Abstract
A method of generating an iso-surface mesh for a three-dimensional (3D) model is provided. In the method a plurality of voxels is generated in a bounding box of an input mesh, where a size of each of the plurality of voxels is based on a size of the bounding box of the input mesh and an iso-value. One or more iso-surfaces in each of the plurality of voxels are determined based on an unsigned distance function and the iso-value. One or more feature points in each of the plurality of voxels are determined based on the one or more iso-surfaces in the respective voxel and a constraint function. A feature mesh is generated based on the determined one or more feature points, and an edge flip operation is performed on each of a plurality of edges of the feature mesh to generate the iso-surface mesh.
