Is it possible to implement a way to send a rendering scene (made in Python) to VR kind of like ParaView’s “Send to OpenVR” button?
If so, I’m definitely going to try to implement this for [`vtki`](http://docs.vtki.org/)

Yes, just replace your code as follows
vtkRendererWindow --\> vtkOpenVRRenderWindow
vtkRenderer --\> vtkOpenVRRenderer
vtkRenderWindowInteractor --\> vtkOpenVRRenderWindowINteractor
vtkCamera --\> vtkOpenVRCamera
You need all four of those classes to be created and set for it to work. You cannot rely on the default camera/interactor creation. But make those 4 changes and you should be good.

So all of those classes are located under `VTK/Rendering/OpenVR/` on the master branch of VTK. Would I need to build VTK with a specific option to enable those? And is this supported on all operating systems?

You have to turn on the RenderingOpenVR module and they are supported on windows. I have heard of them being built on Linux but never tried it personally.

Hello sir,
vtkOpenVRRenderWindow ,
vtkOpenVRRenderer
,vtkOpenVRRenderWindowINteractor,
vtkOpenVRCamera
these functions are not available in python it would be a great helpful if you update VTK for these functions.

I think this is fixed in vtk master. I can create them in python at least.

What might be the CMake option to turn on the OpenVR module if I wanted to slightly modify [this recipe](https://github.com/conda-forge/vtk-feedstock/blob/f3f4058c0c2ef3b9f92a877978c52dfe6696c7f6/recipe/build.sh#L31)?

So can’t we make OpenVR using vtk wrapping Python code?
Finally, I want to make Paraviewweb + VR system

I think you can. Seems to work for me. I just tried
```auto
>>> cam2 = vtk.vtkOpenVRCamera()
>>> win = vtk.vtkOpenVRRenderWindow()
>>> ren = vtk.vtkOpenVRRenderer()
```
and it seemed to do the right thing

Which version of vtk did you use?
The vtk version I am using is vtk 8.1.2 which I pip installed through the following command:
pip install vtk
