Three dimensional modeling and animation system

摘要

A three dimensional (3D) modeling system for generating a 3D representation of a modeled object on a display device of a computer system. The modeled object is represented by an initial definition of an object and a set of modifiers. Each modifier modifies some portion of the definition of an object that may result in a change in appearance of the object when rendered. The modifiers are ordered so that the first modifier modifies some portion of the initial definition of the object and produces a modified definition. The next modifier modifies the results of the previous modifier. The results of the last modifier are then used in rendering processes to generate the 3D representation.
