I do wish I had been more charitable in my youth.
Stolfi's book is basically really good, although it
does have some flaws; unfortunately in my review I concentrated
on the flaws. Now that I'm older and,
if not wiser, at least a little less unkind,
I would write about what's good --- the underlying
ideas, the beautiful formulations of things, the
accessibility of the work, and the important
applications --- and be less picky about details,
and the fact that oriented projective geometry is
really more or less equivalent to "spherical geometry,"
which was known and developed by Riemann. Riemann, of
course, did prove a good deal about the sphere, but Stolfi
tells us things that are computationally important
and worthwhile, but which weren't really even
reasonable questions in Riemann's day. So, far too late,
I now recommend this book to those working in graphics.
