I'm trying to create a function who creates light ball,like this one,out of dimensions and color.

When I try this code which should just create a line in the middle it crashes,the questions are why it crashes and if there's a way to archieve what I mentioned above. Thanks for your attention.

Edit: the program no longer crash.
