by Neil Salter adds classes for
1235    adapting different GUI toolkits to work with a standard set of manipulators for
1236    modifying the scene, such as camera and state manipulators.
1237   
1238    Support has been added to the plugin architecture to facilitate the
1239    development of NodeKits - add on libraries which can used directly
1240    in your code, or loaded indirectly when loading from file.  The
1241    later allows you to load a .osg file with text or particle effects
1242    in them,the plugin architecture automatically loads the required
1243    library which supports these features.
1244
1245    A range of new demos have been as code examples, and to demonstrate
1246    the range of features that OpenSceneGraph delivers:
1247
1248        osgoccluder  - demonstrates ocllusion culling, and has a mode
1249                       which allows the users to interactively create
1250                       their own convex planer occluders.
1251        osghud       - how to mix head up display with 3d views.
1252        osgparticle  - shows the new osgParticle node kit in action.               
1253        osgprerender - pre renders and scene then textures the result onto
1254                       an animated flag.
1255        osgcallback  - examples of the full range of callbacks that you
1256                       can use to add dynamic behaviors to your scene graph.
1257        osglight     - a simple example of how to set up spot and position
1258                       lights in the scene.
1259        osgclip      - illustrates how to add clip planes to you scene.
1260        osggeometry  - examples of the different ways to set up primitives
1261                       and vertex/color/normal and texture attributes in
1262                       the new osg::Geometry class.
1263        osgmultitexture - a simple example which adds a spherical reflection
1264                        map to a whole scene using the second texture unit
1265                        if one exists.
1266       
1267    osg::Drawable::PrimtiveFunctor has also been added to allow querrying
1268    of primitive data with Drawables subclasses without requiring knowledge
1269    of the types of Drawable subclasses that exists.  This decoupling makes
1270    it a very powerful and flexible utility.
1271

127326th April 2002 - OpenSceneGraph-0.8.45.tar.gz
1274
1275    >>> Support added for Solaris, texture cube mapping & muliple projections.
1276   
1277    The OpenSceneGraph now has a new Makefile system which supports all Unix
1278    compilation including the new addition to the family - Solaris! 
1279
1280    OpenSceneGraph welcomes Solaris to the list of supported platforms.  This
1281    release puts all of the OpenSceneGraph functionality at the fingertips of
1282    Sun Microsystem's customers and developers.  Solaris users can now have
1283    the benefit of a high performance scene graph for visual simulation,
1284    virtual reality, scientific visualization, CAD, and architectural
1285    walk-throughs.  Many thanks to Sun for providing resources for the port.
1286   
1287    Additional html documentation has been added to the distribution to
1288    make it easier to get an understanding of scene graph technology and
1289    the project itself and how to make use of it. 
1290
1291    Support has also been added for OpenGL's texture cube mapping which
1292    is ideal for accurate environmental reflections and much more.
1293   
1294    The scene graph has been extended to allow multiple projection (via
1295    the new osg::Projection node) and viewports within one scene graphs,
1296    this makes it much easier to set up head up displays, and we have
1297    an example to demonstrate how easy it is - osghud.
1298   
1299    The osgUtil::CullVisitor and osgUtil::SceneView has been revamped
1300    removing the dependency on osg::Camera, which is now simply an
1301    option for SceneView rather than a requirement.  This allows users
1302    to set the camera entirely with the scene graph or create their own
1303    camera classes and use them with SceneView.  The existing osg::Camera
1304    has also been simplified as support for setting projection and
1305    modelview matrices have been moved out to the cull traversal.
1306   
1307    Several sets of node callbacks have been added, including a Cull
1308    NodeCallback on each Node, ComputeTransformCallback on Transform
1309    Nodes, EvaluateLODCallback on LOD nodes, ComputeBillboardCallback
1310    on Billboard nodes.  These make it my easier to customize the
1311    scene graphs behavior at runtime.
1312   
1313    osg::Image::readPixels() and support for writing .bmp files has been
1314    added which has made it easy to add screen capture the any OpenSceneGraph
1315    application.  This feature is demonstrated in the scene graph viewer
1316    which comes with the distribution - just press 'O' to output a screenshot.
1317   
1318    Finally, include/osg/MemoryManager has been added which overrides new
1319    and delete for debug builds. The override new and delete track allocations
1320    and deallocations, ensure they are matched, checked for memory under and
1321    overruns, and outputs a memleaks.log file on the results of executing
1322    your applications.  This help track down a number of memory leaks and
1323    unmatched new and deletes within the OpenSceneGraph and should make
1324    it easier to do with users applications as well.
1325   
1326    All in all, the OpenSceneGraph is now more portable, easier to
1327    customize, cleaner and more robust.  Beta release and 1.0 is now not
1328    far away!
1329   
1330
133124th February 2002 - osg-0.8.44.tar.gzosg-
1332
1333    >>> Support added for Mac OSX, Cygwin and MinGW, and new TerraPage loader.
1334   
1335    The major item for this release is the completion of the Mac OSX port,
1336    thanks to Phil Atkin and others for making this happen.
1337   
1338    Also added to support for Cygwin and MinGW builds which gives Windows
1339    users a free and robust alternative to the Visual C++, which we
1340    have Norman Vine to thank.
1341   
1342    Funtionality wise there has been a great deal of work behind the scenes
1343    putting in place a flexible and extensible framework for handling
1344    transform nodes, users can now extend the osg::Transform node through
1345    subclassing or via callbacks.  This work will underpin future work
1346    on moving camera setup into the scene graph, and environmental effects
1347    such as cloud layers, ground planes, stars and earth sky implementations
1348    which are planned for the next release.
1349   
1350    Callbacks and virtual methods have also been added to the osg::LOD &
1351    osg::Billboard to allow users to customize their behavior.  Draw
1352    callbacks have also been added to allow customization of osg::Drawables
1353    at runtime.
1354   
1355    The Open Flight .flt loader has undergone a number of improvements
1356    including support for instancing and billboards.
1357   
1358    New TerraPage (.txp) loader and OpenDX writer (.dx) plugins have been added.
1359   
1360    Support for the clone operation on osg::Object's has been expanded
1361    to allow cloneType() - a simple clone an blank object of the same type,
1362    and clone(CopyOp&) where CopyOp is a functor which allows users to
1363    specify the deep copy vs shallow copying of object data.
1364   
1365
13662nd January 2002 - osg-0.8.43.tar.gz
1367
1368    >>> Support for TrueType text, Stereo out of the box, and much more.
1369   
1370    Since the last release the OSG has moved to CVS based developments so
1371    many users will have seen gradual increments in functionality and changes
1372    to the API. Whereas a the leap from 0.8.42 to 0.8.43 is actually quite
1373    significant is likely to require code changes as several significant parts
1374    of the API have evolved to a more mature state.
1375   
1376    The most significant new functionality is the addition of the osgText
1377    library which provides support for true type font rendering, as textured,
1378    polygonal, pixmap, bitmap and 3D fonts.
1379   
1380    We now have new osg::Matrix implementation which cleans up its interface.
1381    Also all angular parameters are now based on radians rather than degrees
1382    as before (and as in Performer), this has been done to be more consistent
1383    with the basic trignometric functions and standard maths conventions.
1384   
1385    Scene graph optimization has been added which can boost performance
1386    on some database by as much as an order of magnititude, this is
1387    particularily noticable in .flt based databases.  Display list performance
1388    has also been boosted on NVidia based machines thanks to changing the
1389    compilation and execution of display list into two seperate operations.
1390   
1391    App callbacks are now supported on all Nodes, and there now a proper
1392    app traversal which can be used to animate the scene.
1393   
1394    Stereo support has been added into the osgUtil::SceneView which allows
1395    quad buffered/anaglyphic stereo to enabled easily for almost all OSG
1396    applications without code modifications - simple set environmental
1397    variable or pass in appropriate arguments and your app will render in
1398    stereo!
1399
1400    src/Demos/osgcluster has been added to demonstrate how easy it is
1401    to set up a graphics cluster across a standard networked PC's.
1402
1403    There have been many minor code changes to fix bugs and address
1404    performance bottlenecks or to improve extensibility was, representing
1405    a significant step towards API maturity and a beta release which is
1406    now not far away.
1407
1408
14099th August 2001 - osg-0.8.42.tar.gz
1410
1411    >>> New osgWX library for integration of OSG with wxWindows apps.
1412
1413    This release sees a relatively minor number of enhancements over
1414    0.8.41, the most significant being the new osgWX library and wxsgv
1415    demo written by Ben Discoe.
1416   
1417    Also from Brede Johansen in this release is the improvements in support for older
1418    .flt (Open Flight) files such versions 12 & 13.  Previously only version
1419    15.6 files had been tested and developed to.
1420   
1421    Last but by no means least, several bug fixes related to view frustum
1422    culling have been made.
1423
1424
142525th July 2001 - osg-0.8.41.tar.gz
1426
1427    >>> Support added for multi-pass and multi-stage rendering including Impostors.
1428
1429    The key feature developed is a highly flexible framework for multi-pass and
1430    multi-stage rendering techniques.  Unlike most scene graphs and games
1431    engines the OSG has as dynamic framework which automatically configures
1432    itself at runtime.
1433
1434    Building ontop of the new framework's multi-stage rendering capabilities,
1435    support for Impostors (hirachical image caching) has been integrated into
1436    the core scene graph  library making extremely easy to take advantage of
1437    this advanced rendering techinque - normally only seen in research papers.
1438    Check out osgimpostor demo to see how easy it is to add osg::Impostor
1439    nodes to your own models. Impostors are particularily effective are
1440    reducing scene complexity whilest minimizing the visual impact, making it
1441    ideal for scenes with large numbers of complex objects such as a city
1442    scene, or a dense forest.
1443   
1444    Taking advantage of the new framework's multi-pass rendering capabilities
1445    is osgreflect demo which illustrates how to achieve planar relfections
1446    using the stencil buffer and multi-pass rendering.
1447   
1448    The cool thing about both the osgreflect and osgimpostor demos is that
1449    there is no hardwiring to achieve the results, the scene graph stores
1450    all the information neccessary to specify the number and type of rendering
1451    passes, and the framework handles the rest behind the scenes.  This also
1452    makes it very easy to add these advanced rendering techinques to your
1453    own applications as everything is cleanly encapsulated with
1454    osgUtil::SceneView.
1455
1456    New loaders have been added to support .lwo (Light Wave), .obj
1457    (Alias Wavefront) and .dw (Design Workshop) 3D file formats making it
1458    even easier to compose your own worlds from models sourced from the
1459    web or your own.
1460   
1461    osg::Camera has been totally revamped and now supports asymetric
1462    and othographics projections in addition to the symetrical perspective
1463    projections.
1464
1465    And finally, support for texture subloading has been added to osg::Texture
1466    and osg::Image.  This allows textures to be updated dynamically, and
1467    has already been used for mpeg video playback!   
1468
1469

1471
1472    >>> Project lead, Robert Osfield, makes full-time commitment to OSG.
1473
1474    This is the first full release since project lead, Robert Osfield, made
1475    a move to pursue the OSG's development full-time.  This commitment has
1476    been made to bring the API rapidly towards maturity, and to provide
1477    high quality support and consultancy services.  Please contact
1478    robert@openscenegraph.com if you have any queries.
1479
1480    This release marks a significant step forward in the maturity of the
1481    API, with several major changes to the library in the areas of state
1482    handling, database support, and portability.
1483
1484    To improve the extensibility of the OSG's handling of OpenGL state,
1485    new classes have been introduced to replace the previous hardwired
1486    state handling classes.  The new classes also allow improved state
1487    sorting and lazy state updating which boosts both cull traversal
1488    and particularly draw traversal performance.
1489
1490    To improve the modularity, interopability and conceptual clarity the
1491    support classes for database loading have been moved from the core
1492    osg library into their own osgDB library.  Support for the .osg
1493    ASCII native database format and the .rgb reader has moved into its own
1494    osgPlugins library to further the cleanliness of the core library.
1495
1496    Support has be added for multiple OpenGL context's and hence multi-pipe
1497    systems such as sgi's Onyx2, allowing each context to have its own
1498    display list and texture objects.
1499
1500    The culler and rendering support in osgUtil has also been improved, and
1501    significantly speeded up for complex models.
1502
1503    Also just in, thanks to Randall Hopper for adding support for FreeBSD :-)

1507
1508    >>> Port of OSG to MacOS underway
1509
1510    The first steps towards support of MacOS have been taken by Bryan Woods,
1511    adding Metrowerks project files and adding support for MacOS into the
1512    core scene graph.  Work still in progress so assistance welcome to
1513    complete the task.
1514
1515    Other major developments have been the addition of two new base classes
1516    osg::StateAttribute and osg::Drawable which are designed to allow greater
1517    extensibility of OpenGL state management and primitives.

1521
1522    >>> New 3DS loader added
1523
1524    The OpenSceneGraph now supports the 3DS file format. This makes
1525    available a huge range of potential models. Check out
1526    http://www.3dcafe.com or http://www.3drocketfuel.com for some juice.
1527
152810th Feburary 2001 - osg_src-0.8-37.tar.gz
1529
1530    >>> Texture compression now supported
1531
1532    The OpenSceneGraph now provides support for ARB and S3TC texture
1533    compression. This allows more textures to be loaded onto graphics
1534    card memory, resulting in happier users and a better world in which
1535    to live.
1536
1537    This release also sees the addition of a simple hang gliding flight sim
1538    demo.
1539
154025th January 2001 - osg_src-0.8-35.tar.gz
1541
1542    >>> Anisotropic texturing now supported <i>and</i> loading of gzip compressed files
1543
1544    Anisotropic texturing provides for the next step in quality texturing
1545    filtering above tri-linear and is especially effective when viewing
1546    texture surfaces at shallow angles.
1547
1548    Also added in this release is on-the-fly support for loading gzipped
1549    (.osgtgz, .tgz) and zipped (.zip) database files.  This features allows
1550    users to store whole databases (models and textures) in a single
1551    tar ball and unpack them automatically on running the osg.  This
1552    is ideal for browsing the web.
1553
155422nd December 2000 - osg_src-0.8-33.tar.gz
1555
1556    >>> Support added for OpenGL vertex arrays, and several key image loaders.
1557   
1558    Support for OpenGL vertex arrays has been added to improve performance,
1559    particularly accelerating PC based graphics.
1560
1561    Also added is support gif, jpeg, pic, tga, tiff image formats via
1562    dynamic plugins.
1563
15648th Decemeber 2000 - osg_src-0.8-32.tar.gz
1565
1566    >>> New high resolution, low latency timer class - osg::Timer.
1567
1568    Real-time graphics relies upon accurate timers for updating physics
1569    simulations and managing constant framerates.  The OSG now provides
1570    osg::Timer which, when supported, takes advantage of hardware timers.
1571
1572
157318th November 2000 - osg_src-0.8-29.tar.gz
1574
1575    >>> Support for detail drawing with osg::PolygonOffset.
1576
1577    Rendering of polygons which overlay underlying geometry, such
1578    as white lines on a runway, can now be achieved utilizing the
1579    new osg::PolygonOffset which encapsulates glPolygonOffset to
1580    avoid z fighting which otherwise hampers such detailing.
1581
158210th November 2000 - osg_src-0.8-28.tar.gz
1583
1584    >>> New Open Flight .flt loader!
1585
1586    Thanks to Brede Johansen submission of .flt loader, the OSG can now
1587    read Open Flight .flt databases.
1588
15893rd November 2000 - osg_src-0.8-26.tar.gz
1590
1591    >>> Driving and Flight modes have been added to viewers.
1592
1593    osgUtil::DriveManipulator and osgUtil::FlightManipulator have been
1594    added to allow the scene graph viewer (sgv) and other viewers to
1595    support a drive and flying modes.  These modes can be accessed
1596    in sgv by pressing '2' and '3' respectively ('1' returns to
1597    trackball manipulator).  Left mouse button accelerates forward,
1598    middle stops motion and right deccelerates.
