POV-Ray is a ray-tracer.  It does not tessellate objects in order to render
them.  In general it is no help for your problem.

You will need some software to get you polygons as scene information.  You
can then turn those polygons into triangles and apply the heat transfer
equations.  The same math is actually used in the classical radiosity
computation, so you may also want to look for implementations of classical
radiosity.
