Marching cubes, Octree, and LOD seams

Colin Hill · 2011-02-13T01:37:52

I have implemented marching cubes for a large volumetric surface. The surface is contained in an octree which splits as you get closer to each cell, making a large (4096^3) area to explore. The problem is the seams between cells of different LOD. Here is a screenshot of the issue (there are also normal issues between cells of the same LOD, but I can fix that):I have searched quite a bit for a solution to this issue but I haven't found anything. Has anyone successfully implemented seamless LOD with marching cubes before?

Thank you for this! I generated my own lookup tables (for use with your paper), but I think yours will be a lot better (I still miss the lookup tables for transition cells, so...).
