Products of Three Harmonics
- Cliflord A. Reiter
The Pattern Book: Fractals, Art, and Nature01 Jun 1995
Preview Abstract
Here are patterns produced by color contouring the height of functions that are the products of three harmonics; one harmonic in the x, y, and radial directions each. In particular, Fig. 1 is colored by the height of the function in the domain: −32 ≤ x ≤ 32, −24 ≤ y ≤ 24. The colors are chosen to vary through blue, light blue, light cyan, green, yellow, and white as the function height varies from −1 through 1. Figure 2 is a color contour plot for the function on the same domain with the same coloration scheme. Notice the vertical, horizontal and circular 0-level sets in both figures.
