    摘要: A first frame includes a first 2D image of a motion capture subject in the real 3D space. A 3D model is deformed into a first deformation and placing the deformed 3D model in a virtual 3D space in a first location so that the deformed 3D model corresponds to the first 2D image. A second frame includes a second 2D image of the motion capture subject in the real 3D space. 2D changes in the second 2D image relative to the first 2D image are tracked. The 2D changes are projected on the virtual 3D space as 3D constraints. Based on the second 2D image, the 3D model is again deformed into a second deformation and placing the 3D model in the virtual 3D space in a second location in conformance with the 3D constraints.

    摘要: A computer-implemented method for providing retargeting of actor motion includes: receiving, in a computer system, an input generated by user selection of at least one of multiple real-time constraint scenarios, each real-time constraint scenario corresponding to a relationship between motion capture information from an actor and a position or movement of a character driven by the motion capture information; activating, based on the selected real-time constraint scenario, one or more of multiple limb solvers for the character which determines at least a first joint angle for a corresponding character limb; registering, for at least one character limb where the corresponding limb solver is not activated, a corresponding joint angle from the motion capture information as a second joint angle; and determining a root location for the character based on at least the first and second joint angles.

    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.
