Hi,
I would like to have car headlights in my driving simulator, so I use
the TexGen class (with EYE_LINEAR) to do that. Like in the spotlight
example, I have a nice spotlight, but with one artefact, which comes
from the fact that the matrix math used produces a BACK PROJECTION.
I've read that this artifact has historically been avoided by using a
special black and white texture 1D to cut away unnecessary projecting
contributions... but how to do that in OSG ? Have someone experimented
this way ?
Thanks in advance,
Josselin.
