Inputs

Surface
The surface value.

Seed
A surface image with the seeds for the groups.

Color
A surface image used to color each group.

Outputs

Surface
The surface value.

Groups
A surface image with the index of each group.

Geometry
A surface image with the center and borders of each group.

Color

Attributes Panel

Surface Filter attributes

Num Groups
The number of groups in which the surface is divided.

Min Size
The minimum size of each group.

Seed
A random seed that changes the group distribution.

Random generation of group seed.

If no input seed image is used, the group seeds are randomly generated.

Surface Filter Out Groups output

Surface Filter Out Geometry output

Surface Filter Out Colored output from a Random Noise image.

Image Seed

If an image seed is used, the groups are generated from the opaque pixels of the image (alpha = 1.0). The same image can be the seed and color input.
