If it is not there create it, otherwise use the index. Now the first trick is to realize, that for every x,y,z you only need 3 possible vertices: down x, down y, down z. green dot sight for shotgunWebb7.1 Chapter Objectives In this chapter, we introduce a simple computer graphics algorithm called marching cubes.

The total number of unique edges in each dim is equal to size+1 because the two end voxels don't share their edges. So if you had nx*ny*nz voxels, you would have (nx+1)* (ny+1)* (nz+1) edges. This can be pre-allocated as an array. fltis lab
