Gradient Parameters A cylinder is shown grading from black (top) to
white (bottom).

When you create a 3D map, notice that the Coordinates rollout has Tiling and Offset
parameters in three axes, whereas the 2D maps only have X and Y.
Try using some of the 3D maps (such as Marble, Wave, Stucco, and Wood) to see how
they work on a simple object in your scene. They all have basically the same Coordinates
rollout; however, each has its own Parameters rollout to control the color and other settings.
Marble
A Marble map creates veins of colors that run through an object. The 3D aspect of the
map allows it to spread across all three dimensions, creating a more realistic texture.
Color #1 and Color #2 control the two colors of a Marble map, while the third color is a
grainy blend of the two together, shown in Figure 7.55.
The Marble Map Parameters The Marble map??™s parameters are shown here
applied to a cube.

Here??™s what happens when it is applied to a cube.

Noise
Noise is a great way to easily add some randomness to a parameter or to add a bit of randomness
to a surface??™s color or specular highlight, for example.
