Didn't know that. Thanks. (BTW, I'm no 3d expert, my background comes 
from Signal and Image Processing).

May be you're right, but as I'm only rendering 2d objects, the 
computational cost should be much lower than for ray tracing. Besides, 
if Morphic 3 turns to be usable only with help from OpenCL or CUDA or 
some other special hardware, it is not too bad.

Thanks for your comments!
