How to plot actual 3D Contours with MATLAB !?

Hi everybody
I have a data set of points (XYZ as the coordinates) and V as the value at each point. (Each of these 4 data sets (X,Y,Z,V) are vectors e.g. 1x1000 vectors.) Also I have another vector F (e.g. 1x3000) containing faces which describes the connection of vertices. I've plotted the 3D surface using patch command. (by the use of faces & vertices)
Now here goes the problem :
How can I plot the contour lines of V (and NOT Z ) on the 3D surface !?
(Actually the contour3 function plots 3D contour lines of Z ; But I need contour lines of V. ) I want some type of function or command that gets x,y,z and plots contours of V.
Actually I want something like the pictures below :
