    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.

    摘要： A system includes a computing device that includes a memory configured to store instructions. The system also includes a processor configured to execute the instructions to perform a method that includes receiving multiple representations of one or more expressions of an object. Each of the representations 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 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： In one general aspect, a method is described. The method includes generating a positional relationship between one or more support structures having at least one motion capture mark and at least one virtual structure corresponding to geometry of an object to be tracked and positioning the support structures on the object to be tracked. The support structures has sufficient rigidity that, if there are multiple marks, the marks on each support structure maintain substantially fixed distances from each other in response to movement by the object. The method also includes determining an effective quantity of ray traces between one or more camera views and one or more marks on the support structures, and estimating an orientation of the virtual structure by aligning the determined effective quantity of ray traces with a known configuration of marks on the support structures.
