Meshlets and Mesh Shaders Mesh shaders, introduced back in 2018 as an NVidia Turing and later as an AMD RDNA2 feature, is an evolution of the geometry pipeline which removes a number of fixed function units like the Input A…

I recently started tinkering with mesh shaders in my toy engine to get a feel for what is involved in adding support for them and potential performance improvement opportunities and wrote a blog post detailing my findings. interplayoflight.wordpress.com/2025/05/05/m...

Is-there still time to move Siggraph 2026--2028 conferences to Canada (or Europe...!) ? Are remote technical paper presentations doable ? @acmsiggraph.bsky.social

"Zorah" is a showcase of our work on RTX Mega Geometry, ReSTIR PT, and more in UE5. Really happy with the results and astonished at the incredible assets our art team built.

If you are at GDC, come to our talk "Path Tracing Nanite in Zorah" tomorrow to learn more!

4 weeks to the HPG papers deadline (and 3 to the abstract deadline).
Our call for posters, Hot3D and the student competition are also online and @c0de517e.bsky.social is confirmed as our first keynote speaker.

I'm thrilled to share a new JCGT paper, "GPU Friendly Laplacian Texture Blending." It uses simple image processing and computational photography techniques to smoothly blend/layer textures and materials while preserving local contrast and texture details without ghosting or over-blurring. 1/3

#AltDevBlog

AltDevBlogADay was a very interesting site that hosted posts from industry professionals, covering a wide range of topics. Unfortunately it went down about 10 years ago and is accessible only via web archive web.archive.org/web/20140328.... Definitely worth browsing, many still relevant posts.

Thanks to a lot of colleagues' great work, happy to share Vulkan samples for RTX Mega Geometry. They should run on all RTX GPUs using today's new drivers

WIth the Blackwell Whitepaper we are getting more detial about Mega Geometry - long live the CLAS! I have been looking at the added performance (and fidelity) from its usage in Alan Wake 2 and even on older classes of RTX 2000 hardware it is basically "free performance".
