English: A 3D rendered image using ray tracing, radiosity and photon mapping, rendered by the POV-Ray program.

The smoothness of the meshes used for the cows has been increased using subdivision. The scene uses very simple lighting, and uniform background colors, to make it easier to interpret differences in global illumination.

Radiosity was used to simulate indirect illumination, and photon mapping was used for caustics. The area under the cows is now realistically lit, and the glass cow has a shadow. The caustics are much more detailed and realistic-looking than the ones rendered by path tracing in Blender's Cycles renderer. It took almost three minutes to render (no GPU acceleration used).
