You don't need to do all of this, though. You could just do arbitrary rendering using GPU compute, and only store a highly-compressed representation on the CPU.
Yes, but then the GPU needs that amount of ram, so it's fairer to look at the sum of RAM + VRAM requirements. With compressed representations you trade CPU cycles for RAM. To save laptop battery better required copious amounts of RAM (since it's cheap).
