[Chimera-users] suggestion: reset list

Hi Matt,

  There is a Python script camerapositons.py on the Chimera scripts web page that does this.

	http://plato.cgl.ucsf.edu/trac/chimera/wiki/Scripts

It only reports name, camera position, and field of view.  If you want other parameters you could modify that Python script.  The camera parameters are defined in the following C++ header.

http://plato.cgl.ucsf.edu/trac/chimera/browser/trunk/libs/_chimera/Camera.h

For instance, you'll see the method "fieldOfView()" there and that is used in the Python script as cam.fieldOfView.

  The workings of the Chimera camera are pretty arcane.  It always points in the negative z direction.  It move along the z axis to control depth, and along x and y to control center of view.  The models rotate to handle scene rotations.

	Tom
