In order to improve the efficiency of the content-based 3D model retrieval,a 3D model-retrieval approach by gene matching is proposed.The genome of 3D model is represented by geometry API as construction gene and topology API as coordination gene in CAD.The similarity between genomes implies the number of equal gene blocks and the average similarity of all construction genes.A gene block is a sequence of gene codes with the same sort,which corresponds with the shape feature and is identified by the algorithm of string pattern matching.Construction gene similarity is the linear function of the Eulid distance between two genes,which is calculated by gene ergodicity.The similarity of the evaluated genome is calculated according to the target genome,the examples test demonstrates the effectiveness of the retrieval method.
