I want to learn perspective formally for art. I understand that this comes under Projective Geometry, but every book I found was about studying abstract projective spaces, assuming prerequisite knowledge of algebraic geometry. I am not sure if this will help me. I would like to have something that focuses on straight rule and compass constructions on figuring out how to put cubes, spheres and other simple forms and their cast shadows in 3d space.
In essence, I want to learn the formal theory of what's covered by this YouTube channel (with the proofs for why they are true).
P.S. I am familiar with most of undergraduate level math and grad level analysis.
