I have been reading about sparse voxel octrees, and I was interesting in using one to render a large surface, where each point in space is 1 meter. If I wanted to render a surface that was, lets say, 100 miles across, I would have to have to have an octree that could represent 160934 units across(which would be 18 levels deep in the octree If I am not mistaken). Is this feasible? I would be procedurally generating the data in the octree as it was needed(as the camera gets closer to the surface). Thank you for any input or guidance.
