[R-sig-Geo] Generate isotropic noised data in 3d

[Paolo Piras]

Hi folks,
I have a 3D shape identified by n points in x,y,z, space.
I want to generate, says 1000, random shapes, each  identified by n points, whose points are random isotropic fluctuations of original points. 
I have in my mind some ways to do that but it would be helpful to have, if any, some advice from the community.
Thankyou very much in advance
best
