Looking for a basic @vulkan.org #Vulkan descriptor heap example? I've got you covered: github.com/SaschaWillem...

Cornell box rendered by ray tracing using the pinhole camera model and the camera model with radial distortion - a comparison.

Want to build your own ray tracer or path tracer on AMD GPUs? Our #Raytracing using #HIP paper covers:

🎇 The essential math
🎇 Camera setup, intersections, NEE, BVH
🎇 How to accelerate everything with HIPRT

I recently read this paper. Interesting idea to use infrared to decompose the lighting terms.

I just released my video about the engine (and game) I've been working on.

The engine is based on dynamic SDFs, and the video describes how it works and what it makes possible.

This is my first YouTube video and it took forever - please repost!

Hello everyone!

I am available for work (full time position/internship) anywhere in the world with priority going to the EU, starting June 2026. 🧵

No Graphics API — Sebastian Aaltonen Graphics APIs and shader languages have significantly increased in complexity over the past decade. It’s time to start discussing how to strip down the abstractions to simplify development, improve pe...

I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

What a awesome read!!!!

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.

Experimenting with this look for the fractals.

It's GDS Prague Game Jam!

Game Jam progress :)))

C++ code that emits an OBJ file filled with points from voxel edge/SDF intersections.

A collection of vertices in OBJ plaintext format.

A sphere of vertices in Blender.

Dirty gamedev secret: sometimes instead of building proper debug visualizations I just dump the information to OBJ and use Blender to visualize it 😅

But now at least I know my SDF dual contouring is working

I saw some really interesting talks today!

Ive learned a ton about how virtual lights can improve indoor rendering and what the pitfalls are.

This is a great article about ReGIR / World-Space ReSTIR with nice improvements by Tom Clabault:

Here I try to explain it in simple terms, while giving some historical context as well.
There is also a quick RTAO implementation with the worst denoise ever here:

feedback is more than welcome!

Bonus post to end the week: If you are a graphics programmer do yourself a favor and get a MIDI board. It makes the work way more tactile and fun. Full props to Matt and @aaronmjacobs.com for getting me on the MIDI train. :)

I've released a simple RTAO implementation, written for the DevGames2025 conference.
a poor-man's RTAO, showing how much the real problem is denoising.
I wanted to write the simplest RT as an introduction to it.

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:

www.saschawillems.de/blog/2025/06...

tl;dr: I very much enjoyed this :)

I'll be talking about SDFs and creative workflows tomorrow, hosted by the SIGGRPAH San Francisco Chapter - please sing up here before they close registration tomorrow noon.
