# Math - The Camera Matrix

I’m doing serious progress! Today I managed to get the camera matrix working!

The coolest thing about this is that just a few months ago I would have thought that this was too much math for me to ever be able to understand! Remember that I have written everything from scratch - except for the line render code, which is basically just a `lineTo(x,y)`

function. Even the matrix implementation.

There’s no frustum culling in there yet (except for any z-values behind the camera) so pretty much everything gets drawn all the time.
