Every frame of a 3D game you’ve ever seen ultimately reduces to pixels written into memory. No matter how fast the GPU or how impressive the graphics, it all comes down to plotting pixels on the screen. Today we’re taking a short look at how triangles get turned into pixels. It seems easy enough, but this is something early software 3D had to do by hand, and something modern GPUs are doing all the time.
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.
This video is my journey through learning how early games drew 3D graphics before 3D APIs and modern GPUs existed. In fact, before old 3D APIs like OpenGL and old GPUs existed, too.
Welcome to the next edition of Gamedev The Hard Way, my attempt at writing a game from scratch for the Agon Light, using nothing but C. This time I create a tilemap system.
In this video, I dive headfirst into coding a tilemap engine for my game — no plan, just pure momentum. Everything seems to go great… until I slam into a brick wall: I have no idea how to actually integrate it into my game.
Welcome to the next edition of Gamedev The Hard Way. This time I’m programming some basic enemy behaviours to test out my game’s entity handling code. Things don’t go to plan however and I discover some quite major problems with the physics and tilemap code.
Part of the fun of making a game from scratch is desinging the systems that run in the background. This time I accidentally try to program a cooperative multitasking operating system. But it’s OK, this is how you do this sort of thing…
After learning about Mode 13h last time, I’ve been digging about in the ancient tomes of wisdom and discovered Mode-X. Let’s make a PC’s VGA card do odd things it was never designed for.

Let’s move into the 1990s and draw some graphics! I’ve got a whole 320x200 pixel screen, 256 colours and direct access to the video card. No APIs, no helper functions. Just me and the video RAM.
