Well, that's disappointing. I was hoping to make lines that would  
appear at a given width regardless of the distance to the camera.  
These would be the X, Y and Z origins for a data surface, so  they  
would need to be able to correctly penetrate solid objects.

The tube idea is probably the best bet--though they may disappear  
when I zoom out.
