A YafRay rendering of piston engine parts modelled in Blender.
YafRay (Yet Another Free Raytracer) is an open source ray tracing program that uses an XML scene description language. It has recently been integrated into, and is often used to render scenes made in, the 3D modelling software Blender.
YafRay uses global illumination to produce realistic renderings of 3D scenes. YafRay can build photon maps for caustic reflections, and can use a skydome for quicker rendering. Recent developments include subsurface scattering shaders and increasing integration with Blender.
