What I don't get is why nearly all resources on 3D graphics assume the reader is familiar with matrices and linear algebra. For those who don't speak that language, what you're doing is plotting numbers into a magic box, doing a magic multiply, and hey presto, we got 3D! Magic. Meanwhile a teenager could easily get an intuitive grasp of 3D graphics if you just explained how translation is nothing besides addition, an…

Speaking of short tutorials on linear algebra, you should check out this one I wrote last year. It's more of a "prepare for an exam" document, but it gets to the core idea of matrix-vector product serving as a way to "implement" linear transformations: https://minireference.com/static/tutorials/linear_algebra_in... I'm personally fine with using the computer as a "magic box" to do all the calculations, but it's impor…
