How to fit a 2d image onto 3d mesh?

I have a face image (read using imread) that has labelled face features (matrix stored in [x y] format)
I have generated depth information (a 3d mesh) for each of the labelled points, and have a matrix in `[x y z]` format, where the coordinates x and y are the same as that of the points. It looks like this:
How do I fit or warp the original image (at least the region enclosed by the points) over the 3d mesh, using the x and y coordinates for mapping? I know I have to do a lot of interpolation in the 3d mesh before I see good results, but I'd like to know how to fit an image to that
I've looked at similar threads http://www.mathworks.in/matlabcentral/newsreader/view_thread/256787 and http://www.mathworks.com/matlabcentral/answers/91858-is-it-possible-to-perform-texture-mapping-within-matlab, but the instructions there warp the face out of position with the 3d mesh (i.e. the face part of the image is not aligned with the 3d mesh)

hi. how is this going, I also meet this kind of problem, i need to fit 2d image on 3d mesh with specific coordinate correspondences. Hope to discuss with you.
