I'm learning by doing and just wanted to see what happens and how much can push to one VBO. I will only remember things that I learn if I have first hand experience of the 'why' of things. Seeing something work or fail is essential to me.
Sure occlusion calculations will be possible, currently I only draw voxel surfaces that have solid-gas interface (assuming atmosphere... should be called transparent-opaque interface I guess. Actually you draw glass and water too, so should be called change-of-light-refraction interface heh heh), plus chunk edges. Occlusion on larger scale will be necessary once I manage to draw more stuff on screen. I have camera and chunk locations (and voxels' too). I don't know how it's normally done but I thought do to the large scale occlusion per-chunk and not per voxel.
