I recently completed my PhD thesis, where I developed algorithms for making geometric inferences from imperfect data (i.e. incomplete and inaccurate observations/representations of shapes, like broken meshes or point clouds). A thread 🧵:

New job, new papers and some new creative projects. Time for an update of rubenwiersma.nl 🎉

Having a wonderful time at the Eurographics Conference in Aachen! I gave the longest talk of my life (3h) on the biggest screen of my life and I received the Eurographics PhD award for my thesis 🎉 A huge thanks to @eurographicsc.bsky.social and all my collaborators and supporters!

I think this is a great article that puts to words something I've been thinking for a while about LLMs/AI/etc; as tools they clearly can be useful and are here to stay, but the real concern should be the effect it's having on the talent pipeline. (1/5) ergosphere.blog/posts/the-ma...

Fabulous post by @randomwalker.bsky.social & Sayash raising the same concern many of us have about whether we're on the right track with how we're using AI for science. Everyone should read it, take a deep breath & think through the implications. www.aisnakeoil.com/p/could-ai-s...

Simple idea to filter out (some) LLM-written papers with non-existent references: check the reference file agains DBLP and desk reject if a certain % of citations doesn't exist.

The materials of my graduate school course at #SGP2025 on "Deep Learning on Meshes and Point Clouds" are live on rubenwiersma.nl/deeplearning. A 'map' for 3D deep learning, covering the basics and thoughts on when and where to use deep learning tools in 3D.

Moving to sustainable manufacturing requires new computational design tools. We show how to make new objects from old "trash". 🚮 Presented on Thursday at SGP 2025 in the Fabrication session.

Holding SIGGRAPH Asia 2026 in Malaysia is a slap in the face to the rights of LGBTQ+ people. Especially now, when underrepresented people need as much support as we can possibly give them ! Angry like me ? Sign this open letter to let them know. 🏳️‍⚧️🏳️‍🌈 docs.google.com/document/d/1...

I'm sharing code&data of an unpublished project 🤯 During my PhD, I worked on applications of #computergraphics for #paintinganalysis. The main hurdle was the lack of #opensource code&data. I gathered my own, but didn't get to use it. Now I'm sharing it, so others can. 1/3 github.com/rubenwiersma...

Ever wondered how badly we're all addicted to buying new GPUs in graphics labs? Come see our talk at #SIGGRAPH2025 to discuss how we can collectively move "Towards a sustainable use of GPUs in Graphics Research" with @elie-michel.bsky.social @axelparis.bsky.social Octave Crespel and Felix Hähnlein

This was a wonderful collaboration 🤩 We developed a method that optimizes both an irregular tetrahedral grid and SDF for mesh optimization with marching tets. It recovers really detailed meshes with a fraction of the memory!

Has anyone else noticed a particular style to ChatGPT comics? I wonder if they sourced or synthesized a very ‘narrow’ dataset — or maybe it’s just confirmation bias on my end. The same for fonts.

Recent progress in multi-view 3D object capture is stunning! But is there a limit? In our upcoming #SIGGRAPH2025 paper "Uncertainty for SVBRDF Acquisition using Frequency Analysis," we show how to answer this question for material estimation. 1/6

Found some exploratory experiments I did early in my PhD: @sniklaus.com's 3D Ken Burns effect on paintings by Pieter de Hooch. Didn't go anywhere, but still looks cool. More below.

As someone who has reported on AI for 7 years and covered China tech as well, I think the biggest lesson to be drawn from DeepSeek is the huge cracks it illustrates with the current dominant paradigm of AI development. A long thread. 1/

You don't want edges on shadows in your beautiful #Blender #SIGGRAPH paper figures. An easy way to get rid of them is to go to the compositing tab, check the box 'Use Nodes' and add a 'Map Range' node on the alpha channel. Then set 'From Min' to a low value👌

The 1st SGP deadline is in 3 weeks!: if you submit, you will be notified of the acceptance decision on March 15th, leaving you with almost one month to resubmit your revised work to our 2nd deadline of April 11th (if rejected), and with over 3 months to get a visa (if accepted)

My team on "Innovation in Delft Engineering Education" at @tudelft is hiring a #PhD. We are looking for support in our "Progression and Retention of Knowledge and Skills" project. Find the job description here and please spread it far and wide: careers.tudelft.nl/job/Delft-Ph...

Highly recommended!

I can appreciate these factoids, but they're the opposite of #teaching and #education. It enforces the stereotype that math is just a bunch of meaningless rules and creates the illusion of an in-crowd that understands the deep ✨mathematical✨ meaning. Also, happy new year!

New AI Snake Oil essay: Last month the AI industry's narrative suddenly flipped — model scaling is dead, but "inference scaling" is taking over. This has left people outside AI confused. What changed? Is AI capability progress slowing? We look at the evidence. 🧵 www.aisnakeoil.com/p/is-ai-prog...

Friends in industry: As 2024 comes to a close, if your budget has room, consider joining the sponsors of the Summer Geometry Initiative (SGI)! SGI is entering year 5 with a proven track record bringing a diverse set of brilliant students into graphics/vision/ML/math research.

My superstar student Mark Gillespie is on the academic job market 🤩: markjgillespie.com Beyond lots of beautiful, deep, award-winning research in geometry processing, he's just a terrific person who we already miss having around. Twist his arm if you want him to apply!

Just want to state my appreciation for the discussions here. Feels like people are really trying to engage with each other’s points instead of trying to just win/prove their point.

Following over 1.5 years of hard work (w/@njroussel.bsky.social &@rtabbara.bsky.social), we just released a brand-new version of Dr.Jit (v1.0), my lab's differentiable rendering compiler along with an updated Mitsuba (v3.6). The list of changes is insanely long—here is what we're most excited about🧵

Please share: Our lab is looking for new PhD students starting 2025! If you are interested in research in geometry, computational design and digital fabrication, join us at EPFL! More info on the lab: epfl.ch/labs/gcm/ More info on how to apply: www.epfl.ch/education/ph...

My team RGL is looking for new PhD students starting 2025. If you are excited about topics like inverse rendering, compilers for graphics, and physically based modeling then please join us at EPFL. Info about the lab & admission process: rgl.epfl.ch/pages/jobs (Deadline: Dec 15)

I get the impression that most uses of AI images in the wild right now (posters, magazines, blogposts) are better off with good stock photography. An AI image was probably used because it was 'free' or easier to find. That's temporary, but might last long enough to harm artists in a lasting way.

When I defended my PhD last month, I wanted to give something tangible to my committee as a thank you: I would try to realize a physical version of the cover. I thought it'd be fun to share the process in a thread. 1/7

"Find your creative time and defend it ruthlessly." - Randy Pausch. I've come to realize that this statement also implies there is non-creative time where it's okay to just be. For me, it's right after lunch until about 3pm (which is obviously why I'm here right now 😅)
