Thanks for the quick response, Seb!
Regarding the data location, it will be saved on the server where Paraview Web or paraview Glance is located. Both the server and the client that opening paraview web/glance will be GPU based workstations, so they can do the rendering when needed.
The main purpose is to use VR or AR equipment to visualize results so user can get better better ideas regarding the results.
Based on the above, which option do you think is better for my purpose, Paraview Web or Paraview Glance?
