POV-Ray computes radiation transfer via monte-carlo integration.  Since 
it handles a lot of arbitrarily complicated geometries it should be 
obvious that it does not calculate form factors analytically.  AFAIK all 
  rendering programs that use form factor based methods rely on FEM 
based techniques and compute transfer between simple surface (or volume) 
elements.
