(ui-panel PANELNAME {on|off} [WINDOW])Do or don’t display the given user-interface panel. Case is ignored in panel names. Current PANELNAMEs are:
main panel
motion controls
appearance controls
camera controls
lighting controls
obscure controls (doesn’t seem to exist any more)
material properties controls
command entry box
geomview credits
By default, the geomview and tools panels appear when
geomview starts. If the optional Window is supplied, a position
clause (e.g. (ui-panel obscure on { position xmin xmax ymin ymax })
sets the panel’s default position. (Only xmin and ymin values are
actually used.) A present but empty Window, e.g. (ui-panel
obscure on {)} causes interactive positioning.
