Apologies for the audio. I had already tried and failed to record this 4 times, and by this point I gave up. Next update will certainly have fixed audio.
This is a pure Haskell CPU renderer I’ve been working on since I started it in March 2026 in free time. It is currently tiled-deferred but I would like to build in the capability to forward render with it also so transparancies can be added in a separate pass. A lot of work will go into making it faster: ideally, I want to know how fast it can go with just pure Haskell.
I’m putting this here as a few people were interested in it a Zurihac and I’m hoping that there may be some info in the repo/video that may help someone solve a similar problem 
.
You can clone/fork it from GitHub: GitHub - tobz619/tobz-renderer: A pure Haskell CPU renderer with the goal of getting as fast as possible by learning and applying good graphics and memory techniques. · GitHub .
