Hello,

I have a set of N 3D points together with N values of a function f on those points.
I would like to perform an integration of f over the volume defined by the set of points (the volume is therefore quite complicated).

I don't have that much idea on how to proceed. I was thinking on approximating my volume by a set of cubes, and then perform interpolation of my data on some gauss points of the cubes.
Does anyone have ideas on this problem?
Thanks,
Cyrille
