Problem with voronoi pattern on Pipe


I’m new to grasshopper but using it for my bachelor thesis.

Can anyone tell me how I can put a voronoi pattern on a pipe (also built with grasshopper)?

I tried to Brep the surface of the pipe to have a rectangular form that I can use to form the Voronoi pattern on. And then kind of project that on the pipe.

Is that possible? Or should I do it differently?

Thanks for help!

Goal is to have a pattern like this on the pipe
