Does this software use the 3DMM approach or some alternative? If so is it possible for more information on the number of laser scans used to create the model?
Yes, LOOXIS Faceworx is based on a 3D morphable model derived from laser scans of real faces. It uses the 3DMM (3D Morphable Model) approach. Unfortunately, specific information on the number of laser scans used to create the model is not provided.
