It is. I frequently forget at first the interoperability of splines and
prisms.
Way more elegant than my suggestion.
A few points:
Directly:
1. Does the code as pasted give the desired result? I made an array of all 18
points and used those in a spline, and I got a larger sphere (r = 3.701) that
touches the outer part of the prism.
Only tangentially related:
2. It would be nice for prism{} to accept an array as an argument directly, and
for it to select the x, z coordinates from a vector with greater than 2 elements
/ components.
With regard to names / syntax (recent commentary/questions about #declare /
#undef, and rewriting things in povr has my mind in that mode):
Why do we have # before things like for, etc. and not others?
dimension_size is "long" and I find awkward to remember. array_size, size_of,
or something like that would be a nice alternative.
Inside of various declarations, I often add an extra comma, so if I were coding
Jerome's scene, I will frequently write
sphere {0, LOWEST, pigment {color red 1 }}
^
and POV-Ray does not like that.
I believe there are a few other places where extra commas generate an error that
prevents rendering - I will try to be mindful of those and point them out.
