[Bf-committers] Project an image from a point

[Alexis Piron]

Hi, I'd like to simulate a video projector accurately (that is, if something
is between the screen and the projector it makes a shadow, and the
projection comes from a point, not parallel thus).
See http://www.elysiun.com/forum/viewtopic.php?p=512791 if you're wondering
what the hell I mean...
Is this possible without resorting to raytracing ?

TIA



Alexis
