Abstract. Superquadrics are able to represent a large variety of
objects with only a few parameters and a single equation. We
present a superquadric representation strategy for automotive parts
composed of 3-D triangle meshes. Our strategy consists of two ma-
jor steps of part decomposition and superquadric fitting. The origi-
nalities of this approach include the following two features. First, our
approach can represent multipart objects with superquadrics suc-
cessfully by applying part decomposition. Second, superquadrics re-
covered from our approach have the highest confidence and accu-
racy due to the 3-D watertight surfaces utilized. A novel, generic 3-D
