YafaRay is a free open-source raytracing engine. Raytracing is a rendering technique for generating realistic images by tracing the path of light through a 3D scene. A render engine consists of a "faceless" computer program that interacts with a host 3D application to provide specific raytracing capabilities "on demand". Blender 3D is YafaRay main host application at the moment. The YafaRay engine is released under the LGPL 2.1 license. You can download YafaRay binaries and the source code in the downloads section.
