View Full Version : Shadow Volume fillrates
08-28-2002, 01:13 PM
I have made an automatic shadow system for my scene graph using both shadow maps and shadow volumes. I am having problems with fillrate using complex models in the shadow volume version. What can I do with This. Any ideas... What do they do in doom. I guess they have the same problem...

There is a topic " Shadow volumes sooo slow... (http://www.opengl.org/discussion_boards/ubb/Forum3/HTML/006875.html) " which already has alot of info about fillrate optimization for stenciled shadow volumes.

OK. Thanx. The scissor stuff is obsolete in my code beacuse of my method can create volumes the only contains the shadow receivers and not further.
the two sided stencil setting is perhaps a good future...
perhaps some occluder can be used to deal with situations when the occluder does not need self shadowing or even split the volume into several volumes to deal with self shadow + far object shadowing. (No stencil volume in between)
