It's pretty obvious that my programming vocabulary just wasn't sufficient
for that question! Yes, I was talking about the trig functions. Good guess.
I understand the reasons you posted, but I find the extra steps when using
both trig and rotate functions to be unattractive. I guess if my trig were a
little better, I could eliminate the use of rotate and effectively rotate
vertices with translate. Is there anything like a radrotate() function coded
internally into Pov-Ray?
