PERTHSHIRE, Scotland - 15th June 2007 - OpenSceneGraph Professional Services announces the release of OpenSceneGraph 2.0, the industry's leading open-source scene graph technology, designed to accelerate application development and improve 3D graphics performance. 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.

Open-source development delivers industry-leading features and performance

The 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.

The theme for the 2.0 release has been making the OpenSceneGraph easier to use, yet more flexible and powerful.

Features include:

  • New unified build system using 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.
  • New libraries:
    • 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 the osgProducer/Producer combo as viewer toolkit.
    • osgManipulator - provides a set of interactive manipulators for scaling, rotating and moving objects in the scene.
    • osgShadow - provides an extensible framework for adding dynamic shadows to your scene.
  • New low-level extensible intersection framework that includes support for line, plane and polytope intersections.
  • New high-level intersection classes that support paged databases, LineOfSight, HeightAboveTerrain and ElevationSlice.
  • View-dependent overlay - provides ability to overlay text, country boundaries etc. directly on to terrain, even paged databases.
  • Plugins
    • Improvements to the OpenFlight, COLLADA, AC3D, DDS plugins and many more
    • New TXF texture font reader.
    • New VRML2 reader (using the OpenVRML library).
  • Easier 3rd party windowing integration
    • With examples showing integration with GLUT, SDL, Qt, WxWidgets and MFC
  • External dependencies removed simplifying build and distribution
    • OpenThreads is moved into the core of OpenSceneGraph and is no longer an external dependency
    • Thanks to the integration of windowing support in osgViewer, Producer is no longer a dependency.

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 openscenegraph.org 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 and OpenSceneGraph Reference Manuals are now available and up to date with the latest OpenSceneGraph-2.0 release. To purchase your copies head over to OpenSceneGraph Books website. Profits from the books will help fund further documentation and book efforts.

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.

  • Confidential Professional Support
  • Bespoke development
  • Consultancy
  • Training

Community support and contributions

The diverse and growing community of over 1700 developers is centered 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 264 individuals from around the world that have directly contributed to the development and refinement of the OpenSceneGraph code base.
