Interpolation and volume calculation

Hi, I have a matrix representing 3D points, first I need to interpolate these points to reconstruct a surface representing a part of a sphere. My data are scattered so I am not sure I can use methods for gridded data. I want to test several methods so I tried griddata, DelaunayTri, TriScatteredInterp but I cannot figure out how to use csapi and the nurbs, do you have an idea? Then I need to calculate the volume enclosed by this open surface, do you know how I can do that? Thank you for your help
