Hi all, I’m trying to visualize large datasets (~1 billion points) on my local desktop and have been using ParaView up to 30M points (~100M cells) for 3D data. I’m thinking I can then use Datashader to view very large 2D slices (500M points) as Datashader has very nice data aggregation tools.

I mostly just want to know if anyone has done something like this before. Maybe ParaView/VTK already has the ability to view large 2D surfaces with data aggregation, but I get the sense ParaView mostly relies on distributed processing for scaling.

Thanks!

Hi @Connor_McClellan

What do you mean by “large 2D surfaces with data aggregation” ?

> I get the sense ParaView mostly relies on distributed processing for scaling.

ParaView does support distributed processing and multithreaded processing, but I dont see the link.

Best,
