rolling sphere lightning detection simulation

create an application to simulate the rolling sphere method for lightning protection. see link for description of the method; https://axis-india.com/rolling-sphere-method/

this links illustrates the desired outcome: https://www.youtube.com/watch?v=fBkl6fcujCY&ab_channel=DHKLightningProtection
the object that will be used in the simulation is a 3d model that can be imported as a file to the program.

the spheres radius should be adjustable

the surface where the sphere is touching the object needs to be highlighted

any programming language is approved aslong as the outcome is as the youtube video illustrates
