Object Modeling: Topology and Symmetries

In 3D imaging and modeling, several applications require the definition of conceptual models, which imply the knowledge of the 3D topology. Working in 3D, as well known, is much more complex than in 2D. The combined study of topologic and geometric relations between primary elements and symmetries in the spaces in which the complex objects are located, allows noticing some analogies between the number of the found relations and the number of groups of symmetries.
