Hello everybody,

I would like to know if I can use an image as a texturemap for a patch object. I know that it works with a surface but I can't find an equivalent for a patch object.

Exemple of an image with texturemap on a surface :

load topo topo topomap1    % load data 
[x,y,z] = sphere(50);          % create a sphere 
s = surface(x,y,z);            % plot spherical surface
s.FaceColor = 'texturemap';    % use texture mapping
s.CData = topo;                % set color data to topographic data
s.EdgeColor = 'none';          % remove edges
s.FaceLighting = 'gouraud';    % preferred lighting for curved surfaces
s.SpecularStrength = 0.4;      % change the strength of the reflected light
light('Position',[-1 0 1])     % add a light
axis square off                % set axis to square and remove axis
view([-30,30])                 % set the viewing angle
