Acoustic Lens casts rays from a central origin and refracts them through elliptical lens shapes using a Snell's law approximation. Audio frequency bands control the refractive index of each lens, bending rays differently across the frequency spectrum. Beats shift the lens position and briefly increase all refractive indices for a dramatic bending effect. Six modes alter the lens arrangement and ray spread.
Key Features
Parameters
| Parameter | Description | Range / Options |
|---|---|---|
| Lens Mode | lens / prism / mirror / diffuse / scatter / waveguide | Select |
| Ray Count | Number of rays cast per frame | 16–128 |
| Refractive Index | Base bending strength of the lens | 1.0–3.0 |
Tips & Best Practices
- 1
Prism mode separates rays into a spectrum fan — striking with high Ray Count.
- 2
Mirror mode bounces rays back — creates X patterns that pulse with bass.
- 3
Waveguide channels rays into parallel paths that split on beats.
Export Performance
2D Canvas engine. Ray Count scales rendering cost — 64 is the sweet spot. 128 rays is visually dense but CPU-heavier.
