The result is extremely similar to the first image, but is the precise logical opposite. This kind of thinking is typical of all areas of 3-D graphics, in part because the various tools have come together from so many different directions and have been collected into packages, often without regard to overlap and inconsistency. In the current infancy of 3-D, this is to be expected, and has some advantages because there is so much to explore. But the new 3-D artist must learn to be creative with tools and to always be alert to new possibilities that were not necessarily anticipated by the developer. To make the point further, here's yet another approach to creating the same effect.
Some applications provide a direct control over the degree of diffuse color response.
This is effectively the same thing as removing light from the surface of a specific object without reducing the intensity of the light itself. This is just one more thing that is possible in 3-D that is impossible in the real world. Just as we have used luminosity to brighten shaded areas without changing the lighting, we can use the diffusion control to darken areas as if they were shaded. I have changed the underlying diffuse colors here for a little variety. Arrow Buttons Copyright 2001 INT Media Group, Incorporated All Rights Reserved.
