For retrieving similar models more efficiently from 3D model database,this paper proposed a slice-cutting based 3D model retrieval method.Firstly,used PCA to preprocess a 3D model.Then,cut the preprocessed 3D model into slices using planes normal to principal directions.Finally,selected the ratio among the areas of these cutting slices as the representation of a 3D model and used to calculate the similarity between models.It developed a retrieval system based on this algorithm.The experiment adopted PSB 3D model database for retrieving.The results indicate that cutting slices based 3D model retrieval method is effective and promising.
