For information about the options, seethe section describing the Display form [§4.4.6].• update: Force the display update. Makes sense if the display update is off. This does notnecessarily take care of resizing the display window or using the Forms GUI while the displayupdate is turned off.• update on: Turn display update on.• update off: Turn display update off. By default VMD does the display updates constantly.Sometimes it is beneficial to turn the turn the display updates off. This prevents VMD fromredrawing the scene as a response to every change, thus saving time while doing changes ofrepresentations. See the VMD script library for examples of use.• update status: Return the display update status (on or off).• update ui: Similar to display update, but also forces updates of the GUI forms. TheForms interface is subject to the following behavior: if the display update is set to off andactions (such as, e.g., iconify/deiconify) have been performed to the Forms, the Form windowsdo not get updated by just display update command, whereas display update ui forcesboth updates to happen. Tk does not seem to have this problem, so this option will becomeobsolete after switching to Tk graphics user interface.• resetview: Reset the view.• eyesep value: Set the eye separation to value.• focallength value: Set the focal length to value.• height value: Set the screen height to value.• distance value: Set the screen distance to value.• resize valueX valueY: Set the size of the display window to valueX × valueY. Note that thisoption currently works only with X11 versions of VMD.• reposition valueX valueY: Set the position of the upper-left corner of the display windowto valueX × valueY pixels from the lower-left corner of the screen. Note that this optioncurrently works only with X11 versions of VMD.96
