OGL optimization.

Recommended Posts

I''m currently trying to optimize the engine I''ve been programming for a while and I need help... I''ve implented a frustum clipping algorithm that cuts a big bunch of useless data but don''t prevent overdraw wich can cause sluggish performance while rendering big and complex 3D worlds. Does anyone know a good technique to do visible surface determination? I''ve heard Quake use span sorting but it seems that I can''t find any tutorials explaining it. Thanks.

This explains in great detail how the span buffer works.

PS: Don''t ask me any questions about it. I don''t know sh*t about the sbuffer.
