Just a general question:
Which is actually better, in terms of resources used by povray:
a) to have a smaller scaled object and then scale it up
b) have a larger scaled object and not need to 'scale' it anymore
c) having a small scaled object and just making your scene small scaled?
As an example, if I have a 255 foot tower, am I better off
a) using .1 = 1 foot and then using scale 10 to being it up to 1 unit = 1
foot
b) just using 1unit = 1 foot everywhere
c) just using .1 unit - 1 foot everywhere
or does it matter at all?
I realize this may be a silly question, but I was just curious whether any
of these possibilities makes any difference to Povray.
Thanks,
Darcy

Well, one option is to use an include file and define some units.
You could then do something like
sphere{ <0,0,0> (1 * foot) }
sphere{ <0,0,0> (.5 * inch) }
And then try declaring different values for 'foot' and 'inch' and test
what happens.
BTW, that's one thing we are recommending for the IMP.

Hello Darcy,
I don't think it matters on PovRay's part: A number is a number,
is a number.. That is if povray has to scale it has to do it, and
the time used is so and so.
But for me I choose some scale that is convinient for me.
Depending on the situation, I use mm, m or some arbitrary scale
that produce the picture I want,
