Hi all, Thanks to TheGoop, I''ve implemented some good translucency stuff in my program-- only I have a bit of a problem. This problem is not with DirectX or anything but logic, and I am merely querying to see if anyone has had the problem before, and has a good solution for it. When I draw my translucent 3d objects, I get some overlap on the draw. The upshoot of this is that if I draw a ''behind'' polygon first (translucently) and then draw the ''in front'' polygon, I''ll be able to see the behind polygon through the translucency. So, instead of having a one-level translucent creation, I end up being able to see what is very obviously a 3d object, and it doesn''t look too good. I played around with the sorting, and found that as long as I drew the triangles front to back, they clip like I want them to. I.E. the translucency behaves just like anything else with the Z buffer. SO-- I''m asking if anyone has any superfast method of sorting a series of triangles to determine who is foremost, or if, even better, direct3d has a method like that itself. I want to make sure my triangles are drawn front to back, but the implementation needs to be VERY FAST, as it would rest in the main game loop. Any idears?
