Sprite Clipping discussion

[RaVeN]

Source code for Strife Veteran exist, and it have great sprite positioning algorithm that exactly the same as in software rendered doom engine but in OpenGL
Good idea to see it here too

I said several times already, that this algorithm depends on severe geometry limitations. It can't be made to work with 3D floors and a few other constructs because it works by screwing with the depth buffer. You cannot do that if you still need it.
