An inversion algorithm for geometric models

Instead of storing boundary models of solids directly into a data base, it would be advantageous to map them first into a simpler form. This approach calls for a procedure called in this paper the inversion algorithm of a geometric model. We present and analyze an inversion algorithm which constructs a sequence of Euler Operators capable of creating a given boundary representation. The algorithm is completely based on the use of Euler Operators enabling us to keep the algorithm simple and to hide implementation and data structure details.
