Phase

Phase introduces turbulence into your noise. The phase displaces the grain or patterns within the noise. When you design the phase, you're creating a displacement map along which the noise will be modified.

You can control how the phase interacts with your noise using the Phase palette. You can design your phase using the Phase Editor. The Phase palette controls the amplitude. The Phase Amplitude controls the intensity of the displacement. As the amplitude is increased, there is more interference with the original noise.

You won't have to increase the amplitude very much before you start seeing the phase pattern you designed interfere with the existing noise. In fact, it's probably a good idea to keep the phase amplitude low so that the phase pattern doesn't overwhelm the noise.

This graph shows how the phase interacts with the noise at different amplitude settings.

The Phase Editor looks a lot like the Noise Editor. It has the same type of tools and they work exactly like they do in the Noise Editor. The difference is that you're using noise patterns, orientations, frequencies, and modes to design how the basic Noise will be displaced. Using the Phase Editor you can perform several functions:

• Create 1D, 2D, or 3D phase.
• Change the type of noise.
• Change the frequency of the phase.
• Change the orientation of the phase.
• Change the noise octaves.
• Change the noise modulations.

While the Phase Editor lets you create the noise pattern or grain within the phase, the Phase palette controls how that phase is applied to the component or the combined texture.
