The meridian Renderer

 

Http://www.sunfishstudio.com/index.htm

 

This is
Very interesting Renderer. It has a different approach that is very
Promising and based on Modal
Intervals
. They dont use micropolygons or point sampling.
Renderer supports high quality displacements, motionblur and Maya
Paintfx. And-Thats the best-the memory demands are really low,
Even for the largest scenes. Check it out.
