How would one load a .csv file containing unstructured point data, formatted as X,Y,Z,[scalars…] and visualise spatial point density in slice or volume representation?

Cheers

A very simple explanation would be as follows:

- After reading the csv file, the **TableToPoints** filter can be used to create 3D points from the loaded data.

- Then, to display the slice plane for the point cloud, the **PointPlaneInterpolator** filter is available.

- For volume rendering of the point cloud, the **PointVolumeInterpolator** filter can be used.

For each Interpolator, you may need to adjust the Kernel type and the  
corresponding parameters in order to display the slice or volume view well.
