I'd like to share @DaqiLin 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.

🌲Introducing our paper A generalizable light transport 3D embedding for Global Illumination https://t.co/Ui4GOmw8RH.

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 scene.

Building on the analogy of light transport operator and Attention, our fully scalable model learns a generalizable light transport 3D embedding that captures global illumination.
It takes as input the 3D scene assets—geometry, materials, and lighting represented as a point cloud—and encodes the complex light interaction into a 3D latent space, with codes anchored at the sampled scene points.

Remarkably, the model is independent of both viewpoint and resolution, enabling view-consistent rendering across diverse scenes. (See teaser and attention figure.)

(Our team work: with my mentor Marco @marcosalvi, labmates Mukund @mukundvermar, Cheng, NV folks Bart @BartWronsk, Lifan @winmad4869, and Tzu-Mao @tzumaoli & Ravi.)

We finally get to share our neural materials research.

We created custom highly-realistic reference materials, we invented new neural models, and we built new graphics systems.

End result is these neural materials run in a real-time path tracer.

Excited to share our new ReSTIR work! Our Area ReSTIR fixes regions where reuse breaks. It's simple to be implemented on ReSTIR DI/GI/PT. Check the paper and @SongZhang__ 's code for details.

[Song Zhang @SongZhang__]

Thrilled to share our SIGGRAPH 2024 paper, "Area ReSTIR: Resampling for Real-Time Defocus and Antialiasing"! We've expanded ReSTIR to reduce noise in various scenarios, from large bokeh to intricate high-frequency details.
