<DIV><FONT face=Arial size=2>I believe the short answer is NO. The role of
the render windows are not just creating the 2D image. They're also
responsible for rendering the image to the display according to the
hardware/platform.</FONT></DIV>

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

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial; mso-bidi-font-size: 12.0pt">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.

scenario for this. If this is possible, with a .Net wrapper, one can easily
use Win Forms as render window.<o:p></o:p></SPAN></FONT></SPAN></P>
