Ke-Sen Huang has a large batch of SIGGRAPH Asia papers today:
www.realtimerendering.com/kesen/siga20...
Among them: "ReSTIR PG: Path Guiding with Spatiotemporally Resampled Paths" by Zeng et al., which describes a *real-time* framework combining ReSTIR PT and path guiding.

Newly released VK_EXT_present_timing extension combines two fundamental features:

-The ability to receive timing feedback about previous presentation requests
-The ability to explicitly specify a target presentation time for each request

Upsampling via Multisampling Can we use multisampling effectively for upsampling? This has been a question in the back of my mind for give or take 10+ years.

Using Neural Networks for Geometric Representation Explore how Neural Intersection Functions (NIF) and the enhanced LSNIF are poised to reshape ray tracing by replacing traditional BVH traversal with efficient, GPU-friendly neural networks for acceler...

#Raytracing BVH traversal struggles on GPUs due to irregular control flow.

🎇 Our Locally-Subdivided Neural Intersection Function (LSNIF) is an ML-based alternative for optimized #rendering.

For me, the fun and joy of making art comes not from the result but from the process of learning/iterating. I don't find that in prompting AI; I suppose some people do and good for them, but for me making art is only fun if I actually go through the process of doing it myself.

This new sample demonstrates how to use the VK_KHR_dynamic_rendering_local_read extension in conjunction with the VK_KHR_dynamic_rendering extension. This combination can replace core render and subpasses.

Interesting blog post about the 2 year process of rewriting fish-shell in #Rust. Gradually replacing C++ components with Rust versions and using various techniques to maintain interoperability while the rewrite was underway.

Added the ability to watch the rays in my path tracer bounce around as an animation. I'm excited about this more from an education POV, I think it helps explain how path tracing works far more easily than I could describe in words

New blog post: Relativistic Quaternions
I briefly discuss what quaternions and dual quaternions must become in spacetime in order to represent physically meaningful motions.

Refracting Pixels | Froyok - Léna Piquet What started this article is that I wanted to support refraction in my realtime game engine (which you can learn more about here). I didn't find a lot of clear documentation on the subject, so I went ...

I wrote a new article, this time exploring a bit how some games handle refraction.
I discovered quite a few interesting tricks !

GPU Zen 3 is out!

I want to draw attention to the 96(!) page article I was a small part of detailing all the work from tooth-to-tail we put into making ray tracing a reality in Cyberpunk 2077. It is exhaustive and should be a reference for anyone looking to make RTX a reality in their own engines.
