algorithm, which is famous for its high speed and efficiency in handling even very large scenes, and has good support for displacement shaders. Like many other open source projects, Aqsis is hosted on SourceForge and is in continuous and active development.
Because of its Reyes heritage, Aqsis lacks some advanced global illumination features like ray tracing, although active efforts are underway to support some such features. Its Current stable version is 1.4 & supports nearly all rendering features.
