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.
That's right. :-)
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.
