TITLE: Textbook for Projective Geometry
QUESTION [14 upvotes]: So while not actually a specific problem I'm struggling with, I was hoping for some of your insight!  For a course, I'm currently reading Stillwell's Four Pillars of Geometry.  While it does a nice job of motivating the theory, I find it a little sparse with regard to challenging/engaging problems.  Any suggestions as to where I can turn to find a nice supplementary text on projective/hyperbolic geometry?

REPLY [4 votes]: If you, or anybody else, needs the theoretical background behind projective geometry for Computer Vision, I found these two books to be great: (1) Multiple View Geometry in Computer Vision by Richard Hartley et al., and (2) An Invitation to 3-D Vision by Yi Ma et al.
