Imported point cloud - section view

Hi guys,

I have successfully imported pointclouds in PLY format and rendered them via this custom shader asset:

Point cloud importer & renderer for Unity https://github.com/keijiro/Pcx

However, I wish to create section view of the point cloud via the movement of a plane. (ie: hide points above the plane) I have two questions:

Is the fastest way to hide the points via the shader?
How would I implement something like this

Here is the link to the point cloud shader. https://github.com/keijiro/Pcx/blob/master/Assets/Pcx/Runtime/Shaders/Point.shader

I have managed to do something similar for polygons successfully via this wonderful tutorial: https://www.ronja-tutorials.com/2018/08/06/plane-clipping.html

Cheers T
