Resolution-adaptive mesh smoothing brush

摘要

A system and method are disclosed for implementing a resolution-adaptive mesh smoothing brush. The resolution-adaptive mesh smoothing brush computes updated positions of vertices of a 3D mesh based on vertex density of the polygons defining the 3D mesh. The resolution-adaptive mesh smoothing brush effectively controls the “rate” of smoothing based on the local mesh density at each vertex. Therefore, areas of the 3D mesh with varying vertex density are smoothed. For example, elevated bumps or dimples on a sphere may be smoothed to lay on the surface of the sphere while the sphere shape is retained.

1. A method for smoothing a three-dimensional (3D) mesh, the method comprising:
identifying a set of vertices within an area of the 3D mesh that is operated on by a resolution-adaptive mesh smoothing brush that is configured to smooth the 3D mesh based on a vertex density of a region of the 3D mesh within a brush area of the resolution-adaptive mesh smoothing brush; for each vertex in the set of vertices, computing a dynamic smoothing rate parameter based on the vertex density that is local to the vertex; and for each vertex in the set of vertices, updating a position associated with the vertex according to the dynamic smoothing rate parameter computed for the vertex.
