#ActualShadowMan777

Posted 16 February 2013 - 02:27 PM

Thanks for the responses everyone. My goal is to make a planet eventually, so I thought octrees would work out the best, so one could go inside the planet as well. from a  distance, only very large voxels would be generated for the upper levels of the octree, but then as you got to the surface, you would eventually display 1 meter cubes. So what I am trying to say is I do NOT need to generate all of it at once. I thought I might be able to procedurally produce the detail ONLY when more detail is needed for a given depth in a given node of an octree.

Thanks for that. This makes perfect sense. So each node in the octree could be a 16x16x16 grid of voxels, correct?

For rendering, I was thinking of raycasting on the GPU into a sparse voxel octree. If I was at the surface, lets say, I would only be rendering as many cubes as you might see in a minecraft scene. And if I looked 100 miles to the east, I might see a mountain range rendered with very large cubes(as it is very far away). This is what I am going for.
