[vtkusers] Opacity in Points representation

[Sergiy Tkachuk]

David,

When I load file *demoopacity.pvsm *attached, I have the following
output in ParaView 3.12.0:


ERROR: In ..\..\..\..\source\ParaViewCore\ServerImplementation\vtkSIProxyDefinitionManager.cxx,
line 543

vtkSIProxyDefinitionManager (07DF77F0): No proxy that matches:
group=misc and proxy=ViewLayout were found.

ERROR: In ..\..\..\..\source\ParaViewCore\ServerManager\vtkSMDeserializer.cxx,
line 62

vtkSMStateLoader (08D492C8): Could not create a proxy of group: misc
type: ViewLayout

5000

12.75 0.0 0.0

25.5 0.0 0.0

38.25 0.0 0.0

... // a lot of points follow here

255.0 255.0 255.0


Is it expected output?


Thanks,

Sergiy
