blurKawase

blurKawase(tex, uv, offset, texelSize): Node<"vec4">

Defined in: packages/nodes/src/blur/blurKawase.ts:23

Kawase blur - fast, iterative blur technique. Used in many games for efficient bloom/blur effects. Each iteration doubles the effective blur radius.

Parameters

tex

Texture

Source texture

uv

Node<"vec2">

UV coordinates

offset

FloatInput = 0

Current iteration offset (increases each pass)

texelSize

Vec2Input = ...

Size of one texel in UV space

Returns

Node<"vec4">

Blurred color for this iteration

Example

// Multi-pass Kawase blur
let blurred = blurKawase(texture, uv, 0, [1/width, 1/height])
blurred = blurKawase(blurred, uv, 1, [1/width, 1/height])
blurred = blurKawase(blurred, uv, 2, [1/width, 1/height])
