It's always helpful to get someone else's  version of the same material.  So, while the approaches below are different from that of the mild mannered professor, get what you can out of them.
Captain Perspective Reports;
Here are some WWW perspective links I noticed from a cursory reconnaissance:
! John Hagan,British Artist, The best site I've found so far.
! Mung's Perspectives with an Anime flavor
!.Steve Dutch's photos demonstrating Vanishing Points
!.A little bit of rudimentary info
!.  Llama's Perspective Tips- a self-taught artist shares a personal take.
!. Don Jusko's lessons- Good information plus excellent illustrations of aspects of aerial perspective (the color effects of atmosphere on distant images)

If you find some other site as good or better than these, report them to headquarters. (use "Email" below)
