Greetings,
A trip through
povray.text.scene-files
and
povray.binaries.scene-files
should yield an include file called polyhedral.inc. It is a file
the allows you to include (fancy name here} common and tessellated
polyhedral shaped objects. What these shapes are is basically like the
many sided dice you see used in the AD&D games and the tessellated
versions resemble multi faceted stars. You might find a shape in
that file that will resemble a reasonably realistic looking star
and it will allow you to produce it one at a time.
There might be other utilities in the above mentioned groups that
offer a star shaped pattern but I don't recall any off hand. It
wouldn't hurt for you to browse through to see what's available there.
--------
If that does not suit your purposes you could take a look at this
site which offeres a star shaped include file.
http://www.fmi.uni-konstanz.de/~willhalm/graphics/povaddon/index.html
--------
You might also find this site the answer to you design problem.
There are three include files that produce differnt shaped objects.
It has been a while since I have been there so I may be off target
with this one.
http://www.ww-interlink.net/treshall/treshall_povstuff.html
---------
If none of these options get you where you want to be then it's
time to think about making the shape you need yourself. In this
case you will find few utilities that will rival the abilities of
the program called SPatch. It is rapidly becoming the program of
choice for people who need to build a custom shape for Pov to use.
It also has support for other modelling programs so anything you build
with it for Pov can be exported and shared with people that use other
modelling and development software.

-----------
Last and certainly not Least -
There is the last suggestion, and one I am surprised that you have
not tried, and that is creating the object using the wealth of shapes
and procedures already available in Pov itself. There is no way you
will ever become proficient with this program if you do not learn to
use it's features. I won't blow smoke up your --- on this because
Pov is a difficult program to master and the learning curve is both
long and steep.
Given a reasonable effort on your part and a little resolve to give
it time to sink in you will find yourself making more and more
complex scenes each time you use it. The example scenes that were
included with the download were not put there to make pretty pictures
with. Each file demonstrates at least one of the principal features
that pov offers and much can be learned by rendering these files.
Take the time to make changes to see what happens, and then move to
the next one.
This process may not give you the immediate gratification of
building that super scene you want to do right now but it will
make it easier at a later time when you do start the project and
at least you might have a better idea where to start.
Also take the time to go through the tutorials section of the docs
one page at a time. It seems overwhelming if you search for specific
info on a process but it make a lot more sense to you if you actually
perform the steps that are illustrated and evaluate the results for
yourself. After going through them you will find yourself able to
understand the sometimes cryptic instructions for a particular function
to a much greater extent than you can now.
Regards,
