hello!

i am thinking about generating a synthetic ground-truth benchmark image for a 3d
scanner using povray. therefore i would like to know if and how it is possible
to simulate a video projector in povray.

it should be possible to simulate each projector pixel using a spotlight and
place a lens in front of the array, but that would be extremely tedious and
probably inaccurate.

is there a way to project a bitmap onto a scene, ideally with finite
depth-of-field? after all, a projector is just a reverse camera ...

thank you
