WorldViz User Forum - How to vary the transparency of the scene

Hello,

.alpha changes the transparency of an OBJECT. But I would like to vary the transparency of part of the SCENE. I tried creating a subview and subwindow, but that only makes part of the scene black.

The following is my code. Is there any way I can show, in the black area, the original scene but make it blurred?

Code:

import viz

viz.go()



viz.add('gallery.ive')



subView1 = viz.addView()

subWindow1 = viz.addWindow(pos=(0,1.0), size=(0.2,1.0))

corner of main window

subWindow1.setView(subView1)

subView1.setScene(2)



subView2 = viz.addView()

subWindow2 = viz.addWindow(pos=(0,1.0), size=(1.0,0.2))

subWindow2.setView(subView2)

subView2.setScene(3)



subView3 = viz.addView()

subWindow3 = viz.addWindow(pos=(0.8,1.0), size=(0.2,1.0))

subWindow3.setView(subView3)

subView3.setScene(4)



subView4 = viz.addView()

subWindow4 = viz.addWindow(pos=(0,0.2), size=(1.0,0.2))

subWindow4.setView(subView4)

subView4.setScene(5)

Thanks a lot,
