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.

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.

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.

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".
