I think it's a little more complex than that. In addition to rasterizing a large number of pixels, the entire vertex pipeline has to run 45 times to generate 45 projections of the scene's geometry. You're correct though in that the rest of what happens in a frame (physics, animations & other state updates) do not have to run 45x.
- gmueckl 8y agoThis is an application where ray tracing for primary rays should shine. Instead of having to project thw scene 45 times you only need 45 sets of ray bundles, which is really efficient. The acceleration stuctures are shared between views. With a few pixel reordering hacks you can essentially generate all viewpoints as a single high resolution frame.
- pasta 8y agoThis is exactly what I was thinking about. With raytracing you will almost get this for free.
