That's a good reminder to distinguish AR from VR in that Computer Vision is greatly involved in the former.

>Are you looking for books that teaches advanced graphics?

That would be helpful (I have a few already on a wish list), but I'm more interested in resources for job openings or companies that are involved heavily in VR.

I already have working 3D math knowledge, having used matrices and linear algebra in my last job, integrated with procedural generated geometry, as well as implement some lighting functions in pixel shaders.

So for now I want to focus on the jobs I can step into.

If I were to take online courses, Computer Vision will probably be the subject I would most benefit from.
