I have procrastinated on writing so much that I wrote an entire document on writing tips: cseweb.ucsd.edu/~tzli/writin...
Probably not much is new but I find I still need to repeat the same things to my students regularly. Will update this document over time hopefully.

I gave an internal talk at UCSD last year regarding "novelty" in computer science research. In it I "debunked" some of the myth people seem to have about what is good research in computer science these days. People seemed to like it, so I thought I should share.
Announcing SGI 2026! Undergrads and MS students: Apply for 6 weeks of paid summer geometry processing research. No experience needed: 1 week tutorials + 5 weeks of projects. Mentors are top researchers in this emerging branch of graphics/computing/math. sgi.mit.edu
The EU/Europe and all NATO Partners need to put an end to what the Trump admin is doing and planning to do. The Greenland people are sovereign and decide their future. If the U.S. attempts to militarily annex them that is tantamount to war and subjugation.

Fantastic presentation, worth a watch!
Check out our recent SIGGRAPH Asia paper on differentiating programs that integrates over discontinuous functions (yes, again), which got the best paper award! yashbelhe.github.io/asd/index.html
The first author Yash is looking for a job yashbelhe.github.io so talk to us if you're interested.
After nine years of development, meshoptimizer has reached its first major version, 1.0!
This release focuses on improvements in clusterization and simplification as well as stabilization. Here's a release announcement with more details on past, present and future; please RT!
meshoptimizer.org/v1
Wolfgang Straßer's PhD thesis being cited for its one-page future work section really shows how unpredictable 'impact' can be in research.
Funding: if your mid/large business uses Dear ImGui - and maybe you are approaching end of year budget/planning etc. - please consider reaching out (PM/email) so I can help you help Dear ImGui !
I gave a talk at Pacific Graphics 2025 on the topic of "Classical Computer Graphics in the Age of Generative AI". I've uploaded the recording to Youtube today.

A cloud rendered using jackknife transmittance estimation and the formula used to do so.
Ray marching is a common approach to GPU-accelerated volume rendering, but gives biased transmittance estimates. My new #SIGGRAPHAsia paper (+code) proposes an amazingly simple formula to eliminate this bias almost completely without using more samples.

Please meet @afectivo.bsky.social . This is a new firm my partner and I are starting in Madrid, Spain. For now we are doing consulting work (in audio and outside of audio), but we have other exciting technology projects and initiatives in the pipeline we hope to be announcing in the coming months.
Thanks!
Beautiful project! Do you have any recommendations for literature on relativistic ray tracing (and practical implementations)?
Depends on the community you're looking for. I'm happy with the number of 'graphics researchers and programmers' here on Bluesky. I don't feel like I'm really missing out on anything since leaving twitter.
Dr.Jit+Mitsuba just added support for fused neural networks, hash grids, and function freezing to eliminate tracing overheads. This significantly accelerates optimization &realtime workloads and enables custom Instant NGP and neural material/radiosity/path guiding projects. What will you do with it?
I found this to be a great reference: github.com/rgl-epfl/cho...
The kernels are precompiled to PTX and shipped with the PyPI package. On the user machine, they are JIT compiled using the CUDA driver API (dynamically loaded). However, this doesn't link any library, so might not be what you need.

This is joint work between the computer graphics and audio communication groups at TU Berlin, with @ugoalone.bsky.social, @tjueterb.bsky.social, Daniel Wujecki, Fabian Brinkmann, Stefan Weinzierl, and Marc Alexa.
We extend Radiative Backpropagation (by @merlin.ninja)/Path Replay Backpropagation (by @deliovicini.bsky.social), to time-dependent energy transport, enabling backpropagation in linear-time with constant-memory. Despite simulating time-dependent functions, we only need one additional scalar per ray!
Our key observation is that this duality between acoustics and graphics lets us apply concepts from physically-based differentiable rendering to acoustics, enabling gradient-based optimization of acoustic objectives.
The simulations assume that energy travels along rays and even the rendering equation is the same as in graphics! Almost, at least. Time is an additional parameter, because sound cannot be assumed to travel instantaneously.
Room acoustics design, for example of concert halls, is currently a time-consuming process: engineers often semi-manually tweak a room's geometry and materials in long simulation loops to improve characteristics like clarity.
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.
Methods like NeRF and Gaussian Splats model the world as radioactive fog, rendered using alpha blending. This produces great results.. but are volumes the only way to get there?🤔 Our new SIGGRAPH'25 paper directly reconstructs surfaces without heuristics or regularizers.
Physically-based differentiable rendering enables inverse rendering, but handling visibility is hard. Our SIGGRAPH
2025 paper uses quadrics to importance sample silhouette edges--outperforming all existing unidirectional differentiable path tracers.

EurIPS is coming! 📣 Mark your calendar for Dec. 2-7, 2025 in Copenhagen 📅
EurIPS is a community-organized conference where you can present accepted NeurIPS 2025 papers, endorsed by @neuripsconf.bsky.social and @nordicair.bsky.social and is co-developed by @ellis.eu

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.

Feel free to reach out to me at the conference or via mail.
Special thanks to @wjakob.bsky.social for his valuable feedback and for giving us the historical context for the original papers.

The reason lies deeper in the theory of radiative backpropagation (RB), the technique underlying these integrators: it was derived under the assumption of static geometry. We extend this theory to non-static geometry and show how the simplicity of RB can be retained in this case. 2/3
