Remove points from a mesh with a cutting plane

Hello,

I have a 3D cubic mesh in which I want to remove some points. For that I will choose a point (X,0,0) in the x axis and make a plane with a given angle. Thus, I want to check which points of the mesh are above the plane in order to remove them.

Thank you.
