hello every one

I would like to map a texture onto a 3-D object (.stl) i have compute the face and the vertice of the 3d object

fv = stlread ( 'house.stl' );

I=imread('brique.gif')

v = fv.vertices;

f=fv.faces;

x = linspace(min(v(:,1)),max(v(:,1)),nx);

y = linspace(min(v(:,2)),max(v(:,2)),ny);

% [x,y] = meshgrid(x,y);

Z = gridtrimesh(f,v,x,y);

figure;

surf(x,y,Z,'facecolor','texturemap',...

'cdata',I,'edgecolor','none');

when i run my programs i get bad result so how i can project my texture (I] on the mesh all surface of my 3d object
