Drawing a surface boundary around scattered points

I was wondering if there was a way to collect all of the boundary points to a 3D scatter plot? All of the points are generated randomly. I guess more specifically if I have a structure that has a field with 100 data points how could I collect the boundary points from this field?

Boundary can mean many things. Are you looking for the points on the convex hull of this group of points?

Thank you for your reply! Yes, I do mean the convex boundary.

This could help:

You could also use most triangulation methods for this; for example Triangulate.jl
(but check whether licensing constraints are fine for your purpose)
