Field Position-Based Warp

Field Position-Based Warp

Warps an image based on the movement vectors of an input field.

image

Method #

This node warps an image based on the movement vectors of an input field. The field movement vectors are used to deform a position lookup grid over time, which is then used to sample the image every frame. This allows animating deformations to be applied to separately animating sources.

The processed texture above has been altered from default to show the kind of effect you can get with this node. By default, no change will be made to the node until you input a field root system.

Parameters

These properties control the core behaviours of the node.

ParameterDetails
ActiveEnables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Blend AmountChanges the opacity of the new effect over the original image.
Blend Mode (RGB)Change how the generated effect blends with the parent image RGB.
Blend Mode (Alpha)Change how the generated effect blends with the parent image alpha.
Simulation SpeedControl the speed at which the warp is animated.
Velocity ScaleScales the velocities of the input field.
Displacement ScaleScale the amount the field root effects the image.
Velocity DampeningDampen the effect of the field root.
BrightnessScales the brightness of the result.
WidthControls the width of the underlying deformation grid. the greater the width of the grid, the more memory intensive the processing is but the sharper the result.
HeightControls the height of the underlying deformation grid. the greater the height of the grid, the more memory intensive the processing is but the sharper the result.

Toggle which of the RGBA channels are affected by the effect.
