[Paraview] Accelerated volume rendering in 3.8.0-RC1?

[Moreland, Kenneth]

There is no direct way to do that.  The problem is that image data is constrained to have uniform spacing and be axis aligned whereas structured grids are not.  You could build a filter to do the conversion, but it would have to rely on resampling or warping of the grid.

Thanks, Ken.
That's good to know. I always thought Tetra and HAVS are only CPU based.
And is there a way to convert my structured grid data to image data in order to enable other accelerated rendering?

Best,

The new GPU accelerated volume rendering algorithm is only for Image Data.

Your data must be unstructured, because you are seeing the
unstructured grid volume rendering algorithms, which have not been
updated.
