Tunnels effect

Warp Particle Vortex

Warp Particle Vortex is a tunnel and feedback effect in FRCTL, the browser VJ studio. Procedural particles pulled into a rotating center vortex.

Runs live on video, images, a camera or generated art. Stack it with any other effect, and route LFOs, envelopes or any of ten audio bands to its controls so it moves with the music.

What Warp Particle Vortex does

Twists the picture round the centre and turns it slowly, then scatters four layers of tiny rainbow sparks that circle the vortex and stream the way Direction points. A red fringe pushes outward from the middle. Twist sets both the wring and that fringe, Spark sets how bright the specks burn, and Blend sets how much replaces the source.

Using Warp Particle Vortex

Where it works: A slow intro or ambient loop where the frame should drift rather than hit. The sparks give a still image constant motion, which makes it a quick way to turn cover art into a looping Reel or pack clip.
With the music: There's no audio input, and the drift runs on the clock. Send B8 (hats) to Spark so the specks flare with the hi-hats, and B2 (sub bass) to Twist so long bass notes wind the centre tighter.
Starting point: Twist centre, Spark three-quarters, Blend centre, Direction Up, then drop Twist toward a quarter if the art has to stay readable.

Controls

Twist: Vortex twist and radial chroma offset.
Spark: Particle sparkle add strength.
Blend: Blend toward the vortex result.
Direction: Which way the particles stream through the vortex.
Speed: Rate of the effect motion. Centre is the authored speed, hard left a tenth of it.
