Geometry effect

Prism Shatter

Prism Shatter is a kaleidoscope and geometry effect in FRCTL, the browser VJ studio. Triangular glass shards with fractured RGB offsets.

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 Prism Shatter does

Breaks the picture into a grid of glass cells, splits each on the diagonal into two triangles, and knocks every shard a random distance from its centre. Red and blue slip apart across each shard and a thin glow runs along the cracks. Shards sets grid density, Fracture how far pieces jump, Prism the colour split and edge glow, and Shape swaps triangles for squares.

Using Prism Shatter

Where it works
Cover art and posters where the subject should look seen through broken glass but keep its outline. The break pattern is fixed, so a still stays crisp, and it lands well as a one-shot on a drop.
With the music
The shatter is frozen until you move it. Send B1 to Fracture so each kick throws the shards apart and they settle between hits, and a slow LFO on Tint walks the crack glow round the wheel.
Starting point
Shape on Triangles, Shards at centre, Fracture at a quarter, Prism at three-quarters, then raise Fracture until the eye starts to split.
