Abstract

We describe an algorithm to generate a manifold mesh from an octree while preserving surface features. The algorithm requires samples of a surface (coordinates) on the octree edges, along with the surface normals at those coordinates. The distinct features of the algorithm are:
- the output mesh is manifold,
- the resolution of the output mesh can be adjusted over the space with octree subdivision, and
- surface features are generally preserved.
A mesh generation algorithm with this combination of advantages has not been presented before.
