NVIDIA index error/ Paraview 5.10.1 and 5.10.0 on Mac book Pro M1

Hi,

I’m trying to use NVIDIA index using pvNVIDIAindex on M1 Mac book pro where input file is xdmf, h5 format.
When I try change the representation to NVIDIA IndeX` for 3D velocity data, I get the following error.

nvindex: PVPLN  init error: The data array 'velocity_save_deg_2' has 3 components, which is not supported by NVIDIA IndeX.
nvindex: PVPLN  init error: Failed to initialize the mapper in vtknvindex_irregular_volume_mapper::Render.
nvindex: PVPLN  init error: NVIDIA IndeX rendering was aborted.

I saw an exmple of speeding up volume rendering with NVIDIA index, so I thought it could be used for 3D velocity, but, as the error message says, it seems like it can not be used for 3D data.

Am I doing something wrong here or NVIDIA index can not be used for 3D data?
I’m happy to share my data if necessary.

Best,

Hi @Kei_Yamamoto

I have no issues visualizing a image data with a 3 componenent points arrays with the nvidia index plugin here.

Sharing your data may be needed indeed.

Hi @mwestphal

Sorry for not responding a while ago. I tried NVIDIA index again but got the same problem.

Please use the data here and let me know if it works for you.

Nevermind, NVIDIA index indeed does not support three components array.

You can extract single component using the calculator to visualize them.

You can also use the Extract Component filter to extract single components.
