Does anyone know of an already existing tutorial about
creating spiral shapes?

Thanks

There was a thread called 3D match some time ago in .general, where a
spiral was created..

An easier way to do it is like this: (untested)

#declare rounds = 15;
#declare radii = 10;
#declare O = sphere { <0,0,0>,0.5 pigment { Yellow }}
#declare MaxY = 50;
#declare Num = 1500;
#declare iNum = 1/Num;
#declare iNum360 = iNum*360;
#declare iNumMaxY = iNum*MaxY;
#declare N=Num;
#while(N>0)
  object {O translate <radii,N*iNumMaxY,0> rotate <0,N*iNum360,0> }
  #declare N = N-1;
#end

This should do a spiral between 0 and MaxY, evenly spread with Num
objects. 
I also have a spiral like #macro in the fireworks include file. The one
to make the trails of the fireworks.

There is a new group on the server called announce.frequently.asked.questions
that I posted a pov tutorials link faq to last week. If there has been a
tutorial written on the subject you will find a link for it there.

Guys!
What do you take me for?!

I KNOW how spirals should be made, what I asked was if
anyone knew of an already existing tutorial about it, since
I'm thinking about making one myself...

Thanks.... I guess...?

Julius

I think my reply was if anything accurate and in context with the
requested information. If time had permitted I would have provided
a more a definitive answer. As I either did not know at that time,
or had no time to find out, I at least narrowed the field of search
for you by a very wide margin.

At least "I" didn't just provide an example like one other person did.

:)

Sorry Ken, my answer was aimed at Spider's message... I
guessed it missed its target.
I took a look at your list (nice work by the way) and
couldn't find anyone really covering the subject, so I guess
I'll have an addition to your list in a moment (or a bit
longer).

Thanks again

Julius

That's not necessary... I wasn't offended, just surprised

I think I got the point, and I really hope I didn't offend you. That was
not my intention.
