I have a simple question and i wanna know the views of people-"How does a 3d rendering engine compute the infinite processing power required to render two reflective surfaces which are placed in front of each other??"I posted this in chit-chat but i didn't get many replies so I m here as It's related to software..I think companies like nvidia and ati should show their graphical computational power with the help of the demo in which many reflective surfaces reflecting each other are rendered.
