Hello,

I am new to using ParaView and just have a couple of questions about it. I wanted to know if the software supports any method of reducing the number of samples of an uploaded point cloud. I also was wondering if it supports any method of volume meshing.

Thank you

Hi and welcome.

Decimate filter should do the trick

> I also was wondering if it supports any method of volume meshing.

Delaunay3D should do the trick. Keep in mind that it have some limitations.

Because you are starting with a point cloud, you might also try using `Mask Points`. It gives lots of extra options that are not available to more generic filters like `Decimate`. Turn on the advanced options to see the lots of different ways to, for example, randomly sample the points.
