I’m going to code a KDTree system with a dynamic occlusion system using the extension nv_occlusion_query. I mean, using a frustum culling, I will only render sectors from KDTree in the frustum, and when render a sector I check via the nvidia extension if the bounding box of the sector is visible on screen, if so I’ll render the sector else no rendering. Do you think that is worthing? I probably have many sectors (about hundreds), I know this is depending mostly on the scenary, but it’ll be mostly indoor scene. Did someone code something like that? How great is it working then?
