Well, I have been reading about the scissor optimization technique (Mr.Lengyels article in gamasutra and Mr.Everitt’s demo on nvidia). I just cant figure out whats happening. If someone could point me to a more detailed explanation on this topic I would be grateful.
I realize that the lights’ boundaries have to be found to cap the shadow within this volume so as to avoid unwanted fill. but how exactly are you guys doing it, somehow all of it does not make a connection in my head. Could someone please explain?
