display

Change various aspects of the graphical display window. For information about the options, see the section describing the Display form.

• update: Force the display update. Makes sense if the display update is off. This does not necessarily take care of resizing the display window or using the Forms GUI while the display update 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 from redrawing the scene as a response to every change, thus saving time while doing changes of representations. 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. The Forms interface is subject to the following behavior: if the display update is set to off and actions (such as, e.g., iconify/deiconify) have been performed to the Forms, the Form windows do not get updated by just display update command, whereas display update ui forces both updates to happen. Tk does not seem to have this problem, so this option will become obsolete 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 $\times$ valueY. Note that this option currently works only with X11 versions of VMD.
• reposition valueX valueY: Set the position of the upper-left corner of the display window to valueX $\times$ valueY pixels from the lower-left corner of the screen. Note that this option currently works only with X11 versions of VMD.
• antialias < on | off >: Turn antialiasing on or off.
• culling < on | off >: Turn backface culling on or off.
• depthcue < on | off >: Turn depth cueing on or off.
• projection < perspective | orthographic >: Set the projection mode to mode.
• rendermode < Normal | AlphaBlend | GLSL >: Set the rendering mode to mode. This parameter allows the use of various OpenGL extensions to implement alpha-blended transparency, or programmable shading for higher quality molecular graphics. The default rendering mode does not enable these features since they significantly alter the rendering and performance characteristics of VMD when they are enabled.

• stereo mode: Set the stereo mode to mode.
• nearclip < set | add > value: Add or set near clipping plane position to it value.
• farclip < set | add > value: Add or set far clipping plane position to value.
• get < eyesep | focallength | height | distance | antialias | depthcue | culling | rendermode | size | stereo | projection | nearclip | farclip >: Return the current value of the requested option.
• get < rendermodes | stereomodes | projections | details >: Return a list of the availalble values for the given options. (See section 4.4.6 and chapter 6 for more information.)
• fps < on | off >: Turn frames-per-second indicator on or off.
