Abstract

A method of generating a global three-dimensional representation of a color space. Initially, the color elements associated with a color space are quantized. A three-dimensional color space frame model is generated based upon the color space. The quantized color elements are mapped to the three-dimensional color space frame model. Accordingly, perspective parameters are used to manipulate the three-dimensional color space frame model to provide different three-dimensional views of the three-dimensional color space frame model.
