Abstract :
A unified surface smoothing scheme is proposed to fit grid points, scatter points and boundary points, which are digitized from physical models with the Coordinate Measurement Machine, to smoothness parameter surfaces. A variety of curves and surfaces with different smoothness can be obtained with the aid of parameters such as approximation and smoothness weights, segment or patch numbers and the distribution of approximation and smoothness weights. A pickup car body is finished with the proposed method
