Cxx: Add OpenVR volume rendering example

Since I had some issues with volume rendering in OpenVR on VTK 9.2 (https://discourse.vtk.org/t/openvr-problems-with-vtk-9-2/10992), I've added this simple example as demo for future testing.

changed the description

Please generate a test image and put it in src/Testing/Baseline/Cxx/GeometricObjects/ I usually just use ctest, the name of the image will be TestOpenVRVolume.png. This will be automatically used for the web page.

Apologies the path for the test image should be src/Testing/Baseline/Cxx/VolumeRendering/

Compare with previous version

I usually just use ctest

Can ctest somehow automatically create screenshots, and from an OpenVR render window? I couldn't figure out how to do this, so I manually created a screenshot from SteamVR's "Display VR View" window; however, I cannot add it to the given location, since this is in LFS storage and my account doesn't seem to have permissions to write there.

Can you upload the png image here?

Testing uploading/downloading image:

@codeling It seems to work, I can upload/download an image.

Here it is:

I don't have the fancy black borders for the separate eye views as you though ;)

Got it, thanks. I'll merge, then add in the image. The image looks really impressive. I didn´t do the fancy black borders, the original contributor did them.

merged

I also did a reformat of the C++ file, we don't use tabs (two spaces instead), and follow the VTK style.

All done OpenVRVolume
