Here are some tutorials I've written, mostly to save myself some time by just referring people to my tutorials instead of explaining the same things over and over again =)

New tutorials will appear when I find something interesting to write about.

Note: check the 'code' page too for some interesting stuff.

Graphics for Beginners (using SDL3)

2024 - ongoing

Learning about graphics programming, one pixel at a time. Completely revamped version of my old graphics / game programming tutorial, now using SDL3.

This expansive tutorial is suitable for people who are learning programming by themselves, or who know programming but don't know anything about graphics. Programming students may also use it as additional material for programming courses. Bored of those dry programming assignments? Maybe it's time to try something fun.
