I have used Blender for some years now and I recently began to think about buying a 3dconnexion Space Navigator.

I read that Blender and the Space Navigator worked under Linux and managed to borrow a Space Navigator from work over this long weekend.

I downloaded the 32bit drivers (3DxWare for Linux (i386)) from http://www.3dconnexion.com/service/drivers.html as well as the “Blender plug-in for Linux i386 (beta)“

Installing the Space Navigator driver

I extracted the 3dxware-linux-v1-4-3.i386.tar.gz file to /tmp/3d/

tar -xvzf 3dxware-linux-v1-4-3.i386.tar.gz -C /tmp/3d/
cd /tmp/3d/
sudo ./install-3dxunix.sh

I then recieved an error saying libXm.so.3 was missing.

/etc/3DxWare/daemon/3dxsrv: error while loading shared libraries: libXm.so.3: cannot open shared object file: No such file or directory

I pressed CTRL-C to abort the script.

After a little checking I found that I have libXm.so.4 but not 3, so I created a symbolic link from libXm 4 to 3.

sudo ln -s /usr/lib/libXm.so /usr/lib/libXm.so.3

I then re-ran the install script again.

This time it all worked.  I did not configure it to auto start though.

Now I simply started the driver via

sudo /etc/3DxWare/daemon/3dxsrv -d usb

and was greeted by the blue lights on the Space Navigator and the messages

3DxWareUNIX = V1.4.3
Device      = SpaceNavigator
Firmware    = V3.17

there was also a minimised window called 3DxWare 1.4.3, which appears the be the settings dialog (like the Windows Control Panel control)

I then ran the xcube example from /tmp/3d/ and the space navigator worked great.  I changed a few settings as I prefer pressing and pulling to be zoom in and out.

Installing the Blender plugin

I was a little surprised by this, as the forums said I should have a ~/.blender/ directory and I didnt.

I decided that creating the directory couldn’t cause any problems so I created a directory

mkdir -p ~/.blender/plugins/

and copied the 3DxNdofBlender.plug file into it.  The new NDOF icons appeared at the bottom of the viewport.  See http://www.blender.org/development/release-logs/blender-246/ndof-support/

I have been playing with Blender again and I spent a few days trying to render my Lego Camper Van.

I managed to create this.

Well after lots of searching I found a very good tutorial for blender. Its a tutorial on how to do hair with the new particle system.

Its called Tutorial, Fur with new particles and its over at cgtalk.com

See http://forums.cgsociety.org/showthread.php?t=303334

Here is the results I managed to get after about 1 hr of tweaking.

One warning, when I turned on GI with yafray this render took ages. I expect I got something wrong though.

I also found this tutorial. It appears to be for an old version of Blender, but it explains how to get the radiosity to work in Blender.

The tutorial is available at http://blenderman.free.fr/tut/radiosity/uk/

I managed to get this
