Very slow rendering of 3D EBSD data

ParaView Support

Hi,

I am currently trying to visualise a pretty large 3D dataset from a serial sectioning experiment using paraview (please note I am using version 5.4.1. as could not find a way to untick “map scalars” in new version). I am using a new MacBook Pro 2020 with 16GB memory and Intel Iris plus graphics 1536 MB. The dataset contains 271,000,000 cells!! It is a dream3D HDF5 file and contains a number of different data arrays, I have managed to compress the total file size down to ~5GB by getting rid of unrequired data arrays but cannot shrink it further. When manipulating the data (e.g. clipping, slicing) it is incredibly slow and can take up to 15 minutes to render the volume, the process bar gets stuck on “Geometry representation with faces” for ages.

My question is, is there anything I can do to speed up the volume rendering such as resampling the data? Or do I simply need to use a more powerful computer?

Many thanks,

Al

Hi,
I am using Paraview 5.8 for the visualization of FIB-SEM volumes. I opened the volume in .tiff format (150 MB) and I translated it to align it with another volume and changed its representation from outline to volume and it is very slow. Then, it says “the software is not responding” and then I ended up with closing the software and reopening it and I did this several times and I have always the same issue.
I do not how to fix the problem.
I am working with a pretty powerful computer (256 Go of memory, GPU NVIDIA Quadro RTX 4000).

Many thanks,
