Neural Graphics: Speeding It Up with Wave Intrinsics

This new Slang blog focuses on how you can make use of wave intrinsics-- which you may already be familiar with from traditional compute approaches-- to get more performance out of the familiar 2D Gaussian splatting example.

#slang

Everything is back up and running in my vulkan renderer after implementing automatic shader mapping/binding using the @shader-slang.bsky.social API.

It's now possible to set shader parameters by name instead of using the raw descriptor set/write API.

Starting in 1 hour!

This session is TOMORROW! Please join us for a "getting started" session on the Slang reflection API! Registration info at this link.

I can also clarify the answers to some of the Qs I got in Q&A:
- For issues with non-differentiable operations in gfx, like sampling, Slang provides the ability to define your own diff for specific functions (e.g. to "undo" something like sampling) [1/2]

Getting Started with Slang: Reflections API

Next in the Getting Started with Slang series, we have a webinar on the Reflections API. Join us on July 8th as we explain the underlying mental model for how #Slang reflects shader code.

High-Performance Graphics 2025 High-Performance Graphics 2025 - June 23-25 Copenhagen

Hi Copenhagen! I'm excited to be giving the first of the Hot3D talks tomorrow at HPG. Hope to see some of my fellow graphics nerds there!

highperformancegraphics.org/2025/program...

No fancy engine stuff to show this month, but I've implemented @shader-slang.bsky.social and currently working on automated shader layout + binding. I feel like I'm almost there!

Shaders for Vulkan samples now also available in slang A new shading language enters the ring Unlike other 3D graphics apis, Vulkan did decouple human readable shaders from the api using SPIR-V as an intermediate representation. This makes it possible to ...

Finally finished adding @shader-slang.bsky.social shaders to all my (almost 100) @vulkan.org open source samples and wrote a bit about it here:

tl;dr: I very much enjoyed this :)

Register now for next week's virtual meetup on how to draw your a Gaussian Splat with Slang!

Neural Graphics: From First Principles to Performance

Building on a previous blog on how gradient descent is used to drive Gaussian splatting representations, Working Group Chair, Shannon Woods, explains the changes need to go from that simple example to an implementation that achieves real-time performance.

Neural Graphics in an Afternoon In this article, I’ll show you how to write your first neural graphics program with Slang and SlangPy by walking through our 2D Gaussian Splatting example.

I've finally gotten a chance to put together an in-depth introduction to neural graphics for beginners in Slang using a simplified version of our 2D Gaussian splatting example!
