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

308!!![=OpenSceneGraph=] 1.2 release introduces Windows 64bit and AIX support, COLLADA support, processor affinity and texture atlas builder.
309
310PERTHSHIRE, 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.
311
312The [=OpenSceneGraph=]-1.2 release introduces:
313
314* 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.
315* Support for IBM's AIX operating system, bringing the total number of supported operating systems to 8.
316* 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=].
317* 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.
318* 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.
319* 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.
320* A range of bug fixes and API refinements.
321
322The [=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.

433BETA releases
434
43525th May 2005 - OpenSceneGraph-0.9.9
436
437>>> OpenGL Shading Language integrated into core, Introspection, movies, particle effects and much more... 
438
439Introduction to the OpenSceneGraph:
440
441The 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.
442   
443The OpenSceneGraph 0.9.9 release:
444   
445The 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.
446   
447The 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:
448       
449OpenGL Shader Language support:
450   
451OpenGL 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.
452       
453Introspection support:
454   
455The 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
456to 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.
457
458Better support for Apple native Windowing:
459
460Thanks 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.
461   
462Support for latest OpenGL extensions:
463   
464Support for the Non power of two texture feature of OpenGL 2.0 has been added
465to 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.
466   
467Terrain generation and rendering enhancements:
468   
469The 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.
470       
471Particle Effects:
472   
473To 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.
474   
475DXF and Movie plugins:
476   
477A 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.
478   
479Application and examples:
480   
481To 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.
482   
483There 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.
484   
485osgpbuffer also example now uses Producer's pbuffer support making it portable across platforms and much cleaner.
486   
487API refinements, bug fixes and performance improvements:
488   
489There 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.
490   
491We would like to thank the following engineers for their contributions in the 0.9.8 - 0.9.9.9 time frame (in alphabetic order):

585   
586
5879th August 2004 - OpenSceneGraph-0.9.7
588
589    >>> support for and generation of large scale geospatial databases,
590    >>> support for movies and examples of shadows and volume rendering.
591   
592    The 0.9.7 encompasses many improvements, bug fixes, new examples and
593    significant new functionality, the most notable of which is a new
594    osgTerrain library for generation of large scale geospatial databases.
595   
596    The new osgTerrain library and associated osgdem utility program
597    allows users to use moziacs of geospatial imagery and digital elevation
598    maps to generate a complete paged database which can be used with
599    standard OSG viewers, and users programs. By utilising GDAL to load the
600    imagery and DEM's a wide range of geospatial formats are supported.   
601     
602    The TerraPage plugin has also been rewritten ontop of the OSG's
603    osg::PagedLOD and osgDB::DatabasePager which provides support for the
604    tile fallback mechanism to ensure that no holes or cracks appear in the
605    databases being roamed, and to achieve constant frame rate via load
606    balancing mechanisms with osgDB::DatabasePager.
607   
608    The osgDB::DatabasePager has been further improved to provide more
609    configurable load balancing which allows application developers to achieve
610    constant frame rates when using paged databases.
611   
612    Double Vec & Matrix classes & CoordinateSystemNode/EllipsoidModel class
613    have been introduced to better support browsing of large scale databases,
614    and to provide a mechanism for tracking the local up orientation when
615    roaming whole earth databases.
616   
617    osgUtil has been enhanced with:
618     - an improved triangle tipper class (osgUtil::TriStipVisitor),
619     - a new simplifier (osgUtil::Simplifer) for reducing triangle density of
620       osg::Geometry leaves (utilised by osgTerrain to provide simplification
621       of terrain tiles),
622     - improved and more configurable optimizer (osgUtil::Optimizer),
623     - a new utility class for compiling and releasing OpenGL objects
624      (osgUtil::GLObjectVisitor) replaces the previous and more limited
625       DisplayListVisitor.
626   
627    All the osgGA::MatrxManipulator's (used for camera manipulator etc) have
628    been revamped with usage of doubles internally, and with tracking of the
629    current CoordinateSystem if one is active, to be better support whole
630    earth databases.  All the MatrixManipulators have been extend to allow
631    the setting of a user defined home position.  Two new manipulators have
632    been introduced osgGA::TerrainManipulator, for roaming whole earth/terrain
633    databases, and osgGA::TrackerManipulator which allows the camera to be
634    attached to a node in the scene graph.
635
636    Movie support under Linux and OSX via libMpeg3 and Quicktime respectively,
637    which extend the new osg::ImageStream base class which allows application
638    developers access to playing, pausing and rewinding movies.
639
640    The conversion utility osgconv has been extended to allow compression of
641    textures and mipmap generation during conversion when writing to the native
642    .ive binary format.  Texture compression and pre computer mipmaps enable
643    faster loading of databases and lower utilisation of memory resources.
644
645    Write support added to JPG plugin.
646   
647    Write + 3D texture support added to DDS plugin.
648

652   
653    osg::TexGenNode has been added to provide a mechanism for positioning
654    OpenGL's texture coordinate generation planes.
655
656    Fourteen new examples have been added:

682
683        osgsimple         a bare bones example of how to create a simple viewer
684                          using a Windowing toolkit, in this example using
685                          Producer, but is written so the example could easily
686                          be modified to work with other Windowing toolkit.
687
688        osgkeyboardmouse  adding to keyboard and mouse functionality on the
689                          osgsimple base.
690
691        osgsimplepager    adding database paging support to the osgsimple
692                          example.
693   
694        osgmovie          an example which creates a quad to render a loaded
695                          movie file with - requires the LibMpeg3 (Linux) or
696                          Quicktime (OSX) plugin to work.
697       
698        osgvolume         an example that reads a stack of 2d images to create
699                          a 3D texture, and creates a scene graph using
700                          standard OSG components (osg::ClipNode,
701                          osg::TexGenNode, osg::Billboard and
702                          osg::TexEnvCombine) to create a per per lit volume.
703
704   
705    Wrapping up the complete 0.9.7 release is a wide range of smaller features
706    enhancement and many bug fixes.
707
708
7092nd October 2003 - OpenSceneGraph-0.9.6-2
710
711    >>> osgFX Special Effects nodekit (for bumping mapping & cartoon effects etc), support for double Matrix traversals,
712    >>> improved build support, thread safety and robustness.
713   
714    The new osgFX nodekit, written by Marco Jez, adds a set of decorator
715    nodes that add can be conveniently added above subgraphs in your scene
716    to add special a range of special rendering effects.  Effects include
717    AnisotopicLight, BumpMapping, Scribe, Specular Highlights and Cartoon
718    rendering.
719   
720    Support for double Matrices has been added with the new Matrixd class,
721    and complimented by the a Matrixf class.  The original Matrix class is
722    now a typedef which can be set to either Matrixf or Matrixd (which is
723    now the default),  When the Matrix typedef is set to Matrixd and the OSG and
724    dependent apps are recompiled all internal operations such a cull traversals
725    will now be double with double matrices which much improved numerical
726    precision, making it ideal for datasets where a large values are contained
727    with transforms in the scene graph (such as with whole earth databases),
728    and when a transforms are nested which creates requires concatenation of
729    a number of matrices to get the final model view matrices. 
730   
731    The osgGA::MatrixManipulators (which are used to control the camera
732    position) and osgProducer/OpenProducer have been moved across to using
733    exclusively double Matrices.  This has been done to improve numerical
734    precision when computing camera positions, whilst having little impact
735    on performance since camera operations are only done a small number of
736    times per frame.
737   
738    osg::Quat now supports doubles by default, but also allows users to select
739    float version osg::Quat simply by changing the osg::Quat::value_type typedef.
740   
741    Work has been on OpenThreads and OpenProducer, in particular to improve
742    thread safety and robustness on the Win32 platform.  Reported crashes
743    on exit from osgProducer::Viewer based apps, and freezes during runtime
744    have been fixed.
745   
746    Threading problems which caused crashes in recent updates of the Terrapage
747    loader have also been fixed, and additional internal changes have been made
748    to improve the Terrapage loader's ability to hit constant frame rates.   
749    Support has also been added for loading light points directly from the
750    Terrapage database.
751
752    A new .iv/.wrl loader plugin, written by Vivek Rajan, at Magic Earth,
753    has been added to the distribution which uses with OpenInventor or Coin
754    to load model, converting them into OSG equivalents.  Coin has support
755    for VRML97 models, so can be used to import such models into the OSG. 
756    Since the new plugin is dependent on OpenInventor or Coin the compilation
757    is optional, but off by default. To compile this plugin under Unix, set
758    the environmental variable USE_INVENTOR or USE_COIN and recompile. 
759    Windows .dsp project file does to current exist, but should be
760    possible to add this.
761   
762    The .ive plugin has been improved with the addition of support for
763    osgSim light points, and various internal refinements to make it function
764    better on the various platforms supported by the OSG.  Note, these changes
765    mean that the .ive format has has changed and is no longer compatible
766    with previous version of .ive. It is recommend that one recreates .ive
767    for the original source via osgconv or similar to ensure consistency.
768
769    A JPEG2000 image plugin has added, written by Michael Gronager.  The new jp2
770    plugin uses the japser open source project to read and write JPEG2000 files.
771   
772    A scalar bar, and sphere segment helper classes have been added to osgSim,
773    the new osgscalarbar and osgspheresegment examples demonstrate how to use
774    these new features.
775   
776    To help handle running applications of graphics cards/drivers that exhibit
777    bugs with certain OpenGL extensions, support has been added to the GLextensions
778    code to allow extensions to be disabled via the new
779    osg::setGLExtensionDisableString(std::string) function or by setting an
780    OSG_GL_EXTENSION_DISABLE environmental variables.  Follows is an example of
781    the disable string:
782   
783        set OSG_GL_EXTENSION_DISABLE =
784             "ATI:GL_SGIS_generate_mipmap;Sun:GL_EXT_texture_filter_anisotropic:"
785
786    New examples include:
787   
788        osgforest - an example which demonstrates simple techniques for creating forests   
789        osgfxbrowser - an example which demonstrates the various osgFX Effects available   
790        osgscalabar - an example of how to set up the osgSim::ScalarBar.
791        osgspheresegment - an example of how to set up the osgSim::SphereSegement
792        osgpagelod - a very simply test program for setting up osg::PagedLOD/osgDB::DatabasePager
793   
79423rd July 2003 - OpenSceneGraph-0.9.5
795
796    >>> Support added for OpenGL2.0 shaders, native multi-threaded Database paging,
797    >>> high peformance binary format reading and writing,  .dds compressed image
798    >>> loader and ARB_fragment_program and ARB_vertex_buffer_object extensions,
799    >>> improvements to the Terrex .txp and OpenFlight .flt loaders.
800
801    The key new features of the 0.9.5 release are the new OpenGL2.0 nodekit, constant frame rate
802    database paging support,  classes,  and the new native .ive binary plugin which supports
803    both reading and writing of all core osg nodes, including inlining of compressed
804    and non-compressed imagery.
805   
806    The native database paging support, provided by the new osg::PageLOD and osgDB::DatabasePager,
807    achieves constant frame rate through threading of the database reading, and time based
808    incremental compile and delete of display lists, vertex_buffer_objects and texture objects.
809    A new TextureObjectManager class also caches a list of expired texture objects for reuse,
810    and allows new newly loading imagery to reuse expired texture objects, with the imagery
811    automatically subloaded to the reused texture objects.  This reuse happens transparently
812    and benefits other OSG usages such as the OSG's Terrapage loader.
813   
814    To provide support multi-thread operation of the OSG, such as multi-thread database paging
815    and multi-threaded, multi-window graphics enabled by OpenProducer, the OpenSceneGraph and
816    OpenProducer have now adopted the OpenThreads threading library, osgDB and osgProducer now
817    depend upon it.  OpenThreads is open source, light weight, cross platform C++ threading
818    which encapsulates the low level, platform specific threading API calls.  Currently pthreads
819    under Unix and Win32 threads under Windows are supported, with Sgi sproc threads to be
820    released very soon.  The OpenThreads project website can be found at http://openthreads.sf.net.   
821
822    The new .ive binary plugin was developed by Uni-C's VR-Center, and kindly submitted as
823    open source, adds support for binary reading and writing OSG nodes drawable and state
824    (including compressed/mipmapped) textures.  The .ive format produces a much faster
825    load times and smaller file size then native ASCII .osg format. Load times for .ive
826    files are also 10-20x faster then equivalent OpenFlight .flt and load in an already
827    optimized scene graph form making it much more suitable for paging.  Files can be
828    converted easily using the osgconv utility : osgconv myfile.flt myfile.ive
829   
830    The new osgGL2 nodekit library adds support for the OpenGL2.0 vertex ProgramObect and fragment
831    ShaderObject's recently ratified by the OpenGL ARB, . The osgGL2 uses the extension have local
832    prototypes which allow them to be compiled even in the absence of OpenGL headers that don't
833    support the GL2 extension, allowing to port to all platform, and at runtime the extensions are
834    queried for and used if available.  At time of release only 3DLabs WildcatVP series supported
835    this extension at runtime, but other graphics cards and manufactures will be releasing GL2
836    extension very soon and will be automatically supported by osgGL2. The osgGL2 was developed
837    by Mike Weiblen at 3DLabs whom have kindly submitted osgGL2 as open source and for inclusion
838    with the OSG distribution. 
839
840    The ARB_fragment_program, ARB_vertex_buffer_object and ARB_vertex_program attributes are
841    also now supported in core osg library.  The new osg::FragmentProgram state attribute
842    encapsulates the ARB_fragment_program which is supported by the recent graphics cards
843    from NVidia, ATI and 3DLabs.  Support for ARB_vertex_buffer_object and ARB_vertex_program
844    attributes have been added to the osg::Geometry class.  The ARB_vertex_buffer_object extension
845    can boost performance by as much as 50% when working on geometry bound data sets.
846
847    Two new image loaders, dds and pnm, and a 3dc point cloud have been added. The .dds plugin
848    adds support for compressed & mipped mapped imagery, making it ideal for applications where
849    large texture sizes or database paging is required. The pnm image loader reads the
850    pnm, pgm and pbm image formats. See http://netghost.narod.ru/gff/vendspec/pbm/ for details.
851
852    The Terrapage .txp plugin  been updated to include support for multi-texturing, layers and billboards
853    and includes improvements to multi-threaded pager, which has also been ported over to use OpenThreads.
854    The OpenFlight .flt plugin has also been improved and now support detail textures via multi-texturing.
855
856    TessellationHints now supported by ShapeDrawable which allow the shape primitives to be rendered
857    are vary levels of detail.
858
859    Supported has been added for auto scaling and rotating text into osgText.
860
861    Five new examples have been included in the distribution:
862   
863        osgtexturerectangle illustrates how to use the osg::TextureRectangle which encapsulates
864        the NV_texture_rectangle extension.
865       
866        osgprerendercubemap illustrates how to use pre rendering imagery to osg::TextureCubeMap
867        for tasks such as building a environmental texture maps.
868       
869        slideshow3D is a presentation tool which use a scene graph to store a render set of slides, each
870        slide containing layers which can contain bullet points, paragraph, imagery and 3d animated
871        models - and is effectively a 3D power point. The presentations can be built separately and stored in a .osg file or created by
872        slideshow3D via an xml file, two examples - introduction.xml and models.xml, which are included
873        in the OpenSceneGraph-Data-0.9.5 data distribution.  slideshow3D depends upon libxml2 for parsing
874        the xml files.
875       
876        osgpoints uses the osg::Point state attribute to attenuate and control point size and any points
877        loaded by the application.  This is a useful way of visualizing point data clouds.
878       
879        osgdemeter is example of how to integrate the Demeter, OSG using osgProducer::Viewer as a viewer
880        class.  This example depends upon the demeter terrain engine, which can be download from
881        http://www.terrainengine.com.
882
883    Camera style convenience set and get methods to osgUtil::SceneView, consolidating
884    previous functionality that was provided by both osg::SceneView and osg::Camara into one place.
885    This move has made osg::Camera redundant so has it been removed to avoid confusion,
886    usage inconsistencies and bloat of core libraries.
887   
888    The long time deprecated osg::GeoSet has been removed, to aid migration of old .osg datasets
889    osgconv has a copy of GeoSet and the .osg support for it so is able to convert any remaining
890    .osg database which contained GeoSet's.
891
892   
893
89428th April 2003  - OpenSceneGraph-0.9.4-2
895
896    >>> Multi-threaded, multi-pipe support via integration with OpenProducer,
897    >>> 64bit Linux support for Intel Intanium and AMD Opteron,
898    >>> new osgText library with greater performance, and thread safety,
899    >>> new DDS plug-in for compressed and non-compressed images,
900    >>> new MD2 plug-in adds support for animate Quake character and
901    >>> support added for NV_texture_rectangle.
902
903    The most significant new feature is the osgProducer library that adds
904    tight integration with OpenProducer, providing the OpenSceneGraph with a
905    scalable, configurable and portable framework for developing real-time
906    and interactive graphics applications.  The scalability afforded by
907    OpenProducer allows applications to be developed which run seamlessly
908    on single pipe machines up to multi-pipe machines such as Sgi Onyx
909    IR system, and Sun Zulu systems.
910    The osgProducer/OpenProducer framework automatically handles the
911    multi-threading of cull-draw pairs and GUI events.
912
913    All the example programs have been ported over from being based on
914    GLUT to using osgProducer (osgGLUT can now be found in the bazaar
915    section on the website). The move to osgProducer allows all the examples
916    to scale from running on laptops up to multiple CPU and graphics pipe systems.
917    The configuration of threading and multiple camera views can all be done
918    via ASCII configuration files, no need to recompile.  A number of
919    new examples have also been added or revamped, bringing the total to 42.
920
921    Also in the theme of increasing scalability there is support for 64bit Linux for both
922    IA64 (Intel Itanium) and x86-64 (AMD Opteron) which compliments the existing
923    support for Solaris and IRIX 64 bit compilation.  64 bit supports allows
924    the use of very large data sets, and potential performance improvements.
925
926    To help support development teams working with multiple build configuration,
927    the makefile system has been extended to allow multiple build targets to be
928    built from one source code base.  All makefiles are also now named GNUmakefile
929    which ensures that they are only run by gmake to avoid an confusion on system
930    where gmake isn't the default make tool.
931
932    A completely new osgText implemention has been developed which is simpler
933    to use, faster, and thread safe.  Support for high quality true type fonts
934    has now been moved to a freetype plug-in which is dynamically loaded on demand,
935    with the core osgText library providing a default font when the plug-in is
936    unavailable.  Moving the freetype dependency out of the osgText library makes
937    it just dependant on OpenGL and Standard C++ like the rest of the core libraries,
938    allowing osgText to compile by default on all platforms.
939
940    Improved thread safety has also been achieved in the core osg and osgUtil libraries
941    making work on multiple CPU/multi-pipe systems robust and with improved performance.
942
943    Two new plug-ins have been added, for loading DDS and MD2 data formats. The DDS plug-in
944    is for loading compressed and non-compressed images.  The MD2 plug-in loads Quake
945    animated characters.
946   
947    osg::TextureRectangle class has been added, which encapsulates the
948    NV_texture_rectangle and EXT_texture_rectangle extensions.  This is particularly
949    useful for render to texture algorithms, and dynamic paging of images such as for
950    rendering video streams.
951
952    Support for automatic subloading of osg::Texture2D textures has been added
953    so that when image data is updated the corresponding OpenGL texture is
954    automatically updated - no need for callbacks.  Also added to the osg::Texture
955    classes is the option of automatic unref'ing of texture image data once the data has
956    been download to all active OpenGL graphics contexts.
957   
958    A new osgUtil::DelaunayTriangulator utility class has been added.  This is ideal for
959    creating optimal triangular meshes from unconnected data points.
960
961    Two new classes, osg::ArgumentParser and osg::ApplicationUsage, have been introduced
962    to convineiently and robustly parse command line arguments and
963    report command line usage, environmental variables and keyboard and mouse bindings
964    used by applications.  Running any of the examples with -h or --help will report
965    full details example usage.  Keyboard and Mouse bindings usage is now also available as
966    a HUD on all examples, simply press 'h' while the app is running to
967    bring up help.
968
969    A database cache in the osgDB library has been added, along with a clean up
970    of memory management in the OpenFlight loader, make development of
971    dynamic paging of databases easier and more robust.
972   
973    Support for early abort of rendering has been added, which is useful for
974    interactive applications which occasionally have rendering that takes that long
975    enough (i.e.several seconds) that end users may wish to abort during the drawing.
976
977    There have also been many general API improvements and bug fixes, too many to enumerate,
978    but all go to solidify the quality of the scene graph and its accompanying libraries. 
979   
980    The combination of new features, robustness and scalability mark this release as a
981    significant step towards 1.0.

1025    named now does update, cull, draw.  The AppVisitor, set/getAppCallback etc
1026    have be renamed UpdateVisitor, set/getUpdateCallback etc.
1027
1028    Removed the osg/ManagerManger and associated #define osgNew's, this has
1029    been done to simplify users code and to solve the lack of thread safety

1048    From Geoff Michel, AC3D .wc and Carbon Graphics GEO .geo loaders.
1049
1050    Support for multi-texturing added to OpenFlight loader.
1051   
1052    LOD has been revamped to allow independent min and max ranges for
1053    each LOD child, bringing it inline with the OpenFlight style LOD
1054    representation.
1055
1056    Switch has been revamped to allow independent switching on or off of
1057    each Switch child, bringing it inline with the OpenFlight style Switch
1058    representation.
1059
1060    New osg::Shape geometry primitives added which allow the specification
1061    of geometry in a form that can accelerate collision detection, and as
1062    a way of specifying the geometry to tessellate.  Shapes include
1063    Sphere, Oriented Box, Cone, Cylinder, Grid, TriangleMesh, ConvexHull
1064    and CompositeShape which allows the storage of a hierarchy of shapes.
1065   
1066    Geometry has been extended to all per primitive bindings and
1067    per primitive set bindings of attributes, and indexing of attributes
1068    with the same or different index lists for each attribute list.
1069
1070    From Macro Jez, new cubemap helper classes.
1071
1072    Support added for handling different extensions on different graphics
1073    contexts.
1074
1075    Draw and Sort callbacks added to osg::RenderStage.
1076
1077    Added PolygonStipple class.
1078   
1079    Further refinement of class names and method calls:
1080    Renamed classes :
1081   
1082        Primitive    -> PrimitiveSet
1083       
1084    Renamed methods :
1085   
1086        Geometry::addPrimitive(..) -> addPrimitiveSet(..)
1087        Drawable::drawImmediateMode(..) -> drawImplementation(..) const
1088        Drawable::DrawCallback::drawImmediateMode(..) -> drawImplementation(..) const

109130th August 2002 - OpenSceneGraph-0.9.1.tar.gz
1092
1093    >>> 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!
1094
1095    Despite only 6 weeks passing between 0.9.0 and this latest 0.9.1 release
1096    there has been a number of significant new features, API clean ups and
1097    bug fixes.  Follows is a quick run through the key improvements.
1098
1099    Addition of osg::Texture1D, Texture2D & Texture3D classes, Texture2D replaces
1100    the original osg::Texture, which has now become a pure virtual base class. All
1101    Texture classes, including TextureCubeMap are derived from this base class..
1102   
1103    New osgtexture1D and osgtexture3D demos demonstrate the new texture classes in
1104    action.
1105   
1106    The build system has been updated to support HP-UX.  This adds one of the last
1107    remaining mainstream platforms supported.
1108
1109    A new Inventor/VRML1.0 loader was added.  The inventor format has been requested
1110    on numerous occasions, so this is a welcome addition.
1111   
1112    Support added to lwo plugin for loading the new lwo2 format.
1113
1114    osg::TexEnvCombine implemented texture_env_combine and texture_env_crossbar
1115    and texture_env_dot3 extensions.
1116
1117    osg::TexEnv texture_env_add added.
1118
1119    A osg::Sequence node has finally been implemented.  It is accompanied by a
1120    demo, osgsequence.
1121
1122    osg::DOFTransformNode implemented.
1123
1124    Support for OpenFlight15.7 added, DOFTransforms and general enhancements and
1125    bug fixes.
1126
1127    New PROTECTED mode for protecting local state mode and attributes from be
1128    overridden from state above it in the scene graph.
1129   
1130    Support for fog coord and secondary colors extensions added to osg::Geometry.
1131
1132    osg::Billboard has been improved to allow rotations around all axes, as well
1133    as point rotations.  Check osgbillboard for a new improved demo.
1134
1135    The osglight example has been improved by utilizing AnimationPath and
1136    PositionAttitudeTransform to keep light sources in motion.
1137
1138    osg::AnimationPath improved, now allowing swing and looping behavior and
1139    with two new app callbacks which can update PositionAttitudeTransform
1140    and MatrixTransform respectively.
1141   
1142    Support for writing osg::Image's to .rgb format added.
1143
1144    To keep the overall API clean, and the following items have been
1145    renamed and deprecated parts of the API have been removed:
1146
1147    Renamed classes:
1148
1149            EarthSky        -> ClearNode
1150            Transparency    -> BlendFunc
1151            Texture         -> Texture2D  (old style subload parameters removed)
1152
1153    Method's changed
1154
1155            Matrix          -> makeRotate(..) euler angles parameters generalized.
1156            Quat            -> makeRotate(..) euler angles parameters generalized.
1157
1158            BoundingBox     -> isValid() renamed valid()
1159            BoundingSphere  -> isValid() renamed valid()
1160
1161            StateAttribute  -> OVERRIDE_OFF & OVERRIDE_ON which were short hand
1162                               versions of OVERRIDE | OFF and OVERRIDE | ON
1163                               removed, as the meaning of the bitmask was
1164                               often confused by the short hand notation.
1165
1166
1167            Transform       -> setMatrix/getMatrix() etc methods removed,
1168                               Transform becoming the transform base class,
1169                               with MatrixTransform taking over all the original
1170                               functionality.
1171

117319th July 2002 - OpenSceneGraph-0.9.0.tar.gz
1174
1175    >>> OpenSceneGraph goes beta - Multitexturing, Occlusion Culling, Particles and much more added!
1176
1177    This release marks the beginning of the beta phase of the OpenSceneGraph
1178    development, which means that all the major core features are now
1179    in the scene graph, and 1.0 is not far away.  Its performance, features
1180    and portability already compares very favorably to other scene graphs,
1181    both comerical and open source. 
1182
1183    Multi-texturing support added to osg::StateSet, osg::Geometry, osg::State
1184    and txp loader, so multi-texturing can now be done with very little coding
1185    from the user - all you need to do is specify the texture unit to use
1186    when setting texturing state and texture coordinates and the rest is
1187    handled automatically by the scene graph!
1188   
1189    The new osg::Geometry classes which supersedes the old Performer style
1190    osg::GeoSet, support multi-texturing, and uses sharable osg::Arrays which
1191    utilize std::vector<> for data storage and manipulation.
1192
1193    Shadow volume occlusion culling adding to the core OSG, developed as a
1194    collobaration between Mike Connell and Robert Osfield. Our implementation
1195    uses convex planer occluders, with support for holes to allow larger
1196    and more effective occluders to be used. The approach is software
1197    based so it 100% portable, and by culling during the cull traversal
1198    both CPU and GPU loads are significantly reduced, making it an extremely
1199    powerful feature for large scale urban and indoor visulisation.
1200
1201    osgParticle developed by Marco Jez adds support for a range of particle
1202    effects such smoke, fires, engine plumes, fountains, fire works, and
1203    is fully customizable to produce your own favorite effects. osgParticle
1204    is a NodeKit (see below) which can be directly linked to in your
1205    application to allow you to create particle effects by hand, or have
1206    the library dynamically loaded in when you load a database which contains
1207    particle effects.
1208   
1209    osgGA (Gui Abstraction) library written by Neil Salter adds classes for
1210    adapting different GUI toolkits to work with a standard set of manipulators for
1211    modifying the scene, such as camera and state manipulators.
1212   
1213    Support has been added to the plugin architecture to facilitate the
1214    development of NodeKits - add on libraries which can used directly
1215    in your code, or loaded indirectly when loading from file.  The
1216    later allows you to load a .osg file with text or particle effects
1217    in them,the plugin architecture automatically loads the required
1218    library which supports these features.
1219
1220    A range of new demos have been as code examples, and to demonstrate
1221    the range of features that OpenSceneGraph delivers:
1222
1223        osgoccluder  - demonstrates ocllusion culling, and has a mode
1224                       which allows the users to interactively create
1225                       their own convex planer occluders.
1226        osghud       - how to mix head up display with 3d views.
1227        osgparticle  - shows the new osgParticle node kit in action.               
1228        osgprerender - pre renders and scene then textures the result onto
1229                       an animated flag.
1230        osgcallback  - examples of the full range of callbacks that you
1231                       can use to add dynamic behaviors to your scene graph.
1232        osglight     - a simple example of how to set up spot and position
1233                       lights in the scene.
1234        osgclip      - illustrates how to add clip planes to you scene.
1235        osggeometry  - examples of the different ways to set up primitives
1236                       and vertex/color/normal and texture attributes in
1237                       the new osg::Geometry class.
1238        osgmultitexture - a simple example which adds a spherical reflection
1239                        map to a whole scene using the second texture unit
1240                        if one exists.
1241       
1242    osg::Drawable::PrimtiveFunctor has also been added to allow querrying
1243    of primitive data with Drawables subclasses without requiring knowledge
1244    of the types of Drawable subclasses that exists.  This decoupling makes
1245    it a very powerful and flexible utility.
1246

1249
1250    >>> Support added for Solaris, texture cube mapping & muliple projections.
1251   
1252    The OpenSceneGraph now has a new Makefile system which supports all Unix
1253    compilation including the new addition to the family - Solaris! 
1254
1255    OpenSceneGraph welcomes Solaris to the list of supported platforms.  This
1256    release puts all of the OpenSceneGraph functionality at the fingertips of
1257    Sun Microsystem's customers and developers.  Solaris users can now have
1258    the benefit of a high performance scene graph for visual simulation,
1259    virtual reality, scientific visualization, CAD, and architectural
1260    walk-throughs.  Many thanks to Sun for providing resources for the port.
1261   
1262    Additional html documentation has been added to the distribution to
1263    make it easier to get an understanding of scene graph technology and
1264    the project itself and how to make use of it. 
1265
1266    Support has also been added for OpenGL's texture cube mapping which
1267    is ideal for accurate environmental reflections and much more.
1268   
1269    The scene graph has been extended to allow multiple projection (via
1270    the new osg::Projection node) and viewports within one scene graphs,
1271    this makes it much easier to set up head up displays, and we have
1272    an example to demonstrate how easy it is - osghud.
1273   
1274    The osgUtil::CullVisitor and osgUtil::SceneView has been revamped
1275    removing the dependency on osg::Camera, which is now simply an
1276    option for SceneView rather than a requirement.  This allows users
1277    to set the camera entirely with the scene graph or create their own
1278    camera classes and use them with SceneView.  The existing osg::Camera
1279    has also been simplified as support for setting projection and
1280    modelview matrices have been moved out to the cull traversal.
1281   
1282    Several sets of node callbacks have been added, including a Cull
1283    NodeCallback on each Node, ComputeTransformCallback on Transform
1284    Nodes, EvaluateLODCallback on LOD nodes, ComputeBillboardCallback
1285    on Billboard nodes.  These make it my easier to customize the
1286    scene graphs behavior at runtime.
1287   
1288    osg::Image::readPixels() and support for writing .bmp files has been
1289    added which has made it easy to add screen capture the any OpenSceneGraph
1290    application.  This feature is demonstrated in the scene graph viewer
1291    which comes with the distribution - just press 'O' to output a screenshot.
1292   
1293    Finally, include/osg/MemoryManager has been added which overrides new
1294    and delete for debug builds. The override new and delete track allocations
1295    and deallocations, ensure they are matched, checked for memory under and
1296    overruns, and outputs a memleaks.log file on the results of executing
1297    your applications.  This help track down a number of memory leaks and
1298    unmatched new and deletes within the OpenSceneGraph and should make
1299    it easier to do with users applications as well.
1300   
1301    All in all, the OpenSceneGraph is now more portable, easier to
1302    customize, cleaner and more robust.  Beta release and 1.0 is now not
1303    far away!
1304   
1305
130624th February 2002 - osg-0.8.44.tar.gzosg-
1307
1308    >>> Support added for Mac OSX, Cygwin and MinGW, and new TerraPage loader.
1309   
1310    The major item for this release is the completion of the Mac OSX port,
1311    thanks to Phil Atkin and others for making this happen.
1312   
1313    Also added to support for Cygwin and MinGW builds which gives Windows
1314    users a free and robust alternative to the Visual C++, which we
1315    have Norman Vine to thank.
1316   
1317    Funtionality wise there has been a great deal of work behind the scenes
1318    putting in place a flexible and extensible framework for handling
1319    transform nodes, users can now extend the osg::Transform node through
1320    subclassing or via callbacks.  This work will underpin future work
1321    on moving camera setup into the scene graph, and environmental effects
1322    such as cloud layers, ground planes, stars and earth sky implementations
1323    which are planned for the next release.
1324   
1325    Callbacks and virtual methods have also been added to the osg::LOD &
1326    osg::Billboard to allow users to customize their behavior.  Draw
1327    callbacks have also been added to allow customization of osg::Drawables
1328    at runtime.
1329   
1330    The Open Flight .flt loader has undergone a number of improvements
1331    including support for instancing and billboards.
1332   
1333    New TerraPage (.txp) loader and OpenDX writer (.dx) plugins have been added.
1334   
1335    Support for the clone operation on osg::Object's has been expanded
1336    to allow cloneType() - a simple clone an blank object of the same type,
1337    and clone(CopyOp&) where CopyOp is a functor which allows users to
1338    specify the deep copy vs shallow copying of object data.
1339   
1340
13412nd January 2002 - osg-0.8.43.tar.gz
1342
1343    >>> Support for TrueType text, Stereo out of the box, and much more.
1344   
1345    Since the last release the OSG has moved to CVS based developments so
1346    many users will have seen gradual increments in functionality and changes
1347    to the API. Whereas a the leap from 0.8.42 to 0.8.43 is actually quite
1348    significant is likely to require code changes as several significant parts
1349    of the API have evolved to a more mature state.
1350   
1351    The most significant new functionality is the addition of the osgText
1352    library which provides support for true type font rendering, as textured,
1353    polygonal, pixmap, bitmap and 3D fonts.
1354   
1355    We now have new osg::Matrix implementation which cleans up its interface.
1356    Also all angular parameters are now based on radians rather than degrees
1357    as before (and as in Performer), this has been done to be more consistent
1358    with the basic trignometric functions and standard maths conventions.
1359   
1360    Scene graph optimization has been added which can boost performance
1361    on some database by as much as an order of magnititude, this is
1362    particularily noticable in .flt based databases.  Display list performance
1363    has also been boosted on NVidia based machines thanks to changing the
1364    compilation and execution of display list into two seperate operations.
1365   
1366    App callbacks are now supported on all Nodes, and there now a proper
1367    app traversal which can be used to animate the scene.
1368   
1369    Stereo support has been added into the osgUtil::SceneView which allows
1370    quad buffered/anaglyphic stereo to enabled easily for almost all OSG
1371    applications without code modifications - simple set environmental
1372    variable or pass in appropriate arguments and your app will render in
1373    stereo!
1374
1375    src/Demos/osgcluster has been added to demonstrate how easy it is
1376    to set up a graphics cluster across a standard networked PC's.
1377
1378    There have been many minor code changes to fix bugs and address
1379    performance bottlenecks or to improve extensibility was, representing
1380    a significant step towards API maturity and a beta release which is
1381    now not far away.
1382

13849th August 2001 - osg-0.8.42.tar.gz
1385
1386    >>> New osgWX library for integration of OSG with wxWindows apps.
1387
1388    This release sees a relatively minor number of enhancements over
1389    0.8.41, the most significant being the new osgWX library and wxsgv
1390    demo written by Ben Discoe.
1391   
1392    Also from Brede Johansen in this release is the improvements in support for older
1393    .flt (Open Flight) files such versions 12 & 13.  Previously only version
1394    15.6 files had been tested and developed to.
1395   
1396    Last but by no means least, several bug fixes related to view frustum
1397    culling have been made.
1398
1399
140025th July 2001 - osg-0.8.41.tar.gz
1401
1402    >>> Support added for multi-pass and multi-stage rendering including Impostors.
1403
1404    The key feature developed is a highly flexible framework for multi-pass and
1405    multi-stage rendering techniques.  Unlike most scene graphs and games
1406    engines the OSG has as dynamic framework which automatically configures
1407    itself at runtime.
1408
1409    Building ontop of the new framework's multi-stage rendering capabilities,
1410    support for Impostors (hirachical image caching) has been integrated into
1411    the core scene graph  library making extremely easy to take advantage of
1412    this advanced rendering techinque - normally only seen in research papers.
1413    Check out osgimpostor demo to see how easy it is to add osg::Impostor
1414    nodes to your own models. Impostors are particularily effective are
1415    reducing scene complexity whilest minimizing the visual impact, making it
1416    ideal for scenes with large numbers of complex objects such as a city
1417    scene, or a dense forest.
1418   
1419    Taking advantage of the new framework's multi-pass rendering capabilities
1420    is osgreflect demo which illustrates how to achieve planar relfections
1421    using the stencil buffer and multi-pass rendering.
1422   
1423    The cool thing about both the osgreflect and osgimpostor demos is that
1424    there is no hardwiring to achieve the results, the scene graph stores
1425    all the information neccessary to specify the number and type of rendering
1426    passes, and the framework handles the rest behind the scenes.  This also
1427    makes it very easy to add these advanced rendering techinques to your
1428    own applications as everything is cleanly encapsulated with
1429    osgUtil::SceneView.
1430
1431    New loaders have been added to support .lwo (Light Wave), .obj
1432    (Alias Wavefront) and .dw (Design Workshop) 3D file formats making it
1433    even easier to compose your own worlds from models sourced from the
1434    web or your own.
1435   
1436    osg::Camera has been totally revamped and now supports asymetric
1437    and othographics projections in addition to the symetrical perspective
1438    projections.
1439
1440    And finally, support for texture subloading has been added to osg::Texture
1441    and osg::Image.  This allows textures to be updated dynamically, and
1442    has already been used for mpeg video playback!   
1443

1446
1447    >>> Project lead, Robert Osfield, makes full-time commitment to OSG.
1448
1449    This is the first full release since project lead, Robert Osfield, made
1450    a move to pursue the OSG's development full-time.  This commitment has
1451    been made to bring the API rapidly towards maturity, and to provide
1452    high quality support and consultancy services.  Please contact
1453    robert@openscenegraph.com if you have any queries.
1454
1455    This release marks a significant step forward in the maturity of the
1456    API, with several major changes to the library in the areas of state
1457    handling, database support, and portability.
1458
1459    To improve the extensibility of the OSG's handling of OpenGL state,
1460    new classes have been introduced to replace the previous hardwired
1461    state handling classes.  The new classes also allow improved state
1462    sorting and lazy state updating which boosts both cull traversal
1463    and particularly draw traversal performance.
1464
1465    To improve the modularity, interopability and conceptual clarity the
1466    support classes for database loading have been moved from the core
1467    osg library into their own osgDB library.  Support for the .osg
1468    ASCII native database format and the .rgb reader has moved into its own
1469    osgPlugins library to further the cleanliness of the core library.
1470
1471    Support has be added for multiple OpenGL context's and hence multi-pipe
1472    systems such as sgi's Onyx2, allowing each context to have its own
1473    display list and texture objects.
1474
1475    The culler and rendering support in osgUtil has also been improved, and
1476    significantly speeded up for complex models.
1477
1478    Also just in, thanks to Randall Hopper for adding support for FreeBSD :-)

1485    The first steps towards support of MacOS have been taken by Bryan Woods,
1486    adding Metrowerks project files and adding support for MacOS into the
1487    core scene graph.  Work still in progress so assistance welcome to
1488    complete the task.
1489
1490    Other major developments have been the addition of two new base classes
1491    osg::StateAttribute and osg::Drawable which are designed to allow greater
1492    extensibility of OpenGL state management and primitives.

1497    >>> New 3DS loader added
1498
1499    The OpenSceneGraph now supports the 3DS file format. This makes
1500    available a huge range of potential models. Check out
1501    http://www.3dcafe.com or http://www.3drocketfuel.com for some juice.

1504
1505    >>> Texture compression now supported
1506
1507    The OpenSceneGraph now provides support for ARB and S3TC texture
1508    compression. This allows more textures to be loaded onto graphics
1509    card memory, resulting in happier users and a better world in which
1510    to live.
1511
1512    This release also sees the addition of a simple hang gliding flight sim
1513    demo.

1516
1517    >>> Anisotropic texturing now supported <i>and</i> loading of gzip compressed files
1518
1519    Anisotropic texturing provides for the next step in quality texturing
1520    filtering above tri-linear and is especially effective when viewing
1521    texture surfaces at shallow angles.
1522
1523    Also added in this release is on-the-fly support for loading gzipped
1524    (.osgtgz, .tgz) and zipped (.zip) database files.  This features allows
1525    users to store whole databases (models and textures) in a single
1526    tar ball and unpack them automatically on running the osg.  This
1527    is ideal for browsing the web.

1530
1531    >>> Support added for OpenGL vertex arrays, and several key image loaders.
1532   
1533    Support for OpenGL vertex arrays has been added to improve performance,
1534    particularly accelerating PC based graphics.
1535
1536    Also added is support gif, jpeg, pic, tga, tiff image formats via
1537    dynamic plugins.

1541    >>> New high resolution, low latency timer class - osg::Timer.
1542
1543    Real-time graphics relies upon accurate timers for updating physics
1544    simulations and managing constant framerates.  The OSG now provides
1545    osg::Timer which, when supported, takes advantage of hardware timers.

1549
1550    >>> Support for detail drawing with osg::PolygonOffset.
1551
1552    Rendering of polygons which overlay underlying geometry, such
1553    as white lines on a runway, can now be achieved utilizing the
1554    new osg::PolygonOffset which encapsulates glPolygonOffset to
1555    avoid z fighting which otherwise hampers such detailing.
1556
155710th November 2000 - osg_src-0.8-28.tar.gz
1558
1559    >>> New Open Flight .flt loader!
1560
1561    Thanks to Brede Johansen submission of .flt loader, the OSG can now
1562    read Open Flight .flt databases.
1563
15643rd November 2000 - osg_src-0.8-26.tar.gz
1565
1566    >>> Driving and Flight modes have been added to viewers.
1567
1568    osgUtil::DriveManipulator and osgUtil::FlightManipulator have been
1569    added to allow the scene graph viewer (sgv) and other viewers to
1570    support a drive and flying modes.  These modes can be accessed
1571    in sgv by pressing '2' and '3' respectively ('1' returns to
1572    trackball manipulator).  Left mouse button accelerates forward,
1573    middle stops motion and right deccelerates.
