trying to do. Separating UI and internal code is my basic intent, and also I am
not trying to use the .Net wrapper for the whole VTK. However, I am still
struggling to get it work. The error I received is that some object is busy,
which made me think that there are conflicts somewhere.<o:p></o:p></span></font></p>

helpful for you.<br>
<br>
I splittet my application into two parts. GUI runs as a managed Win Form<br>
and the numerical parts are done in a separate DLL which is native-x86.<br>
And - to come closer to your question - yes - i have not found problems<br>
at this time by letting VTK render into a Forms-Picturebox.<br>
<br>
I know that VS 2003/2005 can handle managed / unmanaged Code in the same<br>
executable but i didnt tried this way ( splitting has some advantages<br>
for me ).<br>
<br>
Hope this helps,<br>
Tom<br>

to attempts to use VTK as a server for <st1:place w:st="on"><st1:City w:st="on">AJAX</st1:City></st1:place>.
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=EmailStyle19><font size=2 color=black

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=EmailStyle19><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>

possible, with a .Net wrapper, one can easily use Win Forms as render window.<o:p></o:p></span></font></span></p>
