KeenTools FaceBuilder can help you build 3D models of faces and heads based on several photos. With FaceBuilder, you don't need to become an experienced 3D modeler to create high-quality 3D models with clean topology. You first take several photos with neutral facial expressions from different angles, and then place a model on each photo to construct a head or facial model. The generated model can be used for rigid tracking using GeoTracker or for facial gesture tracking using FaceTracker. You can also export the model from Nuke for further modification in any other 3D software.
