[vtk-developers] vtkCompositeManager offscreen

[Charles Law]

Hello Randy,

The composite manager class is supposed to do what you want.  We have 
ParaView export Tcl scripts that use the composite manager.  It asks the 
user whether they want off-screen rendering.

It manually sets the render window's OffScreenRenderingOn() flag.

It also uses the flag "ManualOn()".  With this flag on, all processes have 
to call Render (not just process 0).  It is used without the render window 
interactor.  The main purpose of this flag is to allow the script to change 
parameters when saving out multiple images for an animation.

Charles.
