hello every one i'm working now in texture mapping so i want to get x,y,z coordinates of a 3d object of all faces of this object but i just now to get this coordinates just for one face how i can get all coordinate of all faces this is my code
nx = 120; % the size of the grid
ny = 120; % the size of the grid
x = linspace(min(v(:,1)),max(v(:,1)),nx);
y = linspace(min(v(:,2)),max(v(:,2)),ny);
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Number of x values in uniform grid
[X, Y] = meshgrid(x, y); % Create meshes for xu and yu
Z = gridtrimesh(f,v,X,Y);
where V and f are the faces and vertex
how i can get all coordinate of all faces this is my code my 3d object have 5 faces ?
