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

[Xiaofeng Zhao]

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.

  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
