Detail-preserving deformation for large-scale point set surface

A reduced graph representation,ObbGraph,for large-scale point set surface was proposed.Based on this representation,an efficient and detail-preserving method for point set deformation was also presented.The method firstly embeds the point set with an ObbGraph structure,which is based on the construction of OBBTree and the intersection algorithm of oriented box.The deformation of point set is then implemented by the linear combination of each node's affine transformation of the embedded ObbGraph.The affine transformation of the ObbGraph is obtained by a non-linear optimization.As the affine transformation of each graph node is constrained to be as rigid as possible,the detail of the original point set is properly preserved.Experimental results show that this method is fast and can effectively implement the deformation of the large scale point set with detail preservation.
