Vector Field 2D
A 2D vector field made from a picture: its silhouette and brightness become motion in one of sixteen styles — outline flow, contour bands, sweeps, zig-zags, vortices, curl noise, brush strokes along the picture's features, ripples and more. Cable Field into a Flow Map to move a texture along it, into a Particle Vector Field 2D (through the Particle System) to steer particles — one field can drive both. Region picks inside, outside or everywhere; with no picture, use Everywhere. Speed is the field's own clock for Drift and noise. Image shows the field: Color Wheel (hue = direction, opacity = strength) or Raw RG.
Inputs
| Port | Type | Default |
|---|---|---|
| EnableOff: no field — whatever reads it stands still, and the Image is cleared. | bool | true |
| ImageThe picture the field is read from: a segmentation mask, any photo, live video, a generator. Without one, choose Region Everywhere. | image | — |
| ModeWhich of the sixteen field patterns shapes the motion — outline flow, contour bands, vortices, curl noise, brush strokes and the rest. Out-of-range values snap to the nearest one. | int | 7 |
| SpeedThe field’s own clock for Drift and noise. Not clamped; 0 freezes it without snapping, negative values run it backwards. | float | 1 |
| ChannelWhich channel of the mask is read as the shape — Alpha, Red, Green, Blue or Luminance. Alpha suits segmentation masks, Luminance suits photos. | int | 0 |
| ThresholdThe level that separates shape from background in the chosen channel. Clamped to 0.0001…1; low values catch faint edges, high values only solid areas. | float | 0.05 |
| InvertSwaps what counts as inside and outside the shape. | bool | false |
| RegionWhere the motion is allowed: Inside the shape, Outside it, or Everywhere. Values outside the three snap to the nearest. | int | 0 |
| FeatherSoftens the boundary between the moving region and the still one, in Grafit units. At least 0; around 0.05…0.3 hides the hard edge. | float | 0.1 |
| Image PowerLets the mask's brightness scale how strongly each spot moves — dark areas stay put. Clamped to 0…1, where 0 ignores brightness entirely. | float | 0 |
| AngleBase direction of the pattern, in degrees clockwise. Any value works; it simply wraps around. | float | 0 |
| FrequencyHow many bands, waves or ripples fit across the view. At least 0.01; 2…20 covers broad sweeps to fine corduroy. | float | 6 |
| DriftHow fast the pattern itself slides along, on top of the picture motion. Not clamped; negative drifts the other way, 0 holds it still. | float | 0 |
| SwirlBends the field sideways, turning straight or radial flow into spirals. Not clamped; ±1 is already a full quarter-turn twist. | float | 0 |
| Center XHorizontal centre for radial, vortex and ripple patterns, in Grafit units. Any value works, even off screen. | float | 0 |
| Center YVertical centre for radial, vortex and ripple patterns, in Grafit units. Any value works, even off screen. | float | 0 |
| Noise AmountHow much wandering noise is stirred into the field. At least 0; around 0.3…1 breaks up mechanical-looking flow. | float | 0 |
| Noise ScaleSize of the noise cells — small numbers make broad rolling motion, big numbers a fine boil. At least 0.01. | float | 3 |
| Noise SpeedHow fast the noise evolves. Not clamped; 0 freezes the noise pattern and negative values reverse it. | float | 0.3 |
| ResolutionDetail of the motion grid along its long edge. Clamped to 64…1024; 256 is plenty, high values only pay off on very fine masks. | int | 256 |
| StyleHow the Image shows the field: Color Wheel paints direction as hue and strength as opacity; Raw RG packs the vectors around mid-grey for another node to read. | int | 0 |
| GainBrightens weak parts of the field in the Image so they become visible. At least 0; 1 is faithful. The Field itself is not changed. | float | 1 |
