Re: obj graphics fly-thru help
And yes, I have looked at the IDL demo program flythru.pro. This
interface isn't close to what I would call a flythru. Try it and you'll
see what I mean.
I am starting to think that the problem is more complex than I first
Does anybody know if this is even possible in IDL?
