The framework makes it possible to easily create rich virtual environments with rigid-body dynamics, advanced rendering using OpenGL Shaders, 3D sound and human avatars. The creative process of building complex simulators is supported by allowing several authoring paths such as a low level C++ API, an expressive high level file format and a scripting layer.Categories and Subject Descriptors: I.3.4 [Graphics Utilities]: Software support
