I do my PhD on physically based (differentiable) rendering, material appearance modeling/perception/capturing @tsawallis.bsky.social's Perception Lab
I enjoy photography, animation/VFX, working on my renderer, languages and contributing to open source.

Happy to announce that I will be giving a remote talk @vssmtg.bsky.social this year. I will be presenting our recent pre-print MRD: Metamers rendered differentiably (arxiv.org/abs/2512.12307).
Happy to take questions before the presentation in May, or live during the online Q&A.

MRD: Using Physically Based Differentiable Rendering to Probe Vision Models for 3D Scene Understanding
While deep learning methods have achieved impressive success in many vision benchmarks, it remains difficult to understand and explain the representations and decisions of these models. Though vision ...

Hi fellow #Neovim users!
I faced some problems with the LSP and #Slang within Neovim and finally figured out how the files need to be generated.
The solution is provided in my first Neovim plugin I've written (so bear with me), available here: github.com/pixelsandpoi...

Legit super excited about this work coming out. My amazing doctoral student @ben.graphics has been working on an idea to use physically based differentiable rendering (PBDR) to probe visual understanding. Here, we generate physically-grounded metamers for vision models. 1/4

Spiraling down the #nixOS road.
After watching this video (www.youtube.com/watch?v=dsl_...), I thought I should also have dinner. Dinner with the penguins and the snowflakes.
Let's see how far I am getting with this. Not sure I am ready.

Honestly flabbergasted by all the amazing work presented at #BCon25. It’s nice to see what everyone makes out of Blender and how far contributions can go. Definitely one of the nicest communities to be around. Superb talks, nice location, great people. Can’t wait to see you all next year again 🧡🎉

I was today years old to discover that C++ also has:
- && `a and b`
- || `a or b`
- !a `not a`

Hey #ECVP, we got our colleague @joshuamartin2902.bsky.social on BSky! Give him a follow! :)
62: Joshua will present to you how to create controlled environments to study mid-level vision.
88: I will introduce you to physically-grounded scene metamers, a method to allow you to probe your models for invariance against different physical scene parameters such as material, shape, pose, etc.

Personal highlight: Roland’s keynote. Gave me a sense of belonging.

Hot take: anyone who compares features (especially AF...) between the Sony A7IV/A7rV, Nikon Z8/Z9, Canon R5/R1, etc and says they just can't take good photos with some of those cameras but can with others... at this point that's a skill problem, not a camera problem.
