HANDLEBODY REPRESENTATION FOR SURFACES AND ITS APPLICATIONS TO TERRAIN MODELING
Hélio Lopes, Sinésio Pesco, G. Tavares, Marcelo Maia, Allen Xavier · International Journal of Shape Modeling · 2003
This paper presents a new representation based on the Handlebody theory. Such representation includes a topological data structure and a set of operators which performs cut and paste operations on the surface. Several applications to terrain modeling are also discussed to exemplify its use, including feature attachments to the terrain surface.
