I'm excited to announce a first development release of nanobind 3.0. It introduces *split mode*, a new distribution model where a single Python wheel runs across all Python versions, while achieving outstanding performance and gaining rather than losing features! 🧵

TinyBVH has just been 𝘂𝗽𝗱𝗮𝘁𝗲𝗱 𝘁𝗼 𝟭.𝟴.𝟬. For CPU ray tracing, it is now the fastest option in most cases - Outperforming Intel Embree and Madmann91 for BVH build time and single-ray performance. On GPU, performance exceeds 4B rays per second - 4 rays per pixel at 4k/120Hz. github.com/jbikker/tiny...

Implicit surfaces are everywhere in vision and graphics applications that optimize shapes. If we adjust the surfaces through a "learnable" deformation field, how can we ensure they stay close to the undeformed state (e.g. a template)? Our latest paper offers a simple and effective ARAP regularizer🧵

I am excited to announce Dr.Jit 1.4 and Mitsuba 3.9 which now feature GPU-accelerated compute/ray tracing on Apple Silicon. Significant optimizations in both projects accelerate tracing/code generation ~2x. They generate better code and have faster Python bindings.🧵

This is a wildly ambitious pivot, and a lot of the pitch is wrapped up in Silicon Valley hoopla, but I'd rather that AI labs shoot for things like this as opposed to mass slop generation. This is the kind of project that has pretty unambiguous potential for good if successful.

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?

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. momentsingraphics.de/Siggraph2025...

If you work on physically-based differentiable rendering, take a look at our EGSR 2025 paper "Radiative Backpropagation with Non-Static Geometry". TL;DR: Mitsuba 3's prb_reparam and prb_projective integrators are biased when parameters affect geometry, but this unrelated to discontinuities! 1/3

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
MOTIVATION
Graphical Processing Units (GPUs) are at the core of Computer Graphics research. These chips are critical for rendering images, processing geometric data, and training machine learning models. Yet, the production and disposal of GPUs emits CO2 and results in toxic e-waste [1].

METHOD
We surveyed 888 papers presented at SIGGRAPH (premier conference for computer graphics research), from 2018 to 2024, and systematically gathered GPU models cited in the text. 

We then contextualize the hardware reported in papers with publicly available data of consumers’ hardware [2, 3].
