Let’s draw a lit 3D scene without defining any 3D objects. Yeah no it confused me too. I always thought the point of shaders was to make 3D models look fancy.

Today I figured out how to draw a line, and then make it wiggle using some basic maths. (adsbygoogle = window.adsbygoogle || []).

Let’s spend this week learning about GLSL and making fancy images from code. The first one, a nice computationally intensive fractal. (adsbygoogle = window.

Today’s lesson in curing headaches by banging your head on the wall until they stop involves joysticks and mice. This is a bit technical, so ensure your seat back and tray table are in the upright and locked position.

Learning to program is an endurance game full of random side quests, dead ends and frustration. Rather than learning “how to do X”, which is specific, it’s much more useful learning “how to figure out how to do anything at all”.

What better way to wait out the apocalypse than trying to learn a new system. Read how I dug out my ZX Spectrum Next and set about writing C code on it…

How to write GameBoy Advance (GBA) homebrew using modern tools and systems in 2020. Compilers, editors, debugging and more! This isn’t the definitive way of doing things, but it’s a way that seems to work for me.

How a Redcode “CPU” works The CPU is a machine, it follows a basic mechanism to the beat of an external clock. In the case of a Redcode simulator, every tick of the clock causes the CPU to go through what is called the Fetch-Decode-Execute (FDE) cycle.

Sometimes you have to type out almost identical lines of code, and it’s either time consuming or error prone. Here’s how to avoid it all by using some clever Excel techniques.

How to efficiently store and execute many small functions, without using a single if statement or switch construct. Opcodes Redcode contains 17 opcodes which perform standard operations such as copying data, maths and conditional jumps.
