A method of generating a mesh includes locating a reference voxel. The reference voxel is inside a surface of an object and is adjacent to at least one voxel outside the surface. The method also includes, for a voxel outside the surface adjacent to the reference voxel, determining a set of contributing voxels by finding adjacent voxels on the same surface as the reference voxel using morph operators. The method further includes forming triangles with adjacent contributing voxels and the reference voxel. Each triangle has unique directional edges with respect to the other triangles.
