Hi guys. I'm a glaring newbie here when it comes to scripting for Povray, 
but so far I'm really liking it. I've run across a tad bit of a difficult 
problem though. What I am trying to do is figure out an easy way to 
position the text string straight ahead of the camera (as if that was your 
focal point), so that it can easily be read (and changed if necessary). The 
problem is, with the camera angle as such, I'm finding it near about 
impossible to line up the text correctly. Anybody have any ideas on how 
this can be done?

Any suggestions are appreciated...

I think the standard file screen.inc does exactly what you want.

Thanks Kaveh. I'm really trying to get adjusted to this type of programming. 
I'm a perl programmer by trade, and I don't have to think in 3 dimensions 
in that language, so this one's taking a tad longer to get used to :)

I'm a beginner too. It's not often I can contribute to the list, so when
I could, I jumped at the chance!!

Keep at it. It'll be worth it. I am a "TeXie", and discovered povray
recently. They are both languages with limitless possibilities, and both
written in the great spirit of free software.
