Hi, does anybody know about some good exercises on raytracing on the
web? I'm looking for solved exercises that I can go through "by hand",
that is, calculate a couple of rays by myself, by hand, on paper. The
scene should ideally consist of say 2-3 simple bodies (sphere, box). I
want them to be SOLVED, in order to verify my own solution. Yes I have
a couple of books on raytracing but all of them leave something to be
desired in this respect (good, solved exercises). Thanks!

Try looking at this site:
http://www.siggraph.org/education/materials/HyperGraph/raytrace/rtexamp1.htm

It shows you how to calculate rays by hand, but only sphere
intersections are presented. But you could do a lot more if you look
here:
