Dr. Zarebski,

I'm happy to see that everything worked out well for you.

Although I have been interested in the geometric, mechanical, and engineering
aspects of gears for some years, the level that you're operating at is of course
well beyond anything that I've explored in depth.

From a development standpoint, I'm wondering if you ran into any difficulties or
limitations with the present POV-Ray release, and if there were any mathematical
or geometric tools that would have helped you more easily accomplish your task.

And, just out of curiosity, how much more work would be required to fully model
a set of mating gears complete with teeth?  Because that would make a fantastic
animation!

I'm also glad to see that in the course of your inquiries and analyses that you
discovered the previously unknown, or at least unpublished attribute of the
hypoid gears having a contact stripe rather than simply a tangent line. Surely
that will be important for analyzing axle and gear stress, strain, and wear.

Wishing you all the best, and thank you for choosing, using, and mentioning
POV-Ray!
