Does anybody know when exactly the shadow map projected onto the scene by
Performer to cast shadows is computed?? in the APP, CULL or DRAW? I think
it's just before the DRAW isn't it?
Has anybody had success reading the shadow map?
I mean, is it possible to read the shadow map content in memory? and
eventually save the content as a texture file? ( something like
pfTexture::saveFile(char *fname) )
Or how can I read the z-buffer of a scene generated from the light source
viewpoint and create a texture with the z-buffer content?
The point of doing that is that I want more resolution for my texture than
what Performer is giving (using a 512x512 shadow map) so I want to try to
process the shadow map maybe to render a scene with possibly non-realtime
realistic results.
Is somebody generating shadows in Performer with another technique than
shadow maps?
Thank you.
Jorge
