I added Chimera support for the Space Navigator 6-degree-of-freedom
input device (costs only $60) for Mac and Windows.
I expect it will work with other 3dconnexion devices such as your Space
Explorer. If you download the current Chimera daily build
for Windows or Mac OS and have the 3dconnexion driver installed, the
device will move and rotate Chimera models.
I have only two button assignments: Button1 or Fit centers the models
and scales them to fit in the window, Button2 toggles a mode allowing
simultaneous rotation and translation (default off is called "dominant"
mode by 3dconnexion). The Windows Control Panel or Mac OS System
Preferences lets you change the assignments of the device buttons. You
may not have any assigned to be "Button2" unless you change those settings.
There are also a few keyboard shortcuts that change modes. Shortcuts
or Accelerators are turned on with menu entry Tools / General Controls /
Accelerators On. Shortcut "nf" turns on "fly through" mode. Instead of
the device behaving as if you are holding the models it is used to
control the viewer position (ie. pushing forward flies you forward
rather than pushing the models away from you). It is hard to control --
needs more programming work. Shortcut "na" allows the device to move
both inactive (frozen) and active models. This can be useful if you are
docking a molecule into a map with the mouse and changing view points of
both molecule and map using the space navigator. Shortcut "nd" toggles
translate/rotate only mode (i.e. "dominant" mode). I just added that
today so it won't be in Chimera until tonight's builds.
