Abstract in different language: Superquadrics are well known and often used 3D surface objects in computer graphics. They are used for modelling parts of scenes that are then rendered using photorealistic image synthesis algorithms (e.g., ray tracing). For some techniques like texturing, which are part of these rendering methods, the type of the parametrization of such a surface has to be chosen carefully and is not intuitively obvious at first sight. There are cases, where the straight forward extension of quadric parameterizations to superquadrics do not produce satisfying results. We therefore investigate a number of different parameterizations in combination with the corresponding formulas, and point out some significant differences between them.
