Texturing method of the full pixel dynamic range

Texture is perhaps the most important attributes of a face. Textures are patterns derived from full-color photographs, drawn by an artist, or synthesized by a computer. When applied to the face, texture adds a lot of detail and realism. Without the motion and distance cues provided by texture, low-level flight training in simulators would be almost impossible.
Shading, the intensity of the light reflecting off the surface of an object, gives the viewer important perceptual clues to the object’s shape. The amount of light reflected from a surface depends largely on the slope of the surface with respect to the sun or other light source.
The paper highlights lights in a volume-oriented rendering which features a lot of advanced techniques intended to synthesize a highly realistic visual environment for a diverse set of applications.
According to proposed method there is almost no need to go higher than 12 bits if the illumination models is computed at a higher resolution because it is then possible to distribute a particular texture over a restricted range of the full pixel dynamic range.
