To understand how this effect works, consider the following information about the physics of waves: A wave consists of a peak and a trough. The
amplitude of a wave is the height, or distance, between the peak and trough. The wavelength is the distance from one peak to the next.
Frequency is the number of waves per second passing a fixed point.
View controls
View controls specify the method used to preview the Wave World effect. Choose one of the following views:
Displays the highest points as bright pixels and the lowest points as dark pixels. Use this view when creating a displacement map.
Provides a visual depiction of how the wave is being created. The grayscale output represents a height map: White
represents the highest possible wave, and black represents the lowest. The two rectangular outlines represent these two extremes: The cyan
rectangle represents pure white, and the violet rectangle represents pure black. The green grid represents the ground layer; it is flat by default but
can be distorted by using a grayscale image. The white grid represents the surface of the water.
Wireframe controls
Wireframe controls fine-tune the appearance of the wireframe model. These controls don’t affect the grayscale output.
Rotates the wireframe preview around the horizontal axis (right and left). As you adjust this control, the distortion of the
wireframe model keeps the entire wireframe model in full view.
Rotates the wireframe preview around the vertical axis (up and down).
Distorts the wireframe preview vertically so that you can see heights more easily. It doesn’t affect the grayscale output.
