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, andsurface features are generally preserved.A mesh generation algorithm with this combination of advantages has not been presented before.
