It's getting to that point where our research team is thinking about next year's interns. If interested, feel free to e-mail me, or (even better) find someone on our team whose research aligns with yours and e-mail them. research.nvidia.com/labs/rtr/

Khronos has announced the launch of the new Slang™ Initiative. This initiative will oversee and advance the open-source Slang shading language and compiler, building on 15 years of research, development, and deployment experience by NVIDIA. Learn more: khr.io/17f

I'm always a bit shocked when I forget how to "hat" something in LaTeX, and the regrettably google "latex hat". 😂

NVIDIA has just released Vulkan samples for RTX Mega Geometry. They should run on all RTX GPUs using the new drivers: github.com/nvpro-samples/… github.com/nvpro-samples/… github.com/nvpro-samples/… github.com/nvpro-samples/…

If you’ve ever wanted to train your own gaussian dataset, this handy new framework just went live: github.com/nv-tlabs/3dgrut

The rationale for reservoir sampling wasn't clicking for me but then someone wrote this samwho.dev/reservoir-samp… Thank you Sam Rose

SOBB: Skewed Oriented Bounding Boxes for Ray Tracing Kácerik Martin, Bittner Jirí diglib.eg.org/items/f17ede08… Abstract We propose skewed oriented bounding boxes (SOBB) as a novel bounding primitive for accelerating the calculation of rayscene intersections. SOBBs have the same

Our upcoming HPG 2025 paper ”Collaborative Texture Filtering” is up! Research done with Pontus Ebelin, Matt Pharr, and Bart Wronski 🇺🇦🇵🇸. research.nvidia.com/labs/rtr/publi…

📢📢We have a last-minute internship opening on my team at NVIDIA AI for this summer. If you are interested and have experience with large feedforward reconstruction models or post-training image/video diffusion models, please get in touch!

GSCache: Real-Time Radiance Caching for Volume Path Tracing using 3D Gaussian Splatting Contributions: • We introduce a novel radiance cache optimized for volume rendering that caches path-space radiance using multiple levels of Gaussian splats. • The cache works in real time

🌲Introducing our paper A generalizable light transport 3D embedding for Global Illumination arxiv.org/pdf/2510.18189. Just as Transformers learn long-range relationships between words or pixels, our new paper shows they can also learn how light interacts and bounces around a 3D

I am excited to announce the release of Radical Pie, version 1.0! This is the professional equation typesetting application that I've been working on for the last year. See the website for details. radicalpie.com

I am excited to share our #SIGGRAPHAsia2025 ToG paper, co-authored with Eugene d'Eon, Rohan Sawhney, and my PhD advisor Wojciech Jarosz. We introduce a new method that accelerates Walk on Spheres (WoS) by orders of magnitude.

Excited to share our new paper, “Materializing Inter-Channel Relationships with Multi-Density Woodcock Tracking,” IEEE TVCG! (to appear) Huge thanks to my co-authors: Stefan Zellmann , Haichao Miao, Nate Morrical , Ingo Wald , Valerio Pascucci Preprint: alpers-git.github.io/personal-websi…

In this paper is proposed Gabor Fields, a new volumetric primitive fields that enables continuous frequency filtering at no cost, enabling continuous LoD control, reduced rendering time, and a trade-off between variance and bias for performance. arxiv.org/pdf/2602.05081

In 2026, I reprise my role as High-Performance Graphics papers chair, joined by Markus Kettunen. The papers deadline is 8 weeks from now. Submit your performance-oriented graphics research and present it in Los Angeles, just before SIGGRAPH (July 17-19 2026)! highperformancegraphics.org/2026/call-for-…

I'd like to share Daqi Lin and I co-authored a chapter in the latest GPU Zen 4 book. We cover the engineering details of implementing ReSTIR GI & PT in UE5's NvRTX branch, adopted in NVIDIA's Zorah project showcased at CES and GDC last year. The book is now available on Amazon.

I often use Inigo's sdBoxFrame SDF for debugging marchers, but found it odd there's no readily available iBoxFrame ray intersector equivalent. So I made one! shadertoy.com/view/7cf3Dj
