interesting. It might apply to attempts to use VTK as a server for <st1:City

however, the current setup works fine because the vtkWin32OpenGLRenderWindow

about vtkRenderWindow, and vtkOpenGLRenderWindow. Are such objects virtual, or

<P class=MsoNormal><SPAN class=EmailStyle19><FONT face=Arial color=black
size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">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.
