Question: Plotting Surface representing the graph of Spherical Function

Hi,

I have a vector of points which sample the graph of a spherical function, say f. My definition for the graph of a spherical function is :

points[k] = f(x_k) * x_k     where  x_k \in S^2   .

Right now I use pointplot3d to obtain a rough visualization of my function. However, I'd like a plot that looks like a solid surface, the way plot3d output can look. 

Any ideas?

Thanks for any help!
