tipsy

This resource, along with Mathematics for Computer Graphics by John Vince [1], was truly indispensable when I wrote my own software renderer [2]. This was long before LLMs, so the whole process took me at least a couple months - most of it trying to wrap my head around math behind computer graphics and tracking down C segmentation faults. Fun times. [1]: https://www.amazon.co.uk/Mathematics-Computer-Graphics-John-... [2]: https://github.com/nkanaev/tipsy

It's true that https://github.com/nkanaev/tipsy/blob/master/src/tigr.c is 5500 lines of C but, as far as I can tell, it's just being used to load texture images, draw lines, get double-buffered pixel buffers onto the screen, and get keyboard and mouse events. It wouldn't be difficult to port it to something like https://gitlab.com/kragen/bubbleos/blob/master/yeso. yeso.h yeso-pic.c yeso-xlib.c png.c total 560 lines of C, and all you're missing then is a line-drawing function.
