on the topic of software rendering, im surprised how little gustavo pezzi's lectures get mentioned here on hacker news.

For anyone wondering, Gustavo runs https://pikuma.com/ which has a host of lectures on a variety of topics from PlayStation 1 programming to maths to triangle rasterisation.

Hey! Gustavo here. Thanks for the mention. The 3D software renderer course is still one of my favorites, even though it was one of the first ones I've published. I recently re-recorded the chapter on perspective projection matrix.

Gustavo's lectures are great! I work through his Compiler lectures now and I bought the 3D renderer course too.

Glad to hear that! All the topics are incredibly fun to play around with.
