Layered Paper Experiments

Recently I’ve been experimenting with the effects of layering paper designs over each other. I’ve seen other people do this (Glowforge’s twitter account just posted a link to this today but these are my first attempts.

I create the designs by coding them in Processing. Each is about 4 inches wide (so I can cut several layers at a time). The paper is 90lb bristol.

Separately, I’m trying to figure out how to use this method with drawings. I’m not sure if the photo shows it but the layers gradually reduce as the layers build so there’s a 3D relief to it. There’s still a lot to figure out. (What happens if you paint different layers different colors, give it different backgrounds, intentionally misalign the layers, etc. )

Very cool! (I plan to try it one day too.) :grinning:

Nice. Please continue to share as you explore this technique.

Good work. The char on the paper edges really adds something

Love it!

Are you building them in processing/java and saving as SVG? I’d love to hear more about your workflow/process.

I was debating between processing, p5js, numpy/scipy/python, etc… And right now I’m leaning towards penplot/javascript.

I daydream that as I get proficient I can build a tool to help visualize/simulate cutting via SVG to see what the layers would look like. (kinda like how fusion 360 simulates the CAM steps for CNC machines)

Right now I’m trying to focus on making things (art), rather than software as I tend to spend too much time building tools and not building art :slight_smile: “know theyself”

I’m trying to think of a way to visualize my workflow, bu the short answer is I do not save directly as an SVG. I think you CAN, but for some reason I decided a while ago it was better just to save as PNGs then convert and trace them in photoshop and Illustrator. Possibly because of control over sizing? I should look back into it.

PNGs also let you view the individual files on my work computer where I don’t have the imaging files (but do have the spare time to fool around with experimenting with the code between assignments).

I’d post the actual processing code but it’s probably inelegant and hard to understand what’s going on. The great thing is that once you get started in a direction you can change the shapes, variable, etc. really easily. And you can add bits to help you with your workflow.

For instance, I have it set up with a “preview” mode so I can get a really basic idea of what the finished, layered work will look like. (And when the sketch is run the layers will be be added 1 at a time so it’s more clear than this.)

And here are thumbnails of the individual frames for that sketch (the red section would be the middle line in each frame. I only made it red to clarify the parts enough to see the structure):

You can also make other scripts that will do some of the work of preparing them to cut. For instance, once the individual layers are created, you can have another preocessing sketch that automatically resizes them and arrays them next to each other into sheets the size of the paper you’ll be cutting (so at 4" x 4" I can fit 4 of these on a single 12 x 9 sheet of paper) so I only have to trace 4 images in illustrator to cut everything. It also allows me to taper the edges of each frame, which is an effect I like.

All told, it’s a really efficient process after you chug through the initial stage of coding (all these designs have been relatively slight variations in a single concept. Plot a line/ellipse/wavy line, rotate it). The possibilities are really endless and the designs are soooo clean. In the past I’ve also used the Glowforge to engrave wood blocks that I’ve used to print using a hand cranked press which is another way to get a physical object out of the generative code.

There’s a javascript version of processing, so they work well together. I think the adobe suite also uses JS to run macros, so you may be able to kill a bunch of birds with relatively few stones if you go that route. It isn’t the mode I’ve used though.

Oh and for the drawing of the guitar guy I doodle on my Galaxy Note during my commute
