About Vortex Tunnel

Vortex Tunnel propels you through an infinite spiraling tunnel where the walls twist, pulse, and glow in response to your audio. The forward motion never stops -- you are perpetually accelerating through a kaleidoscopic corridor of light and geometry, with the tunnel's shape, color, and rotation speed all driven by the music. Bass deepens the tunnel and increases forward velocity while treble adds fine geometric detail to the walls. The tunnel geometry morphs continuously. During verse sections, it might be a smooth, gently rotating cylinder. When the chorus hits, it transforms into a jagged, rapidly spinning polygon. Drops cause the tunnel to constrict dramatically before exploding open. Every structural change is synchronized to the beat grid, creating a narrative of spatial transformation that mirrors the musical structure. Vortex Tunnel is the ultimate speed effect. The relentless forward motion combined with the spiraling geometry creates an adrenaline-pumping visual experience that matches the intensity of fast-paced electronic music. It is a go-to effect for DJs, streamers, and anyone who wants their visuals to feel like a high-speed chase through another dimension.

How it works

The tunnel is rendered using a ray-marching fragment shader. The signed distance function for the tunnel is a deformed cylinder with audio-reactive radius modulation, cross-section polygon count, and twist rate. Forward motion is achieved by translating the ray origin along the tunnel axis at a speed driven by RMS energy. Wall patterns use repeating UV coordinates with audio-reactive procedural textures. The twist rate is quantized to the beat grid for rhythmically coherent rotation. Post-processing adds motion blur along the forward axis to enhance the sense of speed.

Science Behind This Effect

Vortex Tunnel's rotation speed maps to the arousal dimension of tempo-emotion research — faster tempos create faster tunnel rotation.

Frequently Asked Questions

Does the speed change with the music?+
Yes. Forward velocity is directly mapped to the overall audio energy. Loud, energetic sections accelerate the motion while quiet sections slow it down, creating dynamic speed variation.
Can I change the tunnel shape?+
The tunnel cross-section can be set to circle, triangle, square, hexagon, or star shapes. You can also enable audio-reactive morphing that transitions between shapes on beat.
Is there a risk of motion sickness?+
The constant forward motion and rotation can cause discomfort for some viewers. You can reduce the rotation speed and forward velocity in settings, or add a center reticle to provide a stable visual anchor.
