Hai,

One of the method is:
[x,y,z] = sphere(30);
surf(x+a, y+b, z+c) % where (a,b,c) is center of the sphere

and second method is:
r=1;
phi=linspace(0,pi,30);
theta=linspace(0,2*pi,40);
[phi,theta]=meshgrid(phi,theta);

x=r*sin(phi).*cos(theta);
y=r*sin(phi).*sin(theta);
z=r*cos(phi);

Hope it helps,
Ashwini

hai,

Instead of surf .. try mesh
