摘要： A computer-implemented method includes identifying a representation of a feature of an animated character by inverting an skinned representation of the feature in one position. The inversion includes a non-linear inversion of the skinned representation of the feature. The method also includes skinning the identified feature representation to produce the animated character in another position.

摘要： Among other disclosed subject matter, a computer-implemented method for generating a surface representation of an item includes identifying, for a point on an item in an animation process, at least first and second transformation points corresponding to respective first and second transformations of the point. Each of the first and second transformations represents an influence on a location of the point of respective first and second joints associated with the item. The method includes determining an axis for a cylindrical coordinate system using the first and second transformations. The method includes performing an interpolation of the first and second transformation points in the cylindrical coordinate system to obtain an interpolated point. The method includes recording the interpolated point in a surface representation of the item in the animation process.

摘要： A system includes a computing device that includes a memory for storing one or more animations (e.g., a first and a second animation), and a model compressor. The model compressor quantifies similarities between the first animation and the second animation, and, groups the first and second animation based upon the quantified similarities. The model compressor is also configured to compress the first animation and the second animation to produce a first model that represents the content of the first animation and the second animation.

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 computing device that includes a memory for storing instructions. The computing device also includes a processor configured to execute the instructions to perform a method that includes combining, in a nonlinear manner, a first set of vertex displacements that represent the difference between a first animated expression and a neutral animated expression with a second set of vertex displacements that represent the difference between a second animated expression and the neutral animated expression. The number of vertices associated with the first set of vertex displacements of the first animated expression is equivalent to the number of vertices associated with the second set of vertex displacements of the second animated expression.
