to attempts to use VTK as a server for <st1:City w:st="on"><st1:place w:st="on">AJAX</st1:place></st1:City>.
For Windows Forms, however, the current setup works fine because the
vtkWin32OpenGLRenderWindow will happily receive events from and draw into the
Frame of a Windows Form because Windows Forms expose their HWND handle.<o:p></o:p></span></font></p>

<p class=MsoNormal><span class=EmailStyle17><font size=2 color=black
face=Arial><span style='font-size:10.0pt'>I have a question about
vtkRenderWindow, and vtkOpenGLRenderWindow. Are such objects virtual, or have
to be physical by setting the parent window ID? <o:p></o:p></span></font></span></p>

<p class=MsoNormal><span class=EmailStyle17><font size=2 color=black
face=Arial><span style='font-size:10.0pt'>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. <o:p></o:p></span></font></span></p>

<p class=MsoNormal><span class=EmailStyle17><font size=2 color=black
face=Arial><span style='font-size:10.0pt'>A real 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>

<p class=MsoNormal><span class=EmailStyle17><font size=2 color=black

the answer is YES, or can be YES. Your replies are highly appreciated.<o:p></o:p></span></font></span></p>
