Missing methods/mismatched method signatures in gInteractiveOpticX example source code

After downloading latest GVDB sources, compilation of gInteracttiveOptix sample generates errors:

error C2039: ‘UpdateVolume’: is not a member of ‘OptixScene’
error C2039: ‘ResizeOutput’: is not a member of ‘OptixScene’
error C2039: ‘Render’: is not a member of ‘OptixScene’

error C2660: ‘OptixScene::SetMaterialParams’: function does not take 2 arguments
error C2660: ‘OptixScene::SetMaterialParams’: function does not take 2 arguments
error C2660: ‘OptixScene::AddVolume’: function does not take 6 arguments

It seems, some corrections are necessary either in optix_scene.h or in main_interactive_oprix.cpp.

Is there any chance that it could be done?

Thank you very much in advance.

Actually, it turns out that all optix_ files from sample_utils folder have duplicates in gInteractiveOptix folder.

So, to compile the sample it is necessary to use optix_scene files from sample_utils.
Unfortunately, it is not clear how to merge them correctly, which would be more reasonable solution.

Hopefully, this duplication will be eliminated in the next release.
