[Paraview] [Non-DoD Source] Re: Volume rendering with OSPRay Renderer not working with ParaView 5.3.0-RC3 (UNCLASSIFIED)

[David E DeMarle]

Just remembering now that OSPRay (currently) only has volume rendering
implemented for image data.

Please try the resample to image filter and that should look OK in OSPRay.

Also - please file an issue on gitlab to remind me to make the UI warn
whenever ParaView hands OSPRay something incompatible rather than just
rendering nothing.
