Limits of sphere to obtain points

Hello everyone!
I have multiple points (nodes). And i plot (plot3) a sphere with coordinates of center x0,y0 and z0 with radius r. I need to obtain the points (nodes) which are inside in sphere. How i can do this? How i can obtain the limits of curvature of sphere (in x,y and z)?
Thanks!
code:
[x,y,z] = sphere();
plot3(r*x+x0, r*y+y0, r*z+z0,'k-')

What data structure do you have to describe the nodes? For example is it a struct array each element of which is a structure with elements 'x', 'y', 'z', each a scalar?

All of those nodes are on the outside of the sphere. None of them are inside the sphere.
