Cool. I posted a while ago about fast CDF reconstruction. I wonder if you are doing something like this or have a different technique. maxliani.wordpress.com/2024/03/09/a...

Ever seen one of these, and wondered *why* they work? 🧵 This is a so-called Bitonic sorting network, and the illustrations show the two common ways to implement them. From an implementation point of view the two methods are effectively the same, so which one you pick just comes down to preference.

I'm finally writing up how Nanite Tessellation works. The first few blogs posts are up. More will be coming. graphicrants.blogspot.com/2026/02/nani...

New post on how to do real-time diffuse global illumination using surfels and #WebGPU: juretriglav.si/surfel-based... #threejs

This was a fun quick experiment: Using an old photo I took in the forest, I used ml-sharp to generate gaussian splats from it, voxelized it in my toy renderer, relit the scene dramatically. #rendeting #metalrt

Geogram flies ! The other day, I was reading this article from NASA Ames Research Center: ntrs.nasa.gov/api/citation... What do they use for the geometric computations ? Geogram of course ! (thrilled !!) Geogram is a library with geometry processing algorithm: github.com/BrunoLevy/ge...

Gaboronoi (top) vs Anisotropic Voronoi (bottom), with 5000 Sites. I feel like the anisotropic voronoi's artifacts are more aesthetically pleasing. Gaboronoi is faster to train by a lot! I've compiled all of my recent voronoi experiments into a collab: colab.research.google.com/github/jaker...

My "How to Vulkan in 2026" @vulkan.org #Vulkan guide is now publicly available at www.howtovulkan.com I still consider it a preview, though I'm mostly happy with it and only plan on changing minor things and incorporating some feedback.

My "No Graphics API" blog post is live! Please repost :) www.sebastianaaltonen.com/blog/no-grap... I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

Posting an older article on "Probability Theory for Physically Based Rendering", using tomorrow's #thisisigad Graphics Guild lecture as an excuse: jacco.ompf2.com/2019/12/11/p... There is also a part 2.

So Apple put out an article this week about how they are now 3D printing titanium parts in large volumes for Apple Watches and iPhone Air; this is a bit of a surprise and really cool! (1/3) www.apple.com/newsroom/202...

The Graphics Replicability Stamp Initiative (GRSI, www.replicabilitystamp.org), a community-driven initiative to promote replicability in Graphics research, is seeking volunteers. More details in the 'Volunteering' section of the home page.

There's a new and very neat-looking SIGGRAPH Asia paper on constructing the swept volume based on the path of a moving (possibly deforming) object. Check it out! https://jurwen.github.io/Swept-Volume-Page/

Here's a great video explaining/showing why the common CG practice of plugging smudge/fingerprints/dirt/whatever maps into roughness is wrong and why it should be done using material layering instead. This video is really well-made! www.youtube.com/watch?v=OW4L...

apparently there are also native sdf nodes in blender 5 now

i wrote an efficient convolution reverb for dreams while at mm years ago, and found myself in need of one again. my memory was hazy on the details, and i couldnt find it written out in a simple way i could immediately understand, so i chewed a pencil and reminded myself. heres how i think about it

New blog post! In "Billions of triangles in minutes" we'll walk through hierarchical cluster level of detail generation of, well, billions of triangles in minutes. Reposts welcome! zeux.io/2025/09/30/b...

Couple pieces about this work - about the sphere packing, using voxel "dart throwing" on the GPU: jbaker.graphics/writings/sph... about the reuse of the data structure from the sphere packing, reinterpreting it as a grid-based raytracing acceleration structure: jbaker.graphics/writings/dda...

Super proud to have been part of this work led by Sam Bourgault and Alejandro Aponte @ expressive computation lab With WORM, we propose a new way to program cobot manufacturing actions through skilled manipulation and procedural repetitions Checkout the paper and demo at #UIST2025

Is #geogram's Constrained Delaunay Triangulation robust ? ... on the testbench ! github.com/BrunoLevy/ge...

RING meeting in Nancy, Cyprien Plateau--Holleville presented presented his awesome work on exact integration of the differential quantities involved in Partial Optimal Transport. And that's not all: It comes with a combined physsim - Optimal Transport - rendering on the GPU !

Our article "Large-scale semi-discrete optimal transport with distributed Voronoi diagrams" (with Nicolas Ray, Quentin Merigot and Hugo Leclerc) just got accepted by Journal of Computational Physics. Pushing the limits of Optimal Transport by several orders of magnitude !

Anyone here have experience PyPI packaging of custom nanobind bindings for CUDA code specifically? I'm fairly good at pybind/nanobind for standard C++ stuff, but I don't even know where to start for GPU code, especially one that links to Nvidia's proprietary libraries. pls halp 🙏🙏🙏

🚀The code for Lipschitz Pruning is now online thanks to @wbrbr.bsky.social🚀 🔗 github.com/wbrbr/Lipsch... It's a simple Vulkan app useful for experiments. Also, the monument done by @elie-michel.bsky.social is released under a CC-BY license📄 (poke @mattkeeter.com I remember you asked!)

"By systematically contaminating inputs with NaN and observing which outputs become NaN, the method reconstructs conservative sparsity patterns that eliminate a major source of false negatives." absolutely incredible, and also someone needs to stop these people arxiv.org/abs/2507.23186

Playing with CSG engine, stress test, example_024 from OpenSCAD testsuite, but level 5 (instead of level 3 by default). Constrained Delaunay Triangulation goes brrr.

Presenting this paper tomorrow morning at 9:30am, during the Lightning Fast Geometry session⚡ Come check it out if you can!

Differentiable rendering has transformed graphics and 3D vision, but what about other fields? Our SIGGRAPH 2025 introduces misuka, the first fully-differentiable path tracer for acoustics.

At 3:45 PM tomorrow at SIGGRAPH, Lea Reichardt and Marco Manzi will present our part of the "Path Guiding in Production" course. Lea and Marco will talk about how we've been bridging cutting edge research into production in Disney's Hyperion Renderer. s2025.conference-schedule.org/presentation...
