OK. I searched almost a day around the net. 🙂 Im gonna ask the questions on the gamedev forum, but what does that mean “How can we apply visibility tests?”
While i searched, i found this ->
http://www.geeks3d.com/glslhacker/cs/ – looks very nice, like eye candy images!
http://rastergrid.com/blog/ – Looks like very nice site. It have some nice stuff, like GPU based dynamic geometry LOD, Hierarchical-Z map based occlusion culling…
Hope those links are useful.
