Envelope or thread art

Here is a fun processing exercise, G’MIC or otherwise.


Hard mode
A heightened challenge would be to make a colour image, where the overlapping and obscuring is physically possible.

Better idea. Flow field art. I have yet to see this in gmic.

1 Are the lines in linify of single colours?
2 Does it support a “circular loom” like in the video?

Wouldn’t masking and setting a fill color layer to color blending mode would solve these problem? Post-processing manually by hand in either Krita or GIMP? Actually both can do it nondestructively.

Option 1

Layer 3 = Alpha Circle (Destination In Blending Mode)
Layer 2 = Fill Color of your choice (Color Blending Mode)
Layer 1 = G'MIC Layer

Option 2

Group Layer Masked with Circle Mask
-- Layer 2 = Fill Color of your choice (Color Blending Mode)
-- Layer 1: G'MIC Layer

Personally, I would choose the 2. In Krita, there is also:

A Layer with HSV filter-mask set to colorize, and a circle transparency mask

Can Linify be expanded with splines instead lines to look more organic?
