graphic contexts and multi-threading. NodeKits Project distribution also contains a variety of so-called NodeKits. These are solutions of common problems and frequently used more advanced 3D application components and graphics algorithms. Among the most significant are osgAnimation — Skeletal models usage, animating and morphing. osgFX — Special effects and image postprocessing. osgManipulator — Interactive 3D scene manipulation. osgParticle — Advanced particle system usage. osgQt — Integration with Qt toolkit and incorporation of QtGUI elements into OSG applications. osgShadow — Framework for shadow rendering techniques. osgTerrain — Extensive terrain rendering. osgText — Quality antialiased fonts, TrueType and FreeType font support. osgVolume — Volume rendering and volumetric data manipulation. osgWidget — Simple GUI creation. Reception and adoption OpenSceneGraph doesn't provide any functionality for higher "gaming" logic, it is a rendering-only tool. There are several full-scale engines for computer games (or so-called serious games) creation using OSG as a base of graphics rendering, the most common framework being Delta3D. There is a great variety of software products built on top of OpenSceneGraph; among others, Virtual Terrain Project and ViewTec TerrainView. List of OSG users contains companies as Boeing, NASA, FlightGear, Norcontrol and many others. At the opensource community level, several projects have adopted OSG as a rendering backend: FlightGear (Flight Simulation software) OpenMW (Open-source engine recreation for Morrowind) OpenSceneGraph has received a javascript/WebGL implementation called OSG.JS that is used by many online 3D scene viewers including Sketchfab and Clara.io. A wrapping from C++ to javascript through Emscripten OGStudio is also currently developed. Among other products that use OSG must be mentioned: Remo 3D OSG Scene Editor See also OSG.JS OpenGL OGRE Delta3D Irrlicht Engine Crystal Space Visualization Library OpenSG ossimPlanet Grome Open Inventor Unity (game engine) References External links - official website for the project AlphaPixel OSG Binaries - Windows, Mac and Linux x86 and x64 precompiled binaries.
