OpenSceneGraph is an open source 3D graphics application programming interface, used by application developers in fields such as visual simulation, computer games, virtual reality, scientific visualization and modeling. The toolkit is written in standard C++ using OpenGL,〔 and runs on a variety of operating systems including Microsoft Windows, Mac OS X, Linux, IRIX, Solaris and FreeBSD. Since version 3.0.0, OpenSceneGraph also supports application development for mobile platforms, namely iOS and Android. == History == The OpenSceneGraph project was initiated by Don Burns in 1998. Robert Osfield joined the project during 1999, working on porting finished components for Microsoft Windows. The project went open source in September 1999 and the official (project website ) was created. Towards the end of the year Osfield took over the project and began extensive refactoring of the existing codebase, putting emphasis on modernisation, embracing modern C++ standards and design patterns. In April 2001, taking into account growing community of users and interest of public, Robert Osfield created OpenSceneGraph Professional Services, providing commercial support, consulting and training services. This marks full professionalization of the project. The first official stable version of OpenSceneGraph was version 1.0, released in 2005. An extended version 2.0 followed in 2007, adding support for multi-core and multi-gpu systems, several important NodeKits and usage of unified multiplatform build system CMake. Books and user handbooks were introduced.〔Martz, P.: OpenSceneGraph Quick Start Guide. Louisville, USA, 2007.〕 The project has been quickly growing and becoming more popular ever since. There are more than 530 contributors signed under current stable version, and the official mailing list contains thousands of names.〔http://www.openscenegraph.org/projects/osg/wiki/Support/History〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「OpenSceneGraph」の詳細全文を読む スポンサード リンク
