I'm not sure linear algebra is the best way to get into 3D graphics. I'd suggest, starting with old fashioned 3D renderers such as ray casters. https://en.wikipedia.org/wiki/Ray_casting https://en.wikipedia.org/wiki/Ray_casting Of course it has more to do with raytracing than with 3D projections (which is most often used for real time 3D rendering). If you want to learn about 3D projections, first you should understand what linear algebra has to do with projecting a 3D model on a 2D screen. This is probably a good start. https://en.wikipedia.org/wiki/3D_projection https://en.wikipedia.org/wiki/3D_projection And then, learning about matrix multiplications makes sense.
