[vtkusers] VTK and GUI - vtkRenderWindow - Virtual or Physical?

[Frank Gao]

Hi Experts,

I have a question about vtkRenderWindow, and vtkOpenGLRenderWindow. Are such
objects virtual, or have to be physical by setting the parent window ID?

The requirement behind this question is here. Suppose an application must
separate its window display and interaction from its internal code. The
application needs to set a virtual vtkOpenGLRenderWindow with interactors
that are also virtual, and binding them with a physical window whenever
necessary. Simply put, make vtkOpenGLRenderWindow and the interactor purely
‘server’ objects to return bitmaps (or video streams?). These server objects
are fully functional and independent of physical implementation. By doing
this, the application never needs to get into vtk code to change files such
as vtkMFCWindow.

A real scenario for this. If this is possible, with a .Net wrapper, one can
easily use Win Forms as render window.

It would be tremendously helpful if the answer is YES, or can be YES. Your
replies are highly appreciated.

Thanks,

Frank Gao
