Subject: view/zoom bug?

It seems buglike. Is it a bug? here is a reproducible example

open 2gbp
open 2fw0
mm #1 to #2
view #1
zoom 2

If you put "clip false" in the view command, the structures don't disappear upon zoom.

The "view #1" command sets the near and far clip planes, for example to be 30 Angstroms and 50 Angstroms in front of the camera where the molecule center is 40 Angstroms away. Then "zoom 2" moves the camera twice as close so that the model is now 20 Angstroms away so that it appears twice as large. But then it is in front of the near clip plane which remains at 30 Angstroms.

It would be nicer if the zoom command adjusted the near/far clip positions, e.g. "zoom 2" would move them to be twice as close to the camera. When you zoom with the mouse the near/far clip planes get moved automatically.

Fixed.

Made zoom command move near/far clip planes if they are enabled.
