∟"get_view" and "set_view" on PyMol

This section provides a tutorial on how to inspect nd control viewing parameters, which are used to map the model space to the camera space.

You can use "get_view" and "set_view" commands to inspect and control viewing parameters in PyMol to map the model space to the camera space.

Here is default viewing parameters when you start PyMol:

PyMOL>get_view

### cut below here and paste into script ###
set_view (\
     1.000000000,    0.000000000,    0.000000000,\
     0.000000000,    1.000000000,    0.000000000,\
     0.000000000,    0.000000000,    1.000000000,\
     0.000000000,    0.000000000,  -50.000000000,\
     0.000000000,    0.000000000,    0.000000000,\
    40.000000000,  100.000000000,  -20.000000000 )

Values listed in the above array represent the following viewing parameters:

Transformation Matrix - Value #1 to #9 - Represents rotation from model space to camera space. The default is no rotation:

1.000000000,    0.000000000,    0.000000000
0.000000000,    1.000000000,    0.000000000
0.000000000,    0.000000000,    1.000000000

Origin of Camera Rotation - Value #10 to #12 - Represents the origin of rotation relative to camera in camera space. The default is (0.0, 0.0, -50.0). When you request to turn the camera, it will rotate relative to this given point.

Origin of Model Rotation - Value #13 to #15 - Represents the origin of rotation in model space. The default is (0.0, 0.0, 0.0). When you request to turn the molecule, it will rotate relative to this given point.

Front Clipping Plane - Value #16 - Represents the front clipping plane (also called the Front Slab) distance from the camera. The default is 40.0. So any visualization elements less than 40.0 in the Camera direction will be removed.

Rear Clipping Plane - Value #17 - Represents the rear clipping plane (also called the Back Slab) distance from the camera. The default is 100.0. So any visualization elements greater than 40.0 in the Camera direction will be removed.

Orthoscopic Flag and Field of View - Value #18 - Represents the orthoscopic flag (+/-) and the field of view (if abs(value) > 1). The default is -20.0.

As you may noticed, the output of the "get_view" command is presented in a format ready for the "set_view" command. So you can adjust modify some values and run the command to update the viewing parameters.
