[Paraview] parallel processing in volume rendering and Merge Blocks filter ...

[Andy Bauer]

Hi Ufuk,

ParaView doesn't currently support volume rendering of multiblock datasets,
even in serial, so using the Merge Blocks filter is probably the best way
to do any volume rendering of your dataset.

Cheers,
Andy
