PERTHSHIRE, Scotland - 5th August 2008 - OpenSceneGraph Professional Services announces the release of OpenSceneGraph 2.6, the industry's leading open-source scene graph technology, designed to accelerate application development and improve 3D graphics performance. OpenSceneGraph 2.6 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 that eclipses commercial scene graph toolkits in functionality, stability and performance. OpenSceneGraph 2.6 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 2.6 release is the culmination of 9 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 include:

  • New osgWidget library for scene graph based graphics user interface elements (beta release).
  • KdTree support, with automatic KdTree generation on load and use of KdTree during line intersections which massively improves intersection speeds.
  • Precision improvements to line intersections, provide accurate whole earth intersection.
  • OpenGL Multi-sample FrameBufferObject support.
  • New osg::ImageSequence class for doing texture animation of a series of image files.
  • New database optimizer that is able to remove static transforms by duplicating shared geometries.
  • Use glGenerateMipmap to speed up mipmap generation in non power-of-two textures.
  • New osgViewer::ScreenCaptureHandler for adding screen shot support to osgViewer applications.
  • New osgscreencapture example that demonstrates use of double buffer PixelBufferObject?'s for streaming of imagery from the screen.
  • New utility application osgfilecache which can be used to populate the local cache for given lat/lon ranges and levels.
  • Rewritten DatabasePager that now supports multiple database reading threads. This includes handling of HTTP requests via a separate reading thread, vastly improving the speed of updates when handling HTTP hosted databases that have already partially been downloaded to local file cache.
  • Support for a file cache for locally caching paged databases hosted over HTTP.
  • Support for http authentication in osgDB and the libcurl plugin
  • New osgconv --format <fmt>, --formats and --plugins command line options for listing available plugins and the file formats/options they support.
  • Performance improvements in handling TerraPage.
  • Animated GIF support.
  • New SVG image loader.
  • Improvements to the .obj loader to support a wider range of .obj files and material properties.
  • Support for thread safe Atomic reference counting.
  • Support for COLLADA DOM 2.x
  • Support for Philips WOWvx 3D auto-stereoscopic displays
  • New include/osg/Config and include/OpenThreads/Config configuration files, that are automatically generated by CMake, which make more straight forward to build end users applications against OpenSceneGraph versions built with non default build options.
  • Support for CMake 2.6
  • A wide range of build and bug fixes

Downloads and Licensing

OpenSceneGraph is open-source so full source code is provided, and can be copied, modified and used free of charge for commercial and non-commercial use. Access to the source allows end users greater flexibility in how they develop, debug and deploy their applications. They gain productivity and freedom by being able to leverage the tool chain in accordance with their own release cycles. Downloads of binaries and source can be found in the Downloads section of the website.

OpenSceneGraph is released under the OpenSceneGraph Public License, which is based on the Lesser GNU Public License (LGPL), permitting the software to be used free of charge across the full spectrum of commercial and open-source applications. Furthermore, it allows both static and dynamic linking of the OpenSceneGraph libraries without restricting the licensing of the user's software.

OpenSceneGraph Books now available

The OpenSceneGraph Quick Start Guide is now available in Chinese as well as English, and alongside the Reference Manual books can be found at OsgBooks.

Professional support and services

OpenSceneGraph project is backed up with professional services by OpenSceneGraph Professional Services, based in Scotland, and Skew-Matrix and Blue-Newt Software both based in the USA, and a range of Contractors from around the world. Services available include:

  • Confidential Professional Support
  • Bespoke development
  • Consultancy
  • Training

Community support and contributions

The diverse and growing community of over 1900 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 324 individuals from around the world that have directly contributed to the development and refinement of the OpenSceneGraph code base.
