Each riser is a circular segment--the difference of a donut (difference of two
cylinders) and a couple rectangles oriented to result in a pie segment.

Which is how I did it in POV-Ray :)

The handrail was a pain to do in POV-Ray too, since I couldn't find an easy way
to do a helix. I didn't make the inside rail because my helix approximation
for the outer rail fell apart at such a steep angle. Lots of trial and error
is much easier to do in POV-Ray than in DAT format...especially original DAT
with none of the LDLite commands...

| (...) Duh. Of course. Doesn't POV-Ray have some kind of sweep/turn function, so you could take a rectangle (one side of pie slice) and turn it through a specified angle to generate the riser? Steve (24 years ago, 17-Oct-00, to lugnet.off-topic.fun)
