Polar
VFX Loom 1.0 reference for the Polar node.

Overview
Remaps between cartesian and polar space.
Polar/radial image sampler. Wrap maps a strip into a circle; Unwrap maps a circle into a strip. In Wrap mode edges govern the radial axis.

Inputs
| Input | Type | Required | Default | Meaning |
|---|---|---|---|---|
| in | Image | Required | — | See the overview for the node's documented behavior. |
Properties
| Property | Type | Default | Animatable | Range / options | Effect |
|---|---|---|---|---|---|
| Direction | Enum | Wrap | Not declared | Strip → Circle · Circle → Strip | Selects the direction behavior; each option changes the operation described in the overview. |
| Center | Vector2 | (.5,.5) | Yes | — | Animatable control; changing it over time varies the node response. |
| Rotation | Scalar | 0 degrees | Yes | Hard -360..360 · UI range: soft | Animatable control; changing it over time varies the node response. |
| Radius | Scalar | .5 | Yes | Hard 0..1 · UI range: soft | Animatable control; changing it over time varies the node response. |
| Inner Radius | Scalar | 0 | Yes | Hard 0..1 · UI range: soft | Animatable control; changing it over time varies the node response. |
| Repeats | Scalar | 1 | Not declared | Hard 1..12 · Step 1 | Local control documented by the production node behavior. |
| Sampling | Enum | Bilinear | Not declared | Smooth · Nearest | Selects the sampling behavior; each option changes the operation described in the overview. |
| Edges | Enum | Black | Not declared | Fade out · Extend · Tile · Mirror | Selects the edges behavior; each option changes the operation described in the overview. |
Outputs
| Output | Type | Meaning |
|---|---|---|
| out | Image | The production node output described by the overview. |
Usage
In practice
- Use Polar when the graph needs Remaps between cartesian and polar space.
- Polar/radial image sampler. Wrap maps a strip into a circle; Unwrap maps a circle into a strip. In Wrap mode edges govern the radial axis.
- Use it where the graph needs coordinate or image-space movement; keep sampling and edge policy aligned with the source artwork.
Notes / limitations
- No component bounds or step is declared for Center; no step is declared for Rotation, Radius, or Inner Radius.
