Thanks for your comment and apologies for the lateness of my reply – I’ve been neglecting this blog. I’m afraid I don’t have any recommendations for you on either count, although my understanding of homogeneous coordinates is that the justification is more engineering than mathematics: they make the implementation computationally simpler because every movement is multiplication (and not only that, multiplication by a matrix with a large number of zeroes). Best of luck!

I am a retired EE ,77 yrs old, that has become interested in matrices, and
through these studies have encountered Computer Graphics using matrices.

QUESTIONS:
1. Can you suggest an inexpensive textbook that introduces Computer Graphics <used, less than $20), with a level that discusses homogeneous coordinates ?

2. Which free Internet net site might I use to learn Computer Graphics?
I especially want to learn about the mathematical justification for using homogeneous coordinates

Thank you,
