>The issue with voxels is sparseness - to have any hope of storing a world in the ram we have available it pretty much needs to have some variable length encoding, which makes it extremely difficult to use in a parallel manner as required by hardware. Signed Voxel Octrees, and SVO Directed Acyclic Graphs in particular solve this pretty well. Most megavoxel engines are an implementation of this paper: https://graphics.tudelft.nl/Publications-new/2020/CBE20/ModifyingCompressedVoxels-main.pdf https://graphics.tudelft.nl/Publications-new/2020/CBE20/Modi...
