The fact that the one game made by an explicitly communist co-op game studio now has three successor studios making a self-proclaimed sequel to it, and dispute the legitimacy of the other two is, of course, the most communist outcome possible.

Roughly a 5 years old paper by now, but seems awfully relevant still. By a former student of @cemyuksel.com, who I believe is at Nvidia now.

It does mean we could design games (even action ones) in a way that works with limiting the number of rows redrawn - allowing us to target a stable 60fps with good engineering.

At some point the screen can't keep up. This is what the screen on device looks like with the noise at 12 rows high.

The changes are so rapid the screen can't change the pixels quickly enough - which... I mean we don't need 1000fps ... right? 😢

Playdate refresh rate is limited based on how many rows you update on the screen.

Full screen refresh (240 rows) you get 50 frames per second (more like 51-52 without mirror running like in my video).

You can get higher framerates by updating less rows.

This is not a joke! I decided to make a drone and a cleaning mechanic after watching this movie with Chevy Chase. I watched Modern Problems a long time ago, and 2 weeks ago, after watching it again, I realized that I need a dustpan cleaner. This is how sick my brain is #gamedev

I am excited to share this new single-header C library I have been working on for a while now: vecmath.h, a comprehensive vector/matrix math library for graphics/games/3d.
It allows you to write vector math code in C that looks like this:

Wrote a little shader to visualize De Castlejau's Algorithm for constructing a Quadratic Bezier Curve after watching @freya.bsky.social presentation from 2021 "The Beauty of BΓ©zier Curves"

You should watch it, its inspiring and great and pretty. youtu.be/aVwxzDHniEw

Finally I decided to learn more about lighting and start adjusting it in the game. Logic has never let me down, I asked Google what are the different types of exposure and light powers, then temperature... I tried it in Unreal Engine. It's unbelievable. Standardization! #gamedev #UnrealEngine
