Some quick notes on my findings using different water color papers with a #penplotter using a micron pen and water colored by hand afterwards.
My favorite are the Arches Hot Press papers at 22x30".

Controlling the creation of plants using your hand. Palm orientation for grow direction, pointer and middle finger distance to thumb for flower scale and open respectively. The branches of the mango plant (first one) take on the shape of your ring and pinky fingers. #openframeworks #generativeArt

Drawing some inspiration from the mango blooms in our backyard. Some test prints on 9x12. Made some optimizations connecting lines. Number of lines when from > 5500 to < 800. Plot time went from 35 -> 20 minutes (for the close up one). #penplotter made with @openframeworks.bsky.social

The output from the #penplotter. The lines are a bit "organic" from the smoothing.

Multiple branches for the fish tail palm. The end of the video is the output lines for sending to the #penplotter. #openframeworks

Trees that grow leaves, flower, bear fruit and drop leaves are controlled and mapped to a person's body. MediaPipe is used for the tracking.
During the project we developed the #OpenFrameworks addon ofxMediaPipePython github.com/design-io/of... @theowatson.bsky.social

Got a bit side tracked updating a svg addon for #openframeworks so I could save the output of the 3D model line detection for plotting. The thinning algorithm brings it all down to a 1px line and then I run through and connect them. The lines are then smoothed with Savitzky-Golay filtering #plotter

I painted this water color for my brother and received “Real-Time Rendering Fourth Edition” and GPU Zen “Advanced Rendering Techniques” as a thank you. 🤗

Running the output of the edge detection shader through the Zhang-Suen thinning algorithm ( b & w ), then ChatGPT giving a go at the CPU lines; Each line is a color. Unsatisfied with the result.
Going to think of it as way finding for a lost creature.
Compression is unkind to thin lined images :/

Using a shader to detect edges from a G Buffer. The left shows a combination of normals (R), depth (G) and color(B) differences using a Sobel kernel or similar.
Now I would like to get the lines from the image into a vector of lines on the CPU. Not looking for real time. Any suggestions?

This drawing by my daughter resonated with us so I made a laser cut stencil and we spray painted it onto shirts.

I received an A1 size pen plotter as a generous gift and it needed a place to reside for easily making plots. I decided to make a project table and it's finally finished. More details about the process in this post: nickhardeman.com/942/project-...
