System and method for rendering a texture map utilizing an illumination modulation value |
摘要 |
In one embodiment, the present invention is directed to a system for rendering a pixel of a digital image. The system may comprise a texture map data structure representing a texture map of a plurality of texels; the texture map structure comprising a plurality of coefficients for each texel of the texture map; the plurality of coefficients defining lighting characteristics of the respective texel in response to illumination in a plane. The system may further comprise a modulation data structure; the modulation data structure defining a range of values associated with an illumination vector. Additionally, the system may comprise a rendering algorithm; the rendering algorithm operable to calculate a texel display value using the texture map data structure; the rendering algorithm operable to determine an illumination modulation value from the modulation data structure; and the rendering algorithm being operable to multiply the texel display value by the illumination modulation value to render a pixel.
