Small side project: Implemented radiance cascades in Unity using the SRP Render Graph system. An awesome method for real-time 2D global illumination!

Working in gaming can sometimes feel a bit intangible. All your work is purely digital. That's why I thoroughly enjoyed developing this custom peripheral for surgical training.

Combined with making the games you can use them in, the past two years really have been a blast!

Just learned about the 1€ filter: jaantollander.com/post/noise-f...

It's an easy method to filter noisy input data. More flexible than the exponential moving average that everyone seems to use in game dev, in that it provides a better balance between SNR and lag.

This article explains how to implement the 1€ Filter for filtering noisy real-time signals and provides a simple Python implementation of the algorithm.

Friends, I am looking for new opportunities as a Game Producer, preferably remote!

Please let me know if you know of any available roles, or freelance projects that need a producer/PM. Website with all relevant links is in my bio (and is my handle).

Reposts are incredibly appreciated!

I really love the vector monitor aesthetic. Did a little experiment with a polygonal wireframe renderer + some procedural greeble generation. Became nice prototype for an endless trench-run game.

Might make a rogue-lite out of this one day...

Recently found out this self-published novel series. Even though it came highly recommended, I expected a lot of cringy/fanfiction type of writing. So far I'm really enjoying it! Sure, it's not high literature, but it is stupid fun.

Excited to start this year's Advent of Code tomorrow (adventofcode.com/2024/about).

Last year I tried completing the puzzles in x86 assembly. That, in combination with limited free time, meant I didn't get past day 2. So I'm switching to Python for this year xD
