It is a rendering engine that uses advanced techniques, for example global illumination algorithms such as path tracing, photon mapping, irradiance maps and directly computed global illumination. The use of these techniques often makes it preferable to conventional renderers which are provided as standard with 3d software, and generally renders using these technique can appear more photo-realistic, as actual lighting effects are more realistically emulated.
