PolarCoordinates

Convert rectangular coordinates to polar space

Props

center{x: number, y: number}

Default:{"x":0.5,"y":0.5}

The center point for polar coordinate conversion

center

{x: number, y: number}Default: {"x":0.5,"y":0.5}

The center point for polar coordinate conversion

wrapnumber

Default:1

Controls how much of the angular range to use (1 = full 360°, 0.5 = 180°)

wrap

numberDefault: 1

Controls how much of the angular range to use (1 = full 360°, 0.5 = 180°)

radiusnumber

Default:1

Controls how much of the radius range to use (affects the radial mapping)

radius

numberDefault: 1

Controls how much of the radius range to use (affects the radial mapping)

intensitynumber

Default:1

Blends between original UVs (0) and polar coordinates (1)

intensity

numberDefault: 1

Blends between original UVs (0) and polar coordinates (1)
