get_view returns and optionally prints out the current view information in a format which can be embedded into a command script and can be used in subsequent calls to set_view.
If a log file is currently open, get_view will not write the view matrix to the screen unless the "output" parameter is 2.
This command is very useful for saving the orientation of a scene for later. Authors of molecular movies may find this command very powerful.
cmd.get_view(output=1,quiet=1) my_view= cmd.get_view()
- 0 = output matrix to screen
- 1 = don't output matrix to screen
- 2 = force output to screen even if log file is open
- 3 = return formatted string instead of a list
cmd.get_view(0) # zero option suppresses output (LEGACY approach) cmd.get_view(quiet=1) # suppresses output using PyMOL's normal "quiet" parameter.
Contents of the view matrix
- 0 - 8 = column-major 3x3 matrix which rotates model axes to camera axes
- 9 - 11 = origin of rotation relative to the camera in camera space
- 12 - 14 = origin of rotation in model space
- 15 = front plane distance from the camera
- 16 = rear plane distance from the camera
- 17 = orthoscopic flag (not implemented in older versions)
