Texture mapping is the
method by which the models are painted. All texture maps are created in a digital paint
program. Traditional and modern painting techniques are utilized to create the various
layers that make up the characteristics of a models surface. While there are additional
maps ( for reflectivity, transparency and specularity ) the three basic maps shown below
illustrate the importance of texture design and application. Each map is a painting unto
itself and may require hours of attention to insure the model will look correct. |

BUMP MAPS: Are gray tone images that the computer will translate
according to tone value. Bright shades read as extrusions on the surface while dark tones
will read as depressions. Bump maps are good for subtle details like panel lines and
rivets |

DIFFUSION MAPS: Are also gray tone images that effect how light will react
to the model's surface. Depending on values, the surface will appear dull and dirty
or bright and clean. Works well for illustrating grease grime and worn paint. |

COLOR MAPS: Are full color images that are applied to the model's
surface. Any markings or graphics are incorporated into the color map. The completed model
on the left wears a total of 131 texture maps. |
