A NEW APPROACH TO THE TRIANGULATION SURFACE RECONSTRUCTION FOR SLICING CONTOURS

摘要：

Aiming at the multi-nesting and multi-branched complicated slicing measurement data, a new approach to reconstruct 3D surfaces with triangular facets is proposed,by which the complex cross sectional contours are firstly reorganized into a group of segments and end-faces and then each segment are subdivided into a series of surfaces (it is called as RS-DS method ).Methods to determine the hierarchical relation of planar contours and the corresponding relation matching and topology coding between adjacent layers are introduced.The algorithm is also designed for complicated slicing contours by RS-DS.In RS-DS, the least polar-angle criterion is used for linking two adjacent slices with triangular facets and the updated Delaunay algorithm is adopt to the end-face triangulation.In the end,some typical examples have verified the validity and feasibility of RS-DS method.
