3D Mouse

From ArchWiki

From Wikipedia:3d mouse#3D mice:

Also known as bats, flying mice, or wands, these devices generally function through ultrasound and provide at least three degrees of freedom. Probably the best known example would be 3DConnexion/Logitech's SpaceMouse from the early 1990s.

Note: The following instructions have been tested and proven to work on the most basic model (Space Navigator).

Proprietary drivers

Tango-inaccurate.pngThe factual accuracy of this article or section is disputed.Tango-inaccurate.png

Reason: Symlinking shared library files and running random strcpy code as root is incredibly hacky and potentially dangerous. (Discuss in Talk:3D Mouse)

1. Plug your 3D mouse into your USB port. Use lsusb to check if it was recognised

$ lsusb
Bus 003 Device 002: ID 046d:c626 Logitech, Inc. 3Dconnexion Space Navigator 3D Mouse

2. Install openmotif.

3. Symlink libXm.so.4 to libXm.so.3

# ln -s /usr/lib/libXm.so.4 /usr/lib/libXm.so.3

4. The driver has some problems to get the username from /var/run/utmp and will output a "failed to get user" error.

To fix this problem compile the following program. It appends the given username to /var/run/utmp in such a way that the driver can read it.

5. Download the linux drivers to /tmp from here: https://www.3dconnexion.com/service/drivers.html

6. Unpack the install script and run it

$ tar xfz 3dxware-linux-v1-5-2.i386.tar.gz install-3dxunix.sh
# ./install-3dxunix.sh

This installs 3DxWareUnix V1.5.2 on this machine. Continue? (y/n) [y]

  1.  HP-UX
  2.  Solaris
  3.  AIX 5

Do you want 3DxWareUnix being started with every login (from the /etc/inittab)? (y/n) [y]

Please start the driver manually. [/etc/3DxWare/daemon/3dxsrv -d <port>]

    For testing purposes you can find the demos
                      xcube and xvalues at /tmp

NOTE: I chose not to run the driver everytime I login.

7. You can run the driver manually by calling it like this (for USB version):

# /etc/3DxWare/daemon/3dxsrv -d USB

8. You should now have a working 3D mouse in Arch Linux! You can test it by extracting the demos from the driver archive.

$ tar xfz 3dxware-linux-v1-5-2.i386.tar.gz xcube
$ ./xcube

Open source drivers

There exists also an open source driver for 3Dconnexion devices maintained by the spacenav project. From the short list of softwares that supports spacenavd we can cite:

  • Blender
  • Freecad
  • OpenSCAD

For it to work three things must be fulfilled

  1. The device must be recognized by the kernel as input device
  2. The spacenavd daemon must be running
  3. The application must be compiled with spacenav support. (community/blender should be)

The first requirement should be fulfilled automatically after plugging in the device. It can be checked by looking if the device is listed in /proc/bus/input/devices e.g. by

$ grep 3Dconnexion /proc/bus/input/devices
N: Name="3Dconnexion SpaceNavigator"

For the second point install libspnav and spacenavdAUR (or spacenav-plusAUR if you need support for older serial mice) from AUR. For testing it is a good idea to start the daemon on foreground mode. The output should look similar to this:

# spacenavd -v -d
Spacenav daemon 0.5
Device detection, parsing /proc/bus/input/devices
using device: /dev/input/event21
device name: 3Dconnexion SpaceNavigator
trying to open X11 display ":0"

If it works you can simply shut down the daemon by hitting CTRL-C and run it using the following service to start the daemon (should come with spacenavd).

Description=Userspace Daemon of the spacenav driver.



Now everything is up and running and every supported application should be able to use the 3D Mouse.

Blender with spacenav support

The blender package in the community repository is now compiled with spacenav support by default.

However, if you wish to rebuild Blender with spacenav support manually, you can install libspnav first and then rebuild blender from ABS. It will automatically build with NDOF(=spacenav) support.

Now you can fire up blender and test your 3D Mouse.

$ blender
ndof: using SpaceNavigator
