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:

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.

Left. The dominant axis is x. We first translate the ray along its direction vector such that the transformed ray’s origin o coincides with the subspace spanned by the other, non-dominant axes (only y in this 2D-example). Scaling the direction vector by 1/dx the x-component of the transformed ray’s direction d becomes 1. Now the intersection ray parameter with the near and far plane along the x-axis directly corresponds to the bounding box coordinates bminX and bmaxX without any further computations required

Axis-Normalized Ray-Box Intersection
"By transforming the ray we eliminate the need for one third of the traditional bounding-slab tests and achieve a speed enhancement of approximately 13.8% or 10.9%"

part of my job today was helping someone put sticky notes on themselves. we are so back

Congrats!!!!! really deserved!

Couldn't agree more

Wait.... there was a cooking guide on the DS?

Just did my bi weekly recomile of UE5-Main and we have a new Viewport UI! woah

Looking good!

So, I have about a 100GB of god of war ragnarok captures. Let's to that livepost study shall we ? I'm going too start with a cine character shot. To see how the frame is build. W'll check some specific effects (like snow) later.

I use it to keep track of concepts that i learn when working on my Bachler thesis.

You can just use it like a general note app or go crazy with it. i think its that hard to start using it.

First time implementing something from a Research Paper.

At first it looked really scary but after rereading the paper a few times i got it.

Here is my implementation of GTAO (Ground Truth Ambient Occlusion)

I had a blast doing this and even got more interested in everything around radiology.

SSAO

SSAO + Color

Another day another SSAO, But this time in the Forge Framework.

Its been pretty fun to learn the Forge framework and what the differences are to my own "framework".

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 !

Work in progress on our group project game.
Its going pretty good!
