ABSTRACT

Modeling of 3-D objects and surfaces is the prerequisite of many applications in computer graphics and computer vision. It should follow a scientific or mathematical representation that conforms to optimal storage and efficient computation. Modeling is primarily done in two broad categories: one for regular geometric objects (polyhedra, platonic solids, etc.) or well-defined mathematical surfaces, and another for real-world objects (sculptures, day-today objects, living organisms, etc.). See Fig. 7.1 for some typical examples of 3-D models with triangulated surfaces.
