Impossible Paint: Asemic Writing

The Genuary prompt for day 14 is “asemic”, i.e. writing without meaning, which is something I’ve always loved. I thought it might be fun to try doing that with my watercolor simulation. Reader, I was not disappointed.

When we rerun the simulation with a different random seed each time, it comes to life in a different way. It turns out the Perlin noise that drives the brush movement isn’t affected by the seed, so “what” it writes stays the same, while “how” it’s written changes. The consistency seems to deepen the illusion of intentionality, which makes me super happy.
This isn’t my first time tinkering with procedurally generated asemic writing. That was in 1996, when I was working at PDI in Sunnyvale. There was a small group of us who were curious about algorithmic art, and we formed a short-lived club (unofficially known as “Pacific Dada Images”) that was much in the spirit of Genuary: we’d set ourselves a challenge, go off to our desks to tinker, and then meet in the screening room to share the results. The video above came from the challenge: “you have one hour to generate one minute of footage, using any of the software in PDI’s toolset”. I generated the curves in PDI’s homegrown script programming language, and rendered them using a command line tool called mp2r (which Drew Olbrich had written for me to use on Brick-a-Brac).

Genuary 2023: Impossible Paint

I love to tinker with code that makes pictures. Most of that tinkering happens in private, often because it’s for a project that’s still under wraps. But I so enjoy watching the process and progress of generative artists who post their work online, and I’ve always thought it would be fun to share my own stuff that way. So when I heard about Genuary, the pull was too strong to resist.

Here’s a snapshot of some work in progress, using a realtime watercolor simulator I’ve been writing in Unity. Some thoughts on what I’m doing here: it turns out I’m not super interested in mimicking reality. But I get really excited about the qualia of real materials, because they kick back at you in such wonderful and unexpected ways. What I seem to be after is a sort of caricature of those phenomena: I want it to give me those feelings, and if it bends the laws of physics, so much the better. Thus, Impossible Paint.

Monster Mash in Two Minute Papers!

If you’re any kind of graphics geek, you’re probably familiar with the outstanding YouTube channel, Two Minute Papers. If not, you’re in for a treat! In this series, Károly Zsolnai-Fehér picks papers from the latest computer graphics and vision conferences, edits their videos and adds commentary and context to highlight the most interesting bits of the research. But what really makes the series great is his delivery: he is so genuinely excited about the fast pace of graphics research, it’s pretty much impossible to come away without catching some of that excitement yourself.

What an honor to have that firehose of enthusiasm pointed at our work for two minutes!

Monster Mash

This past January I had the incredible good fortune to fall sideways into a wonderful graphics research project. How it came about is pure serendipity: I had coffee with my advisor from UW, who’d recently started at Google. He asked if I’d like to test out some experimental sketch-based animation software one of his summer interns was developing. I said sure, thinking I might spend an hour or two… but the software was so much fun to use, I couldn’t stop playing with it. One thing led to another, and now we have a paper in SIGGRAPH Asia 2020!

Have you ever wished you could just jot down a 3D character and animate it super quick, without all that tedious modeling, rigging and keyframing? That’s what Monster Mash is for: casual 3D animation. Here’s how it works:

FMX and Expressive 2019

Next week I’m heading to Europe for a couple of conferences: FMX (Stuttgart) where Jan Pinkava will be giving two talks about our work at Spotlight Stories, and Expressive (Genoa) where I’m presenting a paper about our look development work for Age of Sail: Non-Photorealistic Animation for Immersive Storytelling. I’m beyond excited to meet up with old colleagues and new ones, learn about the latest graphics techniques, mangle two foreign languages, and explore some cities I’ve never been to before. If you’ll be at either of these events, let me know!

“Age of Sail” at the Annies and the VES Awards

It’s not every week you have to fly down to LA twice, but what a great reason to do it. “Age of Sail” was nominated in a bunch of categories, and won Outstanding Production Design at the Annie Awards, and Outstanding Visual Effects in a Real-Time Project at the VES Awards.  I’m so grateful to have worked with this amazing team of artists, and and so proud of what we’ve accomplished together!
