Wave patterns: Bulge

Draw rows of waves from the curves of trigonometry and signal processing, in lines or filled bands. Every repeat holds whole waves, so its edges always meet.

Bulge

Wave

Lines swell apart around each lens and crowd together between them, an op-art bulge. The lenses sit in a square grid, the same number down as across; more lines show the curve better.

Second wave

The second wave is added to the first, point by point, for a wave riding on a wave.

Colors

Lines and bands alternate the line and accent colors. Filled bands are outlined in the background color.
