A Direct Slicing Algorithm Based on the Point Clouds Data
Zhao Ping · Transactions of Shenyang Ligong University · 2009
In the foundation of geometry topology relation between points each other and being many redundancy data often exist two great difficulties in the process of reconstruction of scattered data.In order to realize precise compression of scattered data and simplify the establishing process of point-point geometry topology relation,the line-surface intersection algorithm based on a pair of the least distance relative points and the eight-direction contour tracing algorithm of the cross-section data are used to dispose the scattered data by means of direct slicing,and the example proves that the method is effective.
