Hi all,
I'm looking for articles, papers, tutorials or other online detailed information about z-compression theory and implementation.
Recently I got interested (again) in hidden surface removal and occlusion culling. So I'd like to understand more about how it's implemented by modern software (not necessarily for real-time rendering) and hardware. I found lots of information about hierarchical z-buffers and many variants of occlusion maps but not z-compression and/or it's interaction with existing techniques. Knowing the details could help a lot to efficiently render complex scenes.
So if you know any resources or would like to share some knowledge, please inform me. Other ideas about improving z-buffer performance is welcome as well. Thanks!
Nick
