[Paraview] [Non-DoD Source] Re: Volume rendering with OSPRay Renderer not working with ParaView 5.3.0-RC3 (UNCLASSIFIED)

[Rick Angelini]

Joe I seem to recall that I could get PV 5.2 to crash with one of the 3 demo datasets that pop up with the splash screen when I turned on OSPRay.  You might check those datasets.    8-)

David,

I can not send my data set,
But I am experiencing similar problems
With one of visit's sample data sets.

curv3d.silo (A multi-block containing a structured curvilinear grid)

I clip it and then render it with the default volume renderer

and it works, but then when I turn on OSPRay it fails. (crashes)

Strangely enough it also fails (does not renderer visibly) in the default
renderer when I do not first clip it.


My data which is failing is instead a large unstructured grid with cell/Point
arrays

They visualize ok with the default Volume renderer but are invisible with the

OSPRay volume renderer. I have not yet found a sample I can share with you
that has the same

behavior. I will see if I can get you one though. Do you know of any similar
publicly available samples?


I have also tried the vtk analyze sample data

S01_epi_r01_001.img
S01_epi_r01_001.hdr

Which are image (uniform rectangular grids)

S01_epi_r01_001 renderers correctly with both the default volume renderer

and the OSPRay one.

Thanks,

Joe

        Hello,

        I am finding that the volume rendering is not working with

        OSPRay Renderer not working with ParaView 5.3.0-RC3.

        The volume render sample that I am testing looks fine

        when rendered with the default renderer, but when I switch to the

        OSPRay volume renderer, then nothing is shown.

        Has anyone managed to volume render data, using

        the OSPRay renderer with ParaView 5.3.0-RC3?

        Thanks,

        Joe
