Waveform Tunnel
A spiral with a fixed wave term layered into the radius, producing a ridged, tunnel-like path that recedes toward the center. Useful for vortex shots, hyperspace looks, and any scene that wants depth without a real 3D camera.
Inputs
| Port | Type | Default | Range | Description |
|---|---|---|---|---|
| Size | Scalar | 0.5 | 0–1 | Overall scale |
| Turns | Scalar | 4.0 | 0–64 | Number of revolutions from outer edge to center. Values below 1 behave like 1 |
| Exponent | Scalar | 1.0 | 0.25–2 | Wave depth: low values flatten the ridges, high values exaggerate them |
Outputs
| Port | Type | Description |
|---|---|---|
| Frame | Frame | Open spiral path with wave displacement |
Ideas
- Drive Turns with a slow Phasor to pull the viewer through the tunnel.
- Animate Exponent with an Oscillator for a breathing tunnel that pulses with the music.
- Feed into Camera Projection with Pan/Tilt animated by Noise for a handheld, drifting look.
Tips
- The wave cycles and phase are fixed inside the node, on purpose. To animate the look, drive Turns and Exponent, or animate a node downstream such as Camera Projection.
- High turn counts create dense paths that cost scanner time.
