US Patent:

6781594, Aug 24, 2004

Filed:

Aug 21, 2001

Appl. No.:

09/935123

Inventors:

Michael R. Day - Santa Monica CA

Assignee:

Sony Computer Entertainment America Inc. - Foster City CA

International Classification:

G06K 900

US Classification:

345589, 345426, 345606, 345607, 382162

Abstract:

The intensity of specularly reflected light from an illuminated object is represented by an algebraic expression including multiplication, addition, and subtraction operations. The algebraic expression is used in an illumination model, where the illumination model describes the color and intensity of light reflected by the illuminated object. Light reflected by the illuminated object is composed of ambient, diffuse, and specular components. The specular terms used in the illumination model are equivalent in functional form to the diffuse terms, thereby accelerating the computation of color vector c defined by the illumination model. A modified algebraic expression representing specularly reflected light from an illuminated object is defined and used in the illumination model, thereby accelerating computation of color vector c.
