Projects / OpenSG


OpenSG is an Open Source scenegraph system. Its design goals include high performance, multithread-safe data handling, high flexibility, extensibility, and portability to Irix, Linux, and Windows. A number of computer graphics research institutions are actively working on moving the system beyond the state of the art to include features like clustering, subdivision surfaces, occlusion culling, and more.
