Platonic solids and a teapot rendered using Renderman shaders as an exercise at MFF CUNI.
To use the makefile, you'll need 3Delight. If you're not on Windows, remove the .exe suffixes from the commands. You do not need ImageMagick, the target convert is mostly there for the use of this repsitory.
During the rendering the error 'voronoi.tdl' not found is thrown twice because the texture is only ready (and actually used) in the third pass of the render. So just ignore it.
