Tunnel

Looping depth corridors, tubes, fields, and camera paths with deterministic fog.

Launch modes

Concentric Rings mode

Concentric Rings

Evenly spaced ring segments move through a looping depth field.

Corridor Grid mode

Corridor Grid

Walls and floor form a measured perspective corridor.

Warp Field mode

Warp Field

A point field accelerates visually while velocity stays bounded.

Spectrum Tube mode

Spectrum Tube

FFT bins deform a tube surface through bounded envelopes.

Waveform Tube mode

Waveform Tube

Time-domain samples travel along the tunnel cross-section.

Particle Vortex mode

Particle Vortex

Particles spiral through a shared camera-space vortex.
