Thyandyr's voxel engine

Why keeping all this in single vbo?
btw occlusion culling will be possible with this approach?

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.
