摘要： A method of transferring a facial expression from a subject to a computer-generated character and a system and non-transitory computer-readable medium for the same. The method can include receiving an input image depicting a face of a subject; matching a first facial model to the input image; generating a displacement map representing of finer-scale details not present in the first facial model using a regression function that estimates the shape of the finer-scale details. The displacement map can be combined with the first facial model to create a second facial model that includes the finer-scale details, and the second facial model can be rendered, if desired, to create a computer-generated image of the face of the subject that includes the finer-scale details.

摘要： There is provided a method for use by a system including a hardware processor and a memory storing a three-dimensional (3D) character data having a topology mesh describing a character. The method includes stabilizing the 3D character data by removing a translational motion and a rotational motion from the 3D character data, determining a range of motion of a plurality of points of the topology mesh describing the character, identifying a plurality of poses for generating an animation, where each of the plurality of poses includes a unique configuration of the plurality of points of the topology mesh, and creating an animatronic including a plurality of actuators configured to instantiate the plurality of poses for generating the animation.

摘要： Techniques and systems are described for generating an anatomically-constrained local model and for performing performance capture using the model. The local model includes a local shape subspace and an anatomical subspace. In one example, the local shape subspace constrains local deformation of various patches that represent the geometry of a subject's face. In the same example, the anatomical subspace includes an anatomical bone structure, and can be used to constrain movement and deformation of the patches globally on the subject's face. The anatomically-constrained local face model and performance capture technique can be used to track three-dimensional faces or other parts of a subject from motion data in a high-quality manner. Local model parameters that best describe the observed motion of the subject's physical deformations (e.g., facial expressions) under the given constraints are estimated through optimization. The optimization can solve for rigid local patch motion, local patch deformation, and the rigid motion of the anatomical bones. The solution can be formulated as an energy minimization problem for each frame that is obtained for performance capture.

摘要： Methods, systems, and computer-readable memory are provided for determining time-varying anatomical and physiological tissue characteristics of an animation rig. For example, shape and material properties are defined for a plurality of sample configurations of the animation rig. The shape and material properties are associated with the plurality of sample configurations. An animation of the animation rig is obtained, and one or more configurations of the animation rig are determined for one or more frames of the animation. The determined one or more configurations include shape and material properties, and are determined using one or more sample configurations of the animation rig. A simulation of the animation rig is performed using the determined one or more configurations. Performing the simulation includes computing physical effects for addition to the animation of the animation rig.
