Hi,
I have a Mesh (Vertices and Faces). I want to project an RGB (or greyscale) Image on the mesh surface. Something like the first example in the this page https://www.mathworks.com/help/images/ref/warp.html.
However, the previouse example based on XYZ surface not a Mesh. Is there an alternative for a Mesh?
Thanks!

You can use the same arguments used to create the mesh to create the warped surface, then plot the mesh and hold the plot while you plot the projected images plot.
[X,Y] = meshgrid(-8:.5:8);
R = sqrt(X.^2 + Y.^2) + eps;
Z = sin(R)./R;
mesh(X,Y,Z);
hold
[I,map] = imread('forest.tif');
warp(X,Y,Z,I,map);
