Summary:A 3D surface morphing method based on conformal parameterization for creation of 3D animation of facial expressions is revealed. Prepare a 3-dimensional first human face and a 3-dimensional second human face. Prepare a first unit disk and a second unit disk in a two-dimensional surface form, corresponding to the first human face and the second human face respectively. Then use a first mapping unit to map the first human face and the second human face to the first unit disk and the second unit disk respectively. Use a matching module to construct a surface matching function between the two unit disks. Use a second mapping module to map the surface matching function for getting a 3D matching function. Use an interpolation module to compute the 3D matching function multiple times and get a plurality of smooth deformable surfaces between the first human face and the second human face.
