  • Tinting a surface to simulate a visual effect in a computer generated scene
    Patent number: 8310483
    Abstract: A tinted color value is produced for a surface of an object in a computer generated scene. The surface is illuminated by a light source having a lighting color value associated with the light source. A first reflected color value is calculated for the surface. The first reflected color value is calculated based on an assumption that the surface is illuminated by white light rather than the lighting color value associated with the light source. A desaturated color value is computed using the first reflected color value. A tinted color value is computed by combining the desaturated color value with the lighting color value associated with the light source. The tinted color value is stored.
