Geometry based muscle modeling for facial animation
Types of facial models 2. In a further implementation, the facial MOCAP data are acquired separately in a sitting position and the facial animation generated is blended in keyframed body shots. After 3-D reconstruction, the markers are represented by spatial positions i. Our PDE-based parameterisation scheme can produce and animate a high-resolution 3D face with a relatively small number of parameters. Output consists of face images in a GL screen window.
A muscle model for animation three-dimensional facial expression
This program is a fairly primitive direct descendent of the original Utah face model. In the tuning process, artistic input is taken from the artist or user by modifying weights so that the overall expression suite closely matches the desires of a user. However, because the weights are obtained using mathematical methods e. Textures for facial models. As a final step, the muscle geometry file will have to be adapted to the face geometry you provide.
In another implementation, a control device such as a cyber glove is used to input control commands, and finger movements are retargeted onto the digital facial model. A method of animating a digital facial model, the method including: Automatic determination of facial muscle activations from sparse motion capture marker data. Control Simple keyboard bindings are used to control the face to avoid code overload. You will undoubtedly find many ways to improve and enhance the model, its user interface, and its associated data files. The modified action units are incorporated into the FACS matrix as updates.
It will be appreciated that other configurations of cameras, capture volumes, and markers can be used. In another example, different types of motion capture techniques and markers can be used, such as optical markers other than infrared, active optical e. The above description of the disclosed implementations is provided to enable any person skilled in the art to make or use the invention. Creating a Facial Model. In one implementation, the media device is an optical disc drive.
