Personal holding up a watercolor painting of a mango blossom with turquoise, purples and reds.

Close up of a water color of a mango blossom using reds, maroons ands shades of yellow.

Mango Blossoms - 22x30”. Programmatically generated, drawn with pen plotter and then water colored by hand.

Close up of water color paper with pen markings depicting a plant like structure.

Close up of a water color paper depicting the stem of a plant that has been colored varying shades of red with water color.

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".

Tried some nice brush tip markers on this recursion error plot. #penplotter #genart #openframeworks

My favorite part, water coloring the pen plot by hand. Testing out colors. #penplotter

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

Endless recursion bug making branches; #plotterart #generativeart #openframeworks

Black pen drawing on white paper, an algorithmically created branch resembling a mango branch.

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

Pen plotter drawing of downward facing stems with programmatically created flowers along them.

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

Osc sending and receiving is also supported.

Lines run around the face, eyes, mouth, torso and hands of a person holding up two fingers.

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

Excited to share our latest project: "Dream Garden" a whimsical, immersive experience by @design-io.bsky.social at The Tech Interactive museum in San Jose. www.thetech.org/explore/exhi...

Algorithmically generated plant drawn on white paper with a pen plotter.

Two images side by side. The image on the left shows a line thicker than 1px and the image on the right is 1px thick after applying a thinning algorithm.

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

Water color painting of a black dog holding a broken tennis ball in its mouth.

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. 🤗

Thanks for the suggestion. :) Just quickly tried Illustrator, but couldn't get the results I am looking for by playing with the parameters.
Ideally, the final pipeline would be generate 3D mesh -> outlines -> svg from a single app.

Lines depicting an edge detection algorithm where red is difference in normals, g is depth and b is color.

Output in black and white as a line drawing with the goal of being 1 pixel wide. On the right is multiple color outlines showing many different lines composing a line drawing of a stalk of flowers.

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 :/

@rezaali.bsky.social thank you; fairly satisfied with the output of the edge image I have so far so I'd like to utilize that. I can dig into the vision framework more tonight about using it to extract lines from the current edge image.

Render of computer generated flower objects. On the left side is a line style output depicting the edges generated from a shader, with red showing difference in normals, g in depth and b in color. The right side shows the flowers as meshes.

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?

Acrylic laser cut stencil with the words Kind Love in the center

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

Debug viewing our recently launched project at the Maritiem Museum in Rotterdam with Design I/O.

I first started using CA glue for its wood working applications as a quick clamp. Using an accelerator it cures instantly. It's very handy to have around, most recent glue ups:
☑️ Pretzel to hair clip
☑️ Purse Latch
☑️ Magnet to wood
☑️ Small Figurine
☑️ Earring backing
☑️ Fingers

Just in time for the holidays!
