Hi Egon, sry having to bring this up again. I checked from forum and many people are saying that transparent object are the most expensive process for fillrate, but I don't quite sure how transparent object would affect the fillrate, in technical speaking. Hope I can hear more about it from you.
From what i can understand, the more transparent part fills up the screen, the more hardware cost it would be. Is it caused by the z buffer where it checks the z buffer and rewrite again, or something else?
Say, if I put a all transparent objects at background (they takes almost more than half of the screen), and leave the opaque 3D objects at front, does it help in fillrate?
