distortBarrel

distortBarrel(uv, strength, zoom): Node<"vec2">

Defined in: packages/nodes/src/distortion/distort.ts:124

Barrel distortion - simulates lens distortion. Commonly used for CRT screen curvature simulation.

Parameters

uv

Node<"vec2">

Input UV coordinates (should be 0-1)

strength

FloatInput = 0.1

Distortion strength (positive = barrel, negative = pincushion)

zoom

FloatInput = 1

Zoom adjustment to compensate for distortion (default: 1)

Returns

Node<"vec2">

Distorted UV coordinates

Example

// CRT-like barrel distortion
const curved = distortBarrel(uv, 0.2)
