Now two examples with just two layers, a top layer for the lines and a bottom layer to color the cells. Here’s one with 200 rectangles. Because cells are colored with index equal to n/Nmax, shuffling the colors often gives a more pleasing result.

The original rectangle can also be divided into triangles. A few parameters are different. The first division of the rectangle can be into two, three, or four triangles. If two, a diagonal line crosses from corner to corner. If three, a point on one side is connected to two opposite corners. If four, a point in the center is connected to all four corners.

After the first division, triangles can be divided into two or four triangles. If two, a point on one side is connected to the opposite corner. If four, points on all three sides are connected to each other. Experiment.

This looks like fun, Jim - thanks very much for working up the code for this plugin for us!

The rectangular cells function of this reminds me of Matting and Framing* which produces various cell arrangements as well... but is hellishly complicated to use. You really need to think everything through meticulously and plan how to merge cells and whatnot manually to get the result you want. I just don't have the focus or patience needed for that. Your solution is both fun and quite easy to use though I appreciate it serves more as a fun mosaic-like effect than a practical framing function.

*This is an OCA in rkb.ucl. Is that the one you were thinking of when you mentioned rkb.ulb in your first post here? I still have Matting and Framing in my formulas.

Thanks, Chris,

No, I was unaware of Matting and Framing in rkb.ucl. It's over 4400 lines long, so it's not easy to understand how to use it n(an understatement).

What I had used (and still can, because somehow I saved an old copy of rkb.ulb) is Mondrian Maker (Layout), which is one of rkb's own variety of trap shape plug-ins to his outside coloring One Shape in rkb.ucl.

I'd be interested in unusual uses that someone might find for Cells. For instance, below is a 20,000-cell upr that could be used as a layer to provide some noise-like adjustment in a fractal. (No need to provide an image.)

I think that the only limit on the number of cells is computer memory. I've done up to 100,000 cells. It makes no sense to make cells smaller than a few pixels on a side.

Robert Bunney did provide some information and instructions for Matting and Framing on his Verizon website (now defunct) at the time of release. Being a bit of a hoarder I have a 21-page .pdf tutorial saved that he wrote to explain it all. It makes sense when you read it but the OCA IS hard work and I don't think I ever found a need for it or used it! I have example frame layers saved as well - all very clever and interesting and fancy but never used.

Let me know if you want a copy to look at.

Yes, I can see your random squares texture might be of use but, to be quite honest with you, there are other things like that texture that are not so CPU intensive. SFBM II for instance or Voroni texture are two possibilities that I would probably use in preference.
