摘要： A system includes a computing device that includes a memory and a processor configured to execute instructions to perform a method that includes receiving multiple representations of one or more expressions of an object. Each representation includes position information attained from one or more images of the object. The method also includes producing an animation model from one or more groups of controls that respectively define each of the one or more expressions of the object as provided by the multiple representations. Each control of each group of controls has an adjustable value that defines the geometry of at least one shape of a portion of the respective expression of the object. Producing the animation model includes producing one or more corrective shapes if the animation model is incapable of accurately presenting the one or more expressions of the object as provided by the multiple representations.

摘要： A motion library can be created by generating motion feature vectors for at least some of multiple frames of a video sequence using a 3D mesh, each motion feature vector corresponding to characteristics of the body deformation in one of the frames. The A user can select a subset of the frames. For each frame in the subset, the user can define settings for controls of an animation character, the settings selected by the user to correspond to the body deformation in the respective frame. Mappings are generated using the settings and the motion feature vectors, the mappings regulating the controls based on multiple motion feature vectors. The motion library can be used to generate an animation from an actor performance.

摘要： A system includes a computer system capable of representing one or more animated characters. The computer system includes a blendshape manager that combines multiple blendshapes to produce the animated character. The computer system also includes an expression manager to respectively adjust one or more control parameters associated with each of the plurality of blendshapes for adjusting an expression of the animated character. The computer system also includes a corrective element manager that applies one or more corrective elements to the combined blendshapes based upon at least one of the control parameters. The one or more applied corrective elements are adjustable based upon one or more of the control parameters absent the introduction of one or more additional control parameters.

摘要： The subject matter of this specification can be embodied in, among other things, a method that includes determining a transform of a portion of constituent components of a source shape. The transform includes one or more states for the portion of constituent components of the source shape. The method also includes accessing a mapping function that associates the one or more states with one or more controls for a target shape, where the one or more controls configured for access by a user for manipulating constituent components of the target shape. The method includes outputting a transform for the target shape based on the one or more controls associated with the transformed constituent components of the source shape.

摘要： Systems and methods are described, which create a mapping from a space of a source object (e.g., source facial expressions) to a space of a target object (e.g., target facial expressions). In certain implementations, the mapping is learned based a training set composed of corresponding shapes (e.g. facial expressions) in each space. The user can create the training set by selecting expressions from, for example, captured source performance data, and by sculpting corresponding target expressions. Additional target shapes (e.g., target facial expressions) can be interpolated and extrapolated from the shapes in the training set to generate corresponding shapes for potential source shapes (e.g., facial expressions).

摘要： Consistent tessellation via topology-aware surface tracking is provided in which a series of meshes is approximated by taking one or more meshes from the series and calculating a transformation field to transform the keyframe mesh into each mesh of the series, and substituting the transformed keyframe meshes for the original meshes. The keyframe mesh may be selected advisedly based upon a scoring metric. An error measurement on the transformed keyframe exceeding tolerance or threshold may suggest another keyframe be selected for one or more frames in the series. The sequence of frames may be divided into a number of subsequences to permit parallel processing, including two or more recursive levels of keyframe substitution. The transformed keyframe meshes achieve more consistent tessellation of the object across the series.

摘要： A method is described that includes receiving, from a first device, input used to select a first object in a computer-generated environment. The first device has at least two degrees of freedom with which to control the selection of the first object. The method also includes removing, in response to the selection of the first object, at least two degrees of freedom previously available to a second device used to manipulating a second object in the computer-generated environment. The removed degrees of freedom correspond to the at least two degrees of freedom of the first device and specify an orientation of the second object relative to the selected first object. Additionally, the method includes receiving, from the second device, input including movements within the reduced degrees of freedom used to manipulate a position of the second object while maintaining the specified orientation relative to the selected first object.
