One thing I've been wondering for years is whether I could use something like the Physarum algorithm to transport elements along the paths that form.

The issue was that the paths are transited by agents moving in both directions. Rivers don't do that.

During the Creative Code Jam last Saturday I figured out a way to have one direction per path. So nice to watch in real time :) I only had my 10 y.o. laptop, so had to work on 640x480 #CreativeCoding #OPENRNDR #Kotlin

Five poles and five zeros rotating around the center in opposite directions.

Complex numbers, 5 poles and 5 zeros.

More curves. This time colors indicate direction

Ten offset hobby contours converted to meshes and colorized using the normal of each vertex.

This is a tool I need for another project, to make things flow along contours.

Pack and go

This does something weird to my eyes...

The program no longer crashes and the fix was simpler than I thought.

Instead of comparing rounded doubles (what a silly idea) I did the proper thing, which is abs(a - b) < epsilon. A lot of times Takes maybe half second to generate the design. Then I can pan, zoom and rotate to find a screenshot I like.

I'm thinking that the lines that end in lonely places should end with a tiny knot. I may try that next.

This iteration has been a big challenge: Generate shapes, get their concave hull, pack those hulls, calculate the transformation matrices mapping the original hulls to the packed ones. Apply those transformation matrices to the original shapes. Finally play with a 2D camera to find the right shot.

And I still have an interesting rounding bug which doesn't fit in this description :)

I feel a bit guilty that this is just 4 lines of code But I still like those shapes a lot and want to send them to the #penplotter

I minimal program that draws a circle then grows 150 distorted copies of it.

The core part of the program is about 10 lines of code.

I took a walk and collected some textures to use in this one.

Not long after one of the big bangs.

Working on a new artwork.

The list of things to try is long

For 5 years we've been posting images and videos to this thread in the #OPENRNDR forum.

Maybe some day we can mark it as answered
