"center", "zoom" and "reset" Commands

This section provides a quick introduction on 'center', 'zoom', and 'reset' commands to quickly adjust viewing parameters on PyMol.

PyMol also provides some commands to quickly adjust viewing parameters without changing molecule atom locations in model space.

"center" Command - Adjusts viewing parameters so that the molecule structure is displayed at the center of the screen.

"center" command is useful, in case the molecule structure has been rotated and/moved out of the display screen and you want to bring it back to the center.

"zoom" Command - Adjusts viewing parameters so that the molecule structure is displayed at the center of the screen and scaled to fit entirely inside the screen.

"zoom" command perform same functions as the "center" command, but it performs one more step to scale the molecule structure view to fit inside the screen.

"reset" Command - Adjusts viewing parameters so that the molecule structure is displayed at the center of the screen, scaled to fit entirely inside the screen, and restored to the default viewing direction.

"reset" command works like the "zoom" command, but it perform one more step to restore the default viewing direction (rotation transformation matrix is restored to the identity matrix).

Note that "center". "zoom" and "reset" commands only changes viewing parameters. They do not change molecule atom locations in the model space.
