<p class="MsoNormal">I believe the factory mechanism will replace any instantiations of vtkRenderWindow with vtkOpenVRRenderWindow if it is linked into the executable. From what I have seen that is the trick. The executable has to be linked against the vtkOpenVR
module for the autoinit to work. <o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Now for Slicer I have no idea how they create their RenderWindow. If they are explicitly creating a subclass of vtkRenderWindow then the factory code will not work because it is targeted at the generic vtkRenderWindow level. A slicer person
could maybe tell you more (or digging through the code). I think slicer may also open multiple renderwindows, for the OpenVR stuff I think you would really only want to have one window. etc. <o:p></o:p></p>
