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);
