Last year we shipped a pinball game at Shopify that took some inspiration from Space Cadet. You can still play it here: https://bfcm.shopify.com/ Every year we ship a live visualiz…

I did this for years to learn computer graphics. I spent so many weekends and evenings building weird things that never made me a single dollar, but all the knowledge I gained even…

Hey mike, I'm the Diego, the person who wrote this blog post and implemented the majority of it. Reading this comment, I feel the need to challenge some of your assumptions. I don'…

Well consider this sample from the Meta Movement SDK that allows you to control the facial expressions of a character with the face tracking of the Quest Pro: https://youtu.be/IQt4…

For the arms you could use Meta's new Movement SDK: https://developer.oculus.com/documentation/unity/move-overvi... Although in my opinion the arms still look a bit janky. You can …

Wow that's super cool! That's definitely the biggest challenge - how to keep the size of the mocap data small. Our library is not the best at that, since it simply records everythi…

Holy smoke that's so cool, thanks for sharing it! I love that your work helped increase the number of morphTargets in Three.js. That's real impact!

We actually built this to easily add hands to this concept video: https://twitter.com/StrangeNative/status/1613218237969494017... Animating hands by hand (no pun intended) is horre…

It does amazingly well. Last May Meta released their Hand Tracking 2.0 update, and the quality of the hand tracking improved enormously. You can see a comparison of 1.0 and 2.0 her…

I love this so much, thanks for sharing it! We have been thinking about similar concepts at Shopify. Mocapped performances convey so much more emotion than images or videos.

Hi everyone! I'm one of the authors of this project. The demo you see here is powered by a tool that I recently helped develop and open-source at Shopify called handy. You can find…

Hi dolmen! In the "Implementation Details" section at the bottom of the README I actually explain why I only display 4 curves instead of 10, and you can change the speed of the ani…

Sorry for the confusion. Your second statement is correct. Sampling just means to evaluate the function at an appropriate t value. I will update the README to make this clearer.

Hahaha this is a fair comment. I guess my intention was to show the complex number crunching that happens in the background to make characters move. I'm still thinking about better…

Thanks proc0! What you are describing (a hierarchy of bones) is exactly what I'm doing. I decided not to mention that to simplify the explanation of how character animations work, …

To be honest I don't see this as such a bad thing. Google Chrome has 70% of the browser market share, while Safari has 4%. I don't think there's anything wrong with prioritizing mo…

Wow that's fascinating, thanks for sharing it! Although I disagree with how the author describes quaternions as black boxes. The two questions he asks: - Why does i2=j2=k2=−1 and i…

Hi suyash, take a look at the README for information on what all the little graphs represent: https://github.com/diegomacario/Animation-Magic/blob/main/RE... There's also a button …

I recommend running it on Chrome. It runs more smoothly there. I'm still improving the performance on Safari.

Oh thanks for reporting that dwrodri! Note that the controls don't work on touchscreens yet. If you use a mouse/trackpad and keyboard, you should be able to play with all the setti…

Hi everyone! I'm the author of this project. I wrote it because I think that the math that makes characters move in games and movies is incredibly beautiful, and I wanted to give o…

Hi everyone! I'm one of the developers behind this project. I wrote it with my two brothers, Daniel and Ricardo. For years the three of us have been curious about how multiplayer g…

That's a really cool idea! It's funny that you mention this because when I simulated the blocks hitting the words "Dyna-Kinematics" for the title GIF I thought: "This is what graph…

Thank you! That's exactly what I was going for :-)
