WaveInterference

◊ Brief

Each emitter throws out concentric wavefronts at a fixed wavelength. Where crests meet crests they brighten; where crests meet troughs they cancel. The cursor is a live source — click to drop a permanent emitter and watch the fringe pattern lock in.

• wavelength≈ 22 px
• angular speed5 rad/s
• fade rate0.04 /s
• max sources6

§README

1. §01Drawn as additive concentric rings rather than per-pixel sums — visually identical to a true field renderer at this density, with O(sources × rings) cost instead of O(sources × pixels).
2. §02Permanent emitters age out their amplitude exponentially, so the canvas never saturates after enough clicks.
