Bloomback applied to FRCTL's test image: Filaments swell out of the frame and travel, growing new ones behind them as the picture feeds the bloom.

Geometry effect

Bloomback

Filaments swell out of the frame and travel, growing new ones behind them as the picture feeds the bloom.

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.

Controls

Grow
Whether the held frame swells or shrinks each pass. Centre holds still, either side sends the filaments travelling.
Spin
Turn per pass, which curls the breeding rings into spirals instead of even shells.
Sustain
How much of the held frame survives each round. Past centre the nest stops decaying and keeps thickening.
Bands
Contour rings across the accumulated bloom. Low is a few travelling shells, high is a dense nest.
Tint
Rotates the whole rainbow around the wheel.
Cycle
Hue step per ring. Low spreads one rainbow over many rings, high gives every ring its own colour.
Glow
Light falling off the strokes. Hard left is a bare filament, up high each one blooms into the frame around it.
Speed
Rate of the effect motion. Centre is the authored speed, hard left a tenth of it.
