Large numbers of 3D model have been used in the product design and 3D artifact,but problems have occurred that attribute data is incomplete;the search method is inaccurate based on attributes.Consequently,the search engines can not provide effective search service.This paper proposes an area distributions based method.According to this method,summarize the total area and average area of the vertex of the 3D model,normalize the list of the area distributions list and Fourier transform the list;get the final ...
