How can I plot functions on sphere?

I have a set of N points on a unit sphere. The Cartesian coordinates of these N points are stored in X (a 3xN matrix). Further I know the value of a function f on these N points in the form of F (1xN vector).
I want to plot my function. I want a figure, like the one which we get using 'surf' function.
Any help?

You should probably use convhull to get the connections between the points (vertices):
K = convhull(points);
You can then use patch to draw an image:
patch('vertices',points,'faces',K,'cdata',F); % draw it
axis equal tight vis3d % set axis
view(3) % set camera view to a 3D position
Use help patch to get more details on how to adapt the properties of the 3d plot
