This project is in the field of Computer Graphics. It provides C++ classes to compute accessibility shading on 3D objects. It uses ray tracing to compute accessibility values and stores the result in 2D textures maps.
RTE is a global illumination engine used for lighting scenes in an interactive 3D environment. It can compute the global illumination, both on the fly or as a pre-compute process. It can be easily tied to existing Scenegraphs/3D rendering engines/games.
