I'm looking for a good book for learning descriptive geometry. I'm not a student of technical drawing, and thus my background in perspective is simply the very basic one most illustrators receive. I can't make head or tail of many of the textbooks I've seen on the subject, and most of them seem to be written for engineers, not artists.
I picked up one good book on the topic, by Wade Meyers, about using descriptive geometry in aviation illustration (which is how I intend to use it), but after reading it, I came to the conclusion that my understanding of perspective may be lacking, since I found it incomprehensible in many ways. The author's knowledge seemed advanced enough that I had difficulty keeping up with him.
So, anyway, I guess I'm looking for a book that will provide me with that "Aha!" moment I am still seeking. Anybody?
