Hi, I am kinda confused by the difference of depth test in OGL & Z-Buffering. Enabling the depth test in OGL will avoid drawing hidden polygons. So does this mean I don''t need to implement a polygon sorting algorithm if I have enabled the depth test? thanx Oscar

Depth test == z-buffer as far as I know (the z-buffer is the area in memory that enables the technique of depth-testing).
