The disclosed simplified constrain for 3D body mesh model comprises: finding the place on the model to add supporting ring constrain; to every found place, selecting three vertexes on model to determine the ring plane; searching other vertexes near the ring to determine the ring; according to relation of model edge and ring, classifying edges to calculate converted weight value and position for every edge with different methods, and simplifying with different strategies. This invention introduces low coupling, high quality, and low complexity. |
