Excited to share our latest work on bringing the concept of layers to 3D painting in VR! #SIGGRAPH2024

I also gather some related toughts in this appendix of the #LearnWebGPU programming guide:

"Keep in mind lower-end devices" https://t.co/gyomjU3NLp

[Élie Michel 🍪 @exppad]

The fact is that research papers are mostly tested on the very top tier of GPUs available the year they are published (and publication takes time, so they're actually even more ahead).

[Élie Michel 🍪 @exppad]

Is it because researchers only work with recent high end #GPU that everybody has to renew their hardware so fast or is the other way around?

Causality is hard to prove, but the correlation is a fact! And we have plenty more figures to show at our #SIGGRAPH2025 talk next summer!

Hi all, I’m on the job market for industry research scientist or TT faculty positions starting Summer 2025.

Interested in roles related to HCI, XR, Eye Tracking, Adaptive Interfaces, and Human-AI Interaction. Please reach out if hiring or aware of any positions!

RT appreciated!

@J_Chris_Li Thank you Jiannan! And thanks for trying it out in the early stages with me!

[Emilie Yu @emxtyu]

Work done with @fanny_uoft @karansher and Adrien Bousseau.
This wouldn't have been possible without precious insights and time invested by our study participants! The @QuillSmoothstep community is lovely, thank you so much!

[Emilie Yu @emxtyu]

We invited a few VR artists to try the tool and I also painted some things myself! So I can say first-hand, I think it's pretty fun :)

[Emilie Yu @emxtyu]

For more details, please check out our paper or come see our talk at Siggraph in Denver!

We also open-source the code https://t.co/gLljnVC3Rz

[Emilie Yu @emxtyu]

By letting artists work on a stack of apperance layers that define colors on top of a substrate layer that defines geometry, we can get many cool things!
✔️ non-destructive editing
✔️ color effects (blend modes, opacity gradients)

[Emilie Yu @emxtyu]

That issue stems from the fact that brush strokes in Quill define both the 3D geometry and the color to be rendered.
Our key idea is to decouple geometry and color, such that these two components can be edited independently with stroke-based interactions.

[Emilie Yu @emxtyu]

... or add new strokes slightly in front of the previous ones -- hard to make it work from all viewpoints in 3D.

[Emilie Yu @emxtyu]

A specific pain point we identified was on how to edit colors of 3D strokes.
In Quill, you have to either apply new colors as vertex colors -- a bit blurry and hard to control...

[Emilie Yu @emxtyu]

VR painting tools like Quill are great -- love that software! -- but they're still in the early days of defining what a painting experience in 3D could be.

[Emilie Yu @emxtyu]

We got the chance to chat with some brilliant Quill artists to understand VR painting workflows better. Turns out, in VR painting you can essentially paint all light and shadow effects, and it looks great.
Here's a beautiful example by @NickTheLadd https://t.co/6NjCBHZCNe

[Emilie Yu @emxtyu]

Hope some people find it useful and have as much fun fiddling with is as I did 😊

I’m happy to share our latest research project, where we looked at how we can assist users in creating video doodles: hand-drawn animations added on top of videos 📽️
#SIGGRAPH2023

[Emilie Yu @emxtyu]

We could not release the full pipeline to convert your own video clips to video+cameras+depth, but we do describe pretty extensively our internal format. We also provide all preprocessed videos from our paper's results to try out the system!

[Stavros Diolatzis @StavrosDiol]

Time to share our #SIGGRAPH2024 paper "N-Dimensional Gaussians for Fitting of High Dimensional Functions"!

We show that N-Dimensional Gaussian mixtures can be optimized to handle high dimensional inputs like MLPs with a fraction of the training times.
