Derivative Feedback

Derivative Feedback

Updated: 4 Dec 2023

Applies a feedback effect to a 2D field.

Method #

This node applies a feedback effect to a 2D field based on the gradient of the colours at each point in the field. This creates the effect of the field spreading out from or pulling into sharp changes in the image - e.g. lines and corners. The process is applied iteratively, so larger iteration counts will cause the effect to be stronger per frame.

This node is only effective on 2D fields.

Parameters

These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.

ParameterDetails
Position X The objects position along the local x-axis.
Position Y The objects position along the local y-axis.
Position Z The objects position along the local z-axis.
Rotation Heading The objects rotation around the local y-axis.
Rotation Pitch The objects rotation around the local x-axis.
Rotation Bank The objects rotation around the local z-axis.
Scale X The objects scale along the local x-axis.
Scale Y The objects scale along the local y-axis.
Scale Z The objects scale along the local z-axis.

Control the inheritance of the transforms from the parent.

ParameterDetails
Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.

These properties control the core behaviours of the node.

ParameterDetails
Amount The strength of the feedback effect.
Iterations The number of feedback iterations which are overlayed per frame.
