Laser Chase
Sweeps a brightness window across your lasers in sequence, so one (or a few) light up at a time while the rest go dark. The classic chase effect for multi-laser shows: spotlights that travel from projector to projector.
Inputs
| Port | Type | Default | Range | Description |
|---|---|---|---|---|
| Frame | Frame | — | — | The frame to apply the chase to |
| Phase | Scalar | 0.0 | 0–1 | Position of the brightness window in the sequence |
| Width | Scalar | 1.0 | 0–16 | How many lasers are lit at once |
| Fade | Scalar | 0.0 | 0–1 | Softness of the brightness falloff at the window edges |
Outputs
| Port | Type | Description |
|---|---|---|
| Frame | Frame | Input frame with chase brightness applied |
| Brightness | Scalar | Current chase brightness for this laser (0–1) |
Ideas
- Animate Phase with a Phasor for a smooth sequential reveal across your laser setup. Switch the Phasor to BPM to lock the chase to the tempo.
- Combine Width and Fade for smooth spotlight transitions; a narrow width with high fade creates a soft traveling glow.
Tips
- The Brightness output is useful for secondary effects. Wire it into color or scale to make lasers respond beyond just brightness.
- Phase, Width, and Fade are sampled once per frame (not per point).
- With a single laser, the chase has no visible effect. It's designed for multi-laser output groups.
