Pick and [Update REQ 6232]: Geomview

[R.Wardle at sheffield.ac.uk]

Hello,

Thanks for replying to my previous request (REQ 6232) - I have sucessfully
dealt with this now. I have a related question now, concerning the pick
command in gcl. Using Nose with even relatively simple polyhedra I have
difficulty in picking the exact face - sometimes I pick the edge instead
of the face, even when the mouse pointer is nowhere near the edge. Some
faces seem to be almost impossible to pick, too, even though I have
enlarged the Camera window to the full size of my screen. In case this is
a hardware thing, I am using a Sun Sparc 4, Solaris 2.4, 15" monitor (I'm
not sure what the video adapter is, but it is whatever Sun ship with the
Sparc 4). I compiled the program myself.

Is this a recognised problem with Geomview? The picking behaviour as a
whole seems to have an element of randomness about it.


Thanks in advance for your help,
Robin.
