Extensions:Render engines/Yafaray
YafaRay is a open source raytracing render engine. As an open source software project, users and developers have free access to the source code and it is free, as in free speech.
Ray tracing is a rendering technique for generating an realistic image by tracing the path of light through the 3D scene. This technique tries to reproduce the natural behaviour of light and its particular effects on surfaces, such as reflection and refraction, caustics and indirect lighting.
YafaRay works as a render engine. An engine consists of a computer program that interacts with a host 3D application to provide very specific raytracing capabilties 'on demand'. Blender 3D is the host application of YafaRay.
