In order to obtain slicing data for scattered points rapidly and accurately,and to express the information of model with less data,an acquisition and optimization algorithm for slicing data was proposed.The slicing data was obtained based on the dynamic special index structure of scattered points,and the slicing data was divided into many sector zones based on the polar angle threshold.The contour was separated by the distance threshold,and the slicing data was reduced and sorted by connecting the zones' cores.Precise and orderly single-contour and multi-contour slicing data was generated.The results show that the algorithm can obtain the slicing data of various complex scattered points accurately and effectively and has important significance for improving the efficiency and precision of parameter curves and surface reconstruction.
