#Graphics

These are some notes on how to manually draw triangles in code. Possibly useful if you’re trying to write your own software renderer, or are just curious how it works.

Join me on a journey as I attempt to write a game for my Agon Light using nothing but raw C programming. In this second episode I figure out how to make a very basic 2D rigid body physics system work.

I’ve been having a bit of a play around with my Agon Light, trying to come up with some ideas for a future video. I’ve discovered it has quite a nice 320×240 64 colour video mode that has just enough pixels to be interesting.

Understand the concept of tiling a plane by arranging regular tiles in a systematic manner, creating visually pleasing patterns. Additionally, get introduced to Wang tiles, a fascinating method that employs specific rules for tile placement, resulting in captivating, non-repetitive designs.

I am not a creative person, and I’d quite like to change this. There’s a bunch of creative skills I’ve never put the effort into improving and I think I might have some ways to overcome this. Let’s have a look…

I’m starting a graphics based project, and decided to use SDL2 in Windows. This meant setting up a development environment. Here’s some notes on how I set up MSYS2, VS Code and LibSDL2.

Making a microcontroller produce graphics is very similar to making an old 8 or 16 bit computer draw images. They both have small screens, not much RAM and not enough CPU power to draw all the screen all the time.
