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.

Writing a game the hard way - from scratch using C - Part 2

Sat, 07 Sep 2024 18:54:09 +0000

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.

Learning how to draw things on the Agon Light

Sat, 02 Mar 2024 15:21:29 +0000

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.

Wang Tiles and other ways to tile a plane

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.

Gamedev, music, art and being creative

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…

Setting up MSYS2 and LibSDL2 for graphics programming in Windows

Odroid Go Graphics Programming

Mon, 30 Jul 2018 21:16:30 +0000

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.

Odroid Go Raw Coding

Wed, 25 Jul 2018 20:56:47 +0000

The ODroid GO is a handheld console that sells itself as a device that will run emulators of all your favourite 8bit systems. And it does that job rather well, I spent at least five minutes with mine playing Tetris, and it was a good emulation. Then I installed the Arduino libraries for it, plugged in a USB cable and started trying things out.
