Hi ,
I'm doing some 3d graphics routines,
And I've some tuts and docs about Z-buffer
but it all seems that they only work or are intended for
ORTOGONAL proyection, not perspective. (they just cut the Z coord.)
Are there some understandable tuts or docs, even C implementations
of a REal Z-Buffer algorithm, for perspective proyection.
Hey man I need them. 

Thanks
