Palette:pointWeight
Summary
The pointWeight component creates a weight mask based on the XYZ point data stored in the input's RGB channels. The output mask will contain zero to one values for each point based on its position, with ones inside the selection volume and zeroes outside.
The selection volume is determined by the Shape and Transform parameters. The Falloff parameters determine if the volume has a hard edge or fades off gradually.
The output image can be used to control which points are rendered using the Active parameter of the Geometry COMP instance page, or as a weight mask in the second input of the Palette:pointTransform component.

Falloff
Falloff - ⊞ - Determines how points just outside the selection volume are weighted. If the falloff is set to None, points outside the selection volume will all be set to zero. For other falloff types, the weights will fade gradually to zero.

Falloff Range Scale
Falloffrange - Controls the range of the falloff effect. Zero is equivalent to having no falloff. Values greater than zero will stretch the falloff range away from the selection volume. The falloff range is relative to any scale applied to the selection volume, so the falloff will be further along axes that are scaled larger.
Operator Inputs
- Input 0: positions - An input image containing XYZ point data in the RGB channels.
Operator Outputs
- Output 0 - A single-channel floating point image containing a weight value for each input pixel based on the point's position in space.
