We build a method for new feature descriptions of 3D models. This method is based on independent or combined descriptors with shape and specular reflection to retrieve 3D models with light. Light plays an important role in form and appearance of 3D objects. We obtain a good relationship between shape and specular reflection and high-grade of 3D chair models. We compare independent descriptors and combined descriptors for shape and specular reflection by multiple regression analysis. As a result, we find that form and the position of specular reflection play an important role in high-grade response to 3D chair models using two kinds of light.
