IMHO,
	POV-Ray is a complete general raytracing algorythm...  which will be fast for
almost anything...

	My scene has no light, nothing else than a few millions of cylinders all the
same texture...  how can I optimize that for povray? Reduce the number of
cylinders? Wrong!  That would also reduce the realism of my scene... what I need
is a raytracer that would handle very easily and very fast such a big number of
"Cylinder" and would be simply very slow when you would only have a cube... 
Optimized for a large number of cylinders, that is what I need!  Also that I got
a C++ program that calculate the position for all these cylinders and outputs
the result in a povray script...  ( cylinder { <x,y,z> texture { TheTex }})  and
then povray starts Parsing the scene and takes forever...  Would take a double
forever if I added lighting!...

	I am very interested in Povray, but sometimes I would need a specific tool...

Thanks,
	Simon
