摘      要：As the key problem of content-based threedimensional model retrieval,feature extraction methods do not achieve ideal performance at *** of past feature extraction methods just utilize the attributes of the model ***,it is a promising direction to utilize the categorization information in the process of feature *** to the fact that models in the same category have many similarities and little differences,we represent the contents of models in one category by elastic *** also introduce the feature extraction and the selecting method of the optimal ***,we state an effective retrieval mechanism based on *** experimental result shows that our method performs better than the traditional ones.
