Hi folks,

in the following script, the stellar constellation
of "Orion" is drawn by 3 spline-objects.As you can
see, the while-loops are absolut identical.

Is it possible to define the spline-coordinates in
a two-dimensional array and let draw the figure by
one extended loop ?

btw.
Sorry for my english (it's not my mother language),
I hope, you can understand what I mean. And please
can you give me a litte example, how I can define
an array..if it's possible ?

Thank You for your help
