Is it possible to simulate a projected image using photons and radiosity?
My basic scene setup is as follows:
C = Cylinder (Object (ideally) projected)
L = Lens (A curved peice of glass)
B = White box ('Screen')
P = Light Source
PP
PP
CC BB
CC LL BB
CC LL BB
CC LL BB
So far, no luck.
Scene source follows.
