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

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.

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...

I will be presenting the paper "Lipschitz Pruning: Hierarchical Simplification of Primitive-Based SDFs" at SIGGRAPH 2025 during the Best of Eurographics session! Come to my talk on Wednesday morning wbrbr.org/publications...

📜 New SIGGRAPH 2025 paper 🎉 ❔How to compute bounding volumes for procedural Signed Distance Fields (SDFs)? This is not so trivial! 💡We propose a simple method called Sphere Carving. It extracts (convex) bounding volumes around SDFs, requires very few evaluations, and is GPU compatible.

At SIGGRAPH 2025, Intel, Disney, & Chaos are doing a course on the nitty gritty details of implementing path guiding methods in 3 production renderers: Cycles, Hyperion, and Corona. I helped write the course notes: 80 pages of great stuff! Coming soon. s2025.conference-schedule.org/presentation...

Do you like voxels and implicits' representations and wish you could animate them in real-time? Now you can! Check out our article: "Real-time rendering of animated meshless representations" to know how: hal.science/hal-05095359 Shout out to @pacomeluton.bsky.social for this fantastic work!

I am glad to attend #HPG2025 where I just presented our paper "Fused Collapsing for Wide BVH Construction", co-authored with Mathias Paulin. We propose a fast build algorithm for wide BVHs that directly computes a wide hierarchy without additional collapsing pass. Webpage: wbrbr.org/publications...

In light of the recent Studio Ghibli generative models, may I recommend folks read this paper: dl.acm.org/doi/10.1145/...

We often use discretization to approximate continuous laws of physics, but it also goes the other way: You can use continuous equations to approximate the behavior of discrete systems! Here we'll see how electrical circuits can be modeled using the Laplace equation Δφ=0. [1/n]
