Cluster

1 Attachment(s)

I use one main-computer and three cluster computers.
Three screens are connected with the three computers.

UpperLeftWindow = viz.addWindow(pos=(0,1.0),size=(0.2,0.4))
UpperLeftWindow.visible(0,viz.SCREEN)
BirdView = viz.addView()
#Attach the bird's eye view to the upper left window
UpperLeftWindow.setView(BirdView)
#Move the view above the center of the room
BirdView.setPosition([40,-9550,0])
#Rotate the view so that it looks down
BirdView.setEuler([0,90,0])

I added a small window using this code.
I had not any problem when I used only one computer. However, the small window on the left of the top of this attached picture appeared on each screen of the three computers while I used them.
I would like to make the window appear on only one screen.
I suppose that I can solve the problem using SETMASK code but I failed to settle the problem although I tried many times.
I would appreciate it if you can help me.

The following code shows how to use a cluster mask so the sub-window only shows up on the master:

Code:

import viz

viz.go()



maze = viz.addChild('maze.osgb')





with viz.cluster.MaskedContext(viz.MASTER):

        UpperLeftWindow = viz.addWindow(pos=(0,1.0),size=(0.2,0.4))

        UpperLeftWindow.visible(0,viz.SCREEN)

        BirdView = viz.addView()

        #Attach the bird's eye view to the upper left window

        UpperLeftWindow.setView(BirdView)

        #Move the view above the center of the room

        BirdView.setPosition([0,50,0])

        #Rotate the view so that it looks down

        BirdView.setEuler([0,90,0])

I get an error if I try to set the MaskedContext to viz.CLIENT1 can you tell me why? I think the VizWindow instance isn't valid.

The previous code sample is incorrect. Try the following instead:

Code:

import viz

viz.go()



maze = viz.addChild('maze.osgb')



UpperLeftWindow = viz.addWindow(pos=(0,1.0),size=(0.2,0.4))

UpperLeftWindow.visible(0,viz.SCREEN)

BirdView = viz.addView()

#Attach the bird's eye view to the upper left window

UpperLeftWindow.setView(BirdView)

#Move the view above the center of the room

BirdView.setPosition([0,50,0])

#Rotate the view so that it looks down

BirdView.setEuler([0,90,0])

        

# Show the window only on client 1

UpperLeftWindow.visible(0)

with viz.cluster.MaskedContext(viz.CLIENT1):

        UpperLeftWindow.visible(1)

You still need to add the window to all machines, but just make it visible on one.
