Abstract. Due to the increasing interest in 3D models in various appli-
cations there is a growing need to support e.g. the automatic search or
the classification in such databases. As the description of 3D objects is
not canonical it is attractive to use invariants for their representation. We
recently published a methodology to calculate invariants for continuous
