Swirl
Swirl
Use Swirl to create angular rotational distortion around a configurable center. The twist is strongest near the center and falls off with distance, producing smooth spiral effects useful for water, galaxy, and organic form deformation.
Availability
This node requires Pro.
Common uses
- Lower intensities produce subtle twisting; high intensities create tight spirals.
- Adjust center point to offset the swirl origin from the canvas center.
Input ports
-
input -
Requires an image input to distort.
Output ports
-
out -
Outputs the swirl-distorted image with the same dimensions.
Parameters
| Parameter | Type | Default | Range or values |
|---|---|---|---|
| Intensity | float | 0.25 | 0 to 10 |
| Center X | float | 0.5 | 0 to 1 |
| Center Y | float | 0.5 | 0 to 1 |
| Direction | enum | cw | cw, ccw |
Behavior
- Swirl applies a radial rotation offset proportional to distance from center.
- The twist angle is intensity * (1 - distance_from_center / max_distance).
Common mistakes
- Very high intensity can produce extreme twisting at the center that may alias.
- Tiling may introduce seam artifacts at the edges with strong swirl.
