Lecture 9: Ray Tracing & Acceleration Structures (38)

I wonder if we can use multi-resolution voxel grids, and at the lowest resolution the step size is large. Once an occupied voxel is hit, we begin traversing from that point in a higher resolution grid.

I think I'm a little confused still about how too much grid resolution contributes to making it too slow. In lecture I think they said that you have to look up too much stuff, but I feel like since the area you have to traverse is smaller, so would it not cancel out?
