Abstract: For the model retrieve of largcscale threcdimensional inefficiency, this paper presented a threcdimensional model retrieval method based on the idea of incremental clustering. Firstly, for the models among the model base, constructed a retrieval words codebook. Then extracted the feature points to attain the feature vector of models according to the feature histogram,after that,followed by an incremental clustering method and update retrieval words codebook. Finally,a feature vector matching method was used to determine whether the model base contains the models which is related to the target model. Experimental results show that our implementation can get the retrieval result rapidly and precisely.
