Tesseract Fold is a kaleidoscope and geometry effect in FRCTL, the browser VJ studio. Projected 4D fold math bends the image inside out.
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.
Treats the frame as a slice of a 4D shape, folds it four times and spins it through the extra dimensions, so the picture turns inside out into mirrored lens shapes that keep rolling through each other. A rainbow wash cycles over the result. Fold sets how hard each fold bites, Twist the 4D rotation speed and angles, and Spectrum how bright and strong the wash lands.
Using Tesseract Fold
Where it works
Heavy peak-time visuals and abstract loops where the source only lends its colours and shapes. It turns any logo into rolling geometry, which suits a drop better than a cover.
With the music
The 4D rotation runs on its own clock and Speed sets its rate. Send B2 to Fold so the sub cracks the folds wider, and an LFO synced to the bar on Spectrum pumps the wash brightness.
Starting point
Fold at a quarter, Twist at centre, Spectrum at centre, Speed a little under centre, then raise Fold until the triangle starts to double.
Controls
Fold
Iteration fold offset strength.
Twist
4D rotation speed on zw/xz/yw planes.
Spectrum
Post-fold spectral color boost.
Speed
Rate of the effect motion. Centre is the authored speed, hard left a tenth of it.
