OMG such an honour for me !

Reminds me of photo-ops where politicians visit a job site. Look they’re wearing a hard hat and holding a hammer, they understand !

Don’t worry spaceX is going to take all that IPO money and buy a million Optimus robots.

My PhD student Abhishek Madan is getting ready to graduate and he’s looking for a postdoc or industry position. Checkout his website www.dgp.toronto.edu/~amadan/ He’s been an amazing student , basically does all his research by himself. Fantastic math and implementation acumen.

For the first time in a while none of the SIGGRAPH papers I’ll submit have any ML (no neural nets no nothing) in them. Why ? The truth is that for most of my use cases those techniques have yet to show any practical benefit over good ol’ meshes and math.

It's funny to me that the SGP call for papers basically has all of SCA as a subtopic and I'm pretty sure SCA does the same thing in reverse. It's like a snake eating its tail.

We are all just notation artists … My PhD advisor was always testing creative hacks for math notation, from using colours to different typefaces to label quantities. I like using visually meaningful decorations (like tilde for deformed quantities because it looks like a squished bar).

Hey I made a new thing - it's called Gradientspace Graph, and it's a C#-based NodeGraph Programming system that also supports inline C# and Python "Code Nodes". The NodeGraph Engine is MIT Open-Source and the Editor is Free. More details here: www.gradientspace.com/tutorials/20...

This sounds like a great course, may have to steal this idea ;)

The ACM Digital Library, where a LOT of computing-related research is published (I'd say at least 75% of my own publications), is now not only providing (without consent of the authors and without opt-in by readers) AI-generated summaries of papers, but they appear as the *default* over abstracts.

Correct

Curious what people think of bidding on papers to review for a conference. I always find this to be an unnecessary waste of time. You know my expertise and my conflicts, assign me appropriate papers, don't make me click more buttons. Agree? Disagree?

Totally forgot that the first year I ran my physics-based animation seminar course, part of the grade was writing a blog post about a paper. Those posts still exist and are quite good ! physics.diwlevin.com?p=72

One last physics assignment, this time by my student Ty Trusty, implementing vertex-block descent: github.com/tytrusty/pba... Get's about 5 chickens per second on my workstation GPU.

My worldview is being challenged The reviews received for my ICLR submission are higher quality than reviews I received for my SIGGRAPH and SIGGRAPH Asia submissions. All reviewers seemed to have actually read the paper and articulated their (reasonable) concerns in a constructive format.

When this baby hits 88 revolutions per minute your going to see some serious sh!t.

Graduate student led quest to start Canada-Wide National Laboratories focused on applied science/technology research continues ... you can visit appliedcomputing.ca to read the original letter of intent and a proposal document, plus sign said letter to show your support.

This is the best way to illustrate "I don't know what the f#@$ is going on" I've ever seen.

New fluid simulation assignment for CSC417 just dropped. This one by my PhD student Jonathan Panuelos. I had always intended to have fluid sim in the previous course but never got around to writing the code. Maybe for the best, because Jonathan's version is so good. github.com/panuelosj/pb...

From the Verge … there’s a word for this, when someone claims they own your entire personhood. It eludes me …

My PhD student Ty Trusty and a grass roots group of graduate wants to petition the Canada to start a national lab (eg INRIA) in Canada. You can read their rationale here: docs.google.com/document/d/1.... If it resonates with you, like it did me, sign the letter and share forms.gle/NqW7Q5qYkytP...!

Game 6 let’s go jays !!

Very excited to share VoMP, our surface to volumetric simready asset generator. Our method doesn’t over fit to a simulator, it predicts ground truth (as measured) Young’s modulus and poison’s ratio much more accurately then previous methods.

Don’t usually post about my non-cs hobbies but I’m proud of this :) A 440lb deadlift just a few days short of my 46th birthday

EC summary of the SigAsia 2026 decision features some real questionable reasoning On why no alternative venue ".. it sends the message that we lack confidence in our ability to host international events safely." docs.google.com/document/d/1...

The University of Toronto Dept. of CS is hiring! We have 3 tenure-stream assistant professor positions open. Toronto is a great city! Great people, wonderful nature, surprisingly good baseball team, not currently occupied by a US militia. All reasons to apply: web.cs.toronto.edu/employment-o...

As part of my new class assignments I made a simple USD writer for saving animations of dynamic triangle meshes. USD has many issues but it’s the best format I’ve found for sharing scenes like this. github.com/dilevin/usdm...

The NVIDIA HiFi team (research.nvidia.com/labs/prl/) is starting our search for summer interns. Are you demonstrably awesome at physics simulation, robotics, scene reconstruction, high-performance numerical methods? DM me your CV.

This year I'm reworking my physics-based animation course with new assignments in Python (using Torch and NVIDIA Warp). So far it's been a great set of tools to use. For the interested, here's the student code for the first assignment: github.com/dilevin/pba-...

My new number one use for LLMs is, I kid you not, spell and grammar checking Somehow ChatGPT is much better at correcting my often typo ridden drafts than whatever MS Word is doing. Turns out if you ask it to make only the minimal required changes, it will abide.

Sitting in the SIGGRAPH Asia EC town hall. Meant to be about LGBTQ+ concerns Currently we are being given tourist info about Malaysia Starting to think that the whole EC is either incompetent or just doesn't care about the opinions of their constituents.

I am boycotting #SIGGRAPHAsia 2026 because it will be in Malaysia, where there are serious safety concerns for the LGBTQ+ members of our community, thereby excluding them. I will not attend, submit my work to, or perform any reviews for SIGGRAPH Asia 2026. Yet, I'm excited about #SIGGRAPHAsia 2025!

Below is my response to being invited to serve on the technical papers committee at SIGGRAPH Asia 2026 (in Malaysia) TLDR It's a no.

I think my ideal technical talk length on a single topic is 15 minutes. Enough time to get a good sketch of the method but not so much that my attention wanders. After that I really just need to sit with the paper to have any hope of understanding.

SIGGRAPH over Tired now Or Maybe hungry Off to go solve this mystery.

This was really fun. Thanks to all the speakers. Would do again, so hopefully SIGGRAPH keeps the workshop program around.

This morning 9am East Building Room 11

Happening tomorrow morning !

SIGGRAPH Asia 2025 preemptively boycotted me … 0 for 4 on submissions this year. Well played universe !

I could not be more disappointed in the management of SIGGRAPH for this, the most spineless of PR blog posts. Count me as someone who will not have their name on any submission to SIGAsia 2026. If enough of us withhold the content they sorely need, maybe next time they will engage more earnestly.

After 6+ mos of discussion and an open letter with 600+ signatures, SIGGRAPH leadership finally responded with...a short blog post? It only obliquely *acknowledges* the issue and doesn't articulate concrete change. What are the "nuances and complexities"? Insulting. www.siggraph.org/news/listeni...

Getting ready to hop on my flight to Vancouver for SIGGRAPH If you see a guy with a weird pony tail yelling “Finite Element Method!”. It’s probably me Say “Hi”

Join us Tuesday night at #SIGGRAPH Real-Time Live show to see interactive painting with Gaussian splat brushes, awesome work (and technical paper) by Karran Pandey presented by him and our inspiring collaborators at the National Film Board of Canada!

Me,Peter Chen and Eitan Grinspun are hosting a SIGGRAPH workshop on reduced-order models. Great keynotes from Maurizio Chiaramonte (Meta), Jernej Barbic (USC) and Mengyu Chu (Peking University) plus a bunch of awesome lightning talks. Come check it out: roms.news

When you sign into Microsoft 360 this dystopian vision of the future is what greets you. Welcome to your office tools, AI is stalking you.

I am still having very mixed experiences with the TOG timelines. One paper sailed through in 4 months, another one has been under review for almost a year. Not great variance if you care about sharing fresh ideas with the community. Would love to understand ... is it just growing # of submissions?

Code is now out! Try it for yourself here: github.com/abhimadan/st...

I want to make fun of this but it’s eerily similar to how I actually dance

Update on all of this — we have been informed no reply from conference management yet Cmon ACM, don’t ghost us Have the courage to say you don’t care about the concerns of hundreds of community members in general and the LGBTQ+ community in particular.

I assiduously train my grad students no to trust authority out of hand. It is very annoying when they apply that to me.
