Abstract
A 3D voxel grid of an environment is generated, with a signed value assigned to each voxel representative of that voxel's distance from a nearest surface. For each subset of the 3D voxel grid comprising a surface, an initial surface mesh is generated. As new depth information is received, an updated surface is generated only for those subsets of the 3D voxel grid that exhibit greater than threshold change in signed values over time.
