Clustering in Vizard 3 beta 1

[Gladsomebeast]

To make the Vizard 3 beta 1 cluster client use the Vizard 3 executables, you must set the VIZARD25_PATH environment variable to point to the Vizard 3 installation directory.

Also, the viz.clusteroffset() commands have been removed. Please replace with the following code:

#old stuff
#viz.clusteroffset(-50, 0, 0) 

#new stuff
# Modify left client for 50 counter-clockwise rotation
viz.pushmask(viz.CLIENT1)
trans = vizmat.Transform()
trans.setEuler( -50, 0, 0 )
viz.MainWindow.setViewOffset( trans )
viz.popmask()
