YafaRay is a free open-source montecarlo raytracing engine released under the LGPL 2.1 license. 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 specialised computer program that interacts with a host 3D application to provide specific raytracing capabilities “on demand”. The YafaRay engine can be used in the following 3D applications: Blender, Edificius, pCon-planner and Wings 3D.
