bulge

Magnify or pinch the child inside a disc around center.

bulge(slots: {center: ArgSpec; strength: ArgSpec; radius: ArgSpec; falloff: ArgSpec}): UvMapSource

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

strength runs −1 to 1: positive bulges out, negative pinches in. radius sets the size of the disc (1 reaches about half the canvas height). falloff runs 0 (hard edge) to 1 (soft).

Parameters

Example

map: warps.bulge({center: p('center'), strength: p('strength'), radius: p('radius'), falloff: p('falloff')})
