Hi, Actually, I want to do texture mapping in Matlab. I do this by surface function. With this function, we can map a 2D image to 3D surface. After that, I want to save this mapping as a colored .ply file. How to do this in Matlab? Code below show an example of texture mapping that provided by Matlab help. Suppose that I want to save this surface as a colored .ply file.

[XD,YD,ZD] = peaks(25);

load clown

C = flipud(X);

figure surface(XD, YD, ZD, C,... 'FaceColor','texturemap',... 'EdgeColor','none',... 'CDataMapping','direct');

colormap(map)

view(-35,45);
