How can I change the color of tiles in a spherical graph?

Use the [X,Y,Z] = sphere syntax to return the x,y,z coordinates and then use h=surf(X,Y,Z) to produce the same sphere and return the surface handle. You can also control color by updating properties of the surface object h.

In S1 you can see the properties.

You can use the Cdata propery to change the color of each tile for example.

[X,Y,Z] = sphere;

figure

s1 = surf(X,Y,Z)

s1 =

Surface with properties: EdgeColor: [0 0 0] LineStyle: '-' FaceColor: 'flat' FaceLighting: 'flat' FaceAlpha: 1 XData: [21×21 double] YData: [21×21 double] ZData: [21×21 double] CData: [21×21 double] Show all properties

colorbar;

axis equal

figure;

s2 = surf(X,Y,Z)

s2 =

Surface with properties: EdgeColor: [0 0 0] LineStyle: '-' FaceColor: 'flat' FaceLighting: 'flat' FaceAlpha: 1 XData: [21×21 double] YData: [21×21 double] ZData: [21×21 double] CData: [21×21 double] Show all properties

s2.CData = zeros(21,21,3);

s2.CData(12,3,:) = [1 0 0] % R G B

s2 =

Surface with properties: EdgeColor: [0 0 0] LineStyle: '-' FaceColor: 'flat' FaceLighting: 'flat' FaceAlpha: 1 XData: [21×21 double] YData: [21×21 double] ZData: [21×21 double] CData: [21×21×3 double] Show all properties
