Ran in:
clc; clear all ;
I = imread('cameraman.tif') ;
[m,n] = size(I) ;
[X,Y,Z] = sphere(m-1,n-1) ;
surf(X,Y,Z,flipud(I),'FaceColor','texturemap','EdgeColor','none');
colormap(gray)

I had balck and white image... I want the white area will plot at the sphere like your code did. But the black area will not plot, and matlab leave this sphere area clear (ball grid only, or hole in the sphere somehow) Hope this is more clear
