[vtkusers] Re: Display a 2D image beside a 3D object

[Goodwin Lawlor]

Hi Jean-Michel,

You can use two vtkRenderers in separate half of the render window- one to
handle the vtkImageActor and one to handle the 3D object.

For example:


vtkImageActor actor2D
vtkActor actor3D

vtkRenderer ren2D
    #just the left half of render window
    ren2D SetViewport 0 0 0.5 1
    ren2D AddActor2D actor2D
vtkRenderer ren3D
    #just the right half of render window
    ren3D SetViewport 0.5 0 1 1
    ren3D AddActor actor3D

vtkRenderWindow renWin
    renWin AddRenderer ren2D
    renWin AddRenderer ren3D
