Great experience on Southwest WN 3502 today; I forgot a piece of expensive electronics in the terminal.
Passengers can’t exit after boarding, but after overhearing my plight, the pilot volunteered and found it and brought it back! The day was saved! Thank you! @SouthwestAir

You can transform a simple verlet ballpit into a “viscoelastic” simulation just by increasing the range of the collision distance constraint to a little beyond each object’s radius.
This attracts them to each other while also handling collision.

For anyone who is interested in implementing our new method Augmented Vertex Block Descent (AVBD), you can find the source code for the 2D demo implementation here: github.com/savant117/avbd-de…
You can also play with the demo in your browser!

Introducing 𝗥𝗼𝗯𝗼𝗣𝗶𝗮𝗻𝗶𝘀𝘁 🎹🤖, a new benchmark for high-dimensional robot control! Solving it requires mastering the piano with two anthropomorphic hands.
This has been one year in the making, and I couldn’t be happier to release it today! Some highlights below:

First, if you enjoyed the video above, we have a live demo that runs MuJoCo in your browser using Javascript and Web Assembly! You can accompany the robot (drag the keys down), or be adversarial and tug at the fingers 🙃

Long time coming! This was so much work and I can't be more happy that it's finally out there :D
SteamVR driver next so not-linux-nerds can use it with Index!

Today I'm open-sourcing Tangle: a new library that automatically 'entangles' and syncs WebAssembly.
Play with the demo: tanglesync.com

I'm much happier working on environmental topics now, but I stumbled on this video and it's fun to think back to working on futuristic AR tech once upon a time
