       3dmodv - View an Imod model.

       3dmodv  [options]  model_files...

       3dmodv is used to view models drawn with 3dmod.  The main 3dmodv window
       is the same as the "Model View" window available in the program 3dmod.
       When run from the command line, 3dmodv can read and save models through
       the File menu.  Multiple models can be loaded and manipulated indepen-
       dently, either by putting their names on the command line or by loading
       them one after another through the File menu.  The command line options
       and hot keys are given below.  See the Help menu of the Model View win-
       dow for information on mouse actions and menu entries; see the help
       pages for individual dialogs for full details on the controls in each

       3dmodv can accept standard Qt options in addition to the options
       described below.

       -f     Open model view window to maximum size supported by graphics.

       -b color
              Select the color that 3dmodv uses as the rendering background.
              The color is a standard Qt color name.

       -s width,height
              Set the initial size of the model view area of the window.  This
              is useful if you want to take snapshots at a specific size.

       -E keys
              Open the windows specified by the key letters, which are the
              same as the hot keys for opening windows (m, O, C, L, B, M, N,
              V, I, U, R), plus D for depth cue and S for stereo.

       -L     Listen for messages on standard input instead of the clipboard,
              and do not put 3dmodv in the background automatically.

       -D     Run in debug mode with diagnostic output and without becoming a
              background process.

   Hot key shortcuts for 3dmodv.
       - =    Decrease/increase zoom with small steps.

       Keypad +
              Increase zoom by small steps

       Arrow Keys, Page Up, Page Down
              Translate model, or current clipping plane if Ctrl is held down,
              in X, Y, and Z, or current point if Ctrl and Shift are held down
              and the current point is in a scattered point object.

              Delete the current point if it is in a scattered point object
              and 3dmod is in model mode.

       Numeric Keypad
              Rotate model, or current clipping plane if Ctrl key is held
                 The 4 and 6 keys rotate about the Y view axis.
                 The 8 and 2 keys rotate about the X view axis.

       Substitute Keypad
              The keys centered on U will also rotate the model or clipping
                 The y and i keys rotate about the Y view axis (but Ctrl-U
              instead of
                    Ctrl-Y rotates the clipping plane).
                 The 7 and j keys rotate about the X view axis.
