Image Emitter
Updated: 4 Dec 2023
Emits ink into a field from an input image.
Image Emitter
Method #
This node emits colour/ink into a field based on an input image, useful for making 2D field effects based on a video feed.
The outputs from this node are just its transforms, useful for having multiple nodes follow the same motions without controlling each of their transforms individually.
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.
Parameter Details 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.
Parameter Details 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.
Parameter Details Colour Image The image used for the field. Can be overrided by an input image or video.
Amount How strong the emitter is on the field.
Blend Mode How the emitter blends into the field. See Blend Modes for details.
- Solid : The emittedd ink replaces all the field.
- Linear : The emittedd ink is blended with the field.
- Additive : The emittedd ink is blended with the field.
- Subtractive : The emittedd ink is subtracted with the field.
- Max : The emittedd ink is uses the max value compared to the field.
- Min : The emittedd ink is uses the min value compared to the field.
- Light : The emittedd ink is blended with the field using the light blend mode.
- Screen : The emittedd ink is blended with the field using the screen blend mode.
- Premul Blend : The emittedd ink is premultiplied against its alpha before blending with the field.
Emit Once When enabled, the object will only emit ink once into the field.
