Got them. Thanks. A little light reading for laundry day, tomorrow.

I may still have some old POVray DOS floppies from the 1980's when I had
to order share ware by mail. I never had a machine fast enough to do
anything useful with them. I'm looking forward to developing some photo
realistic images for a project. I'll be happy to share anything I learn.

That is the way I have usually learned programming related stuff. I look
at what someone else did in a book, and then adapt it to what I want to
do. Along the way, I sometimes learn something useful, too.

Kind of like building solid models in wire frame to get the geometry
right before running the rendering engine on one of the old CAD systems
I used to use.

My initial interest is in photo realistic stills. But one day I might
want to do some animations.
I'm looking forward to the journey.
