Unstructured points X,Y,Z - visualise spatial density.

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?


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.
