toPolar

Unroll the child around center, so angle becomes x and distance becomes y.

toPolar(slots: {center: ArgSpec; wrap: ArgSpec; radius: ArgSpec; intensity: ArgSpec}): UvMapSource

Import warps from shaders/std and use warps.toPolar.

wrap scales how many times the child repeats around (1 is once). radius scales the distance axis. intensity runs 0 (no change) to 1 (the full polar unwrap), and the values between are a real partial warp, not a cross-fade.

Parameters

Example

map: warps.toPolar({center: p('center'), wrap: p('wrap'), radius: p('radius'), intensity: p('intensity')})
