WebEdit: So, I've worked this out a bit, and would appreciate if somebody could verify that this would be the proper way to triple buffer my lights SSBO. Assume we split it into three buffers: A, B, and C. Display A, while drawing into B. In my case, I guess "drawing" would actually mean writing my updated light positions into the buffer. WebDescription This sample demonstrates how to use extensions to OpenGL to offload the CPU in generating rendering work when you have a large number of objects in a scene. The extensions and core features used are a subset of the features commonly known as 'AZDO' (For Approaching Zero Driver Overhead). APIs Used GL_ARB_multi_draw_indirect
