Point Interpolation


I have a csv file with ID, X, Y, Z and value data.
I first open the csv file and apply. Then, I use the Table to Points filter to visualize it in ParaView.
My point distribution resembles something similar to a sphere. However, when I try to interpolate (using the Point Volume Interpolator filter), my sphere turns into a cube.
Is there a way to interpolate while keeping the shape of the point data distribution?

Try using the Delauney 3D filter on your points. This will draw tetrahedra between the points to fill out the volume. As long as your data are convex and not too big, this should do what you want.
