From what I can tell it is unable to interpolate to a specific pre-defined set of points and only interpolates to an equally spaced grid of a certain number of points in x, y, z, which is not what I want.

A compromise would be to be able to interpolate to a number of points within a particular range range, e.q. theta - -40 to +40 for example, but I don't think it can do this either as I am assuming the number points are scaled between 0 and 1.

If anyone can instruct on how to use grid3 to achieve what I am after I would be very grateful.

Thanks.
