Abstract: Mesh model processing techniques and innovations are described herein. A mesh processing method may include determining, on the basis of a positional relationship between a first vector on a first mesh model and at least one first spline, at least one target value corresponding to the first corner; determining the at least one target value corresponding to the first corner to be at least one respective target value corresponding to the second corner; determining a vertex coordinate of a second vertex on the basis of the at least one target value corresponding to the second corner; and determining a second mesh model at the second corner on the basis of the vertex coordinate of the second vertex.
