A normal vector shows the entire shape of a model well. The distribution of normal vectors was sampled in proportion to each polygon&amp;039;s area so that the information on the surface with less surface area may be less reflected on composing a feature descriptor in order to enhance retrieval performance. At the analysis result of ANMRR, the enhancement of approx. 12.434.7 compared to the existing method has also been indicated.</abstract> <index>Open Science Index 33, 2009</index> </article>
