It's clear that you're describing a point cloud, but you don't seem to
be aware that a point cloud doesn't define a unique surface, and that
finding a "nice" surface to go through a point cloud is a difficult
problem in general.

If your point cloud has further structure, it can be exploited.
Otherwise, you first have to give it structure; griddata and delaunay
are two functions you can use to give your point cloud a structure so
you can create a surface out of it.
