Hi,  
I have successfully installed and tested Nvidia Index volume rendering plugin with a sample wavelet source. I now want to use it for visualizing outputs of my fluid simulations (finite volume code with cell centered data values) in xdmf and vtk file formats. But in representation option I don’t see Nvidia Index available for my loaded data. Any help will be very useful.

A wavelet was rendered successfully

You’ll have to load the plugin before you open your dataset. Try doing that as the first step.

@utkarsh.ayachit I have already tried that with no luck both with vtk and xdmf outputs.

In that case, I suspect your data is not volumetric but instead a surface or maybe multiblock of volumetric datasets. If the latter, try using the `Resample To Image` filter to resample to an 3D uniform grid and then you should be able to volume render it.

@utkarsh.ayachit  
Thanks a lot! Using the filter I was able to do the volume rendering.
