I want obatin the corresponding coordinate(column and row in 2D image)of every mesh vertice. For example, in the 3D head building example, how to obtain the 2D column and rows(in one picture,which is used to building the model) of each mesh vertex after I have obtained the 3D head mesh. The 3D information (x,y,z) of every mesh vertice can be found in the *.rzi file. But how can I project these vertices to one 2D image( this mage has been used to build the 3D mesh).
     I tried to use the camera calibration in the *.rzi file,but the result is wrong.  Does the calibration parameters is not good enough, or there has other way. Please help me.
