PERTHSHIRE, Scotland - OpenSceneGraph Professional Services announces the release of OpenSceneGraph 2.8.1, the industry's leading open-source scene graph technology, designed to accelerate application development and improve 3D graphics performance.
OpenSceneGraph 2.8 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 eclipses commercial scene graph toolkits in functionality, stability and performance. OpenSceneGraph 2.8 runs on all Microsoft Windows platforms, Apple OS/X, GNU/Linux, IRIX, Solaris, HP-UX, AIX and FreeBSD operating systems.
Open-source development delivers industry-leading features and performance
The OpenSceneGraph 2.8.1 release is the culmination of 10 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.
Updates between 2.8.1 and 2.8.0 releases include:
* Build fixes under !FreeBSD and IBM AIX, and RedHat Enterprise Linux.
* Improved compatibility with SWIG wrapper building
* Crash fixes in osg::State, osg::Geometry and osgWidget.
* Bug fixes to :
o draw instanced support
o Optimizer - MergeGeometryVisitor, RemoveLoadedProxyNodesVisitor and SpatializeGroupsVistor
o hdr image loader
o handling of opacity maps in 3ds loader
o dxf loader
o frame buffer object
o cursor/event handling in windows
o windows threading
o memory leak in Collada loader
o fixes to display lists/vbo creation that prevent crash under ATI drivers
o subface PolygonOffset setting in OpenFlight
o osgconv --formats under OSX
o osgTerrain::Layer bounding volume calculation.
Updates between 2.8 and 2.6 include:
* New osgVolume library for volume rendering, with support for:
o High quality GPU based Ray tracing
o Transfer functions
o Per pixel lighting
o Iso surface rendering
o Maximum Intensity Projection rendering

o VNC client widget (based on libVNCServer)
o Internet browser client widget (based on Gecko/UBrowser)
* New plugins for loading Half-Life 2 maps and models.
* New plugin for loading EXR, high dynamic range imagery
* Improvements to DatabasePager, tailored for low latency paging.
* Improved runtime stats collection and on screen reporting.
* Performance improvements through optimization of matrix operations.
* Support for the OpenGL "draw instanced" extension.
* Support for zlib compressed native .ive and .gz files
* Improvements to COLLADA support.

Community support and contributions
The diverse and growing community of over 2000 developers is centred around the public osg-users mailing list, where members discuss how best to use OpenSceneGraph, provide mutual support, and coordinate development of new features and bug fixes. Members of this community come from many different countries with backgrounds ranging from some of the world's largest aerospace companies, game companies, and visual simulation specialists to university researchers, students and hobbyists.
The OpenSceneGraph project owes a great deal to the community for its development and support, in particular we wish to thank the 372 individuals from around the world that have directly contributed to the development and refinement of the OpenSceneGraph code base.
