Fremgangsmåte, system og dataprogram for fremstilling av en beskrivelse av et ikke-regul¶rt nett og en innkapslet geometriskbeskrivelse i et datagrafikksystem

摘要

The present invention relates to a method for creating an irregular mesh description and an embedded geometric description in a computer graphics system. The method comprises steps of receiving topological input data representing vertices and faces of the mesh, creating a G-map representation of the topology of said mesh based on said input data, associating coordinates in space with the vertices of said mesh, and creating a smooth geometric description from said mesh and said coordinates. The invention also includes a computer system capable of performing the method, as well as computer program product that, when installed on a computer system, enables such a system to perform the invention.
