METHOD FOR COMPACT REPRESENTATION OF CONNECTIVITY OF A GEOMETRICAL MODEL

摘要

The invention concerns a method for representing the connectivity of a geometrical model initially in the form of a mesh, the representation being performed by means of a generalized card consisting of a series of strands (1, 2, ..., 16) and of a series of connectivity relationships (a0, a1, a2), characterized in that it comprises a step which consists in establishing a compact representation of the connectivity in the form of a history of neighbourhood path for each individual strand of the generalized card.
