1. A computer implemented method of motion capture, the method comprising:
- accessing a 3D model of a subject;
associating the 3D model of the subject with a 2D representation of the subject in a plurality of frames;
identifying a change to the 2D representation of the subject between two or more of the plurality of frames; and
deforming the 3D model in a virtual 3D space, wherein the deforming is based on;
the identified change to the 2D representation; and
at least one constraint restricting how the 3D model can be deformed.

Abstract
A method of motion capture may include accessing a 3D model of a subject, and associating the 3D model of the subject with a 2D representation of the subject in a plurality of frames. The method may also include identifying a change to the 2D representation of the subject between two or more of the plurality of frames, and deforming the 3D model in a virtual 3D space. In some embodiments, the deforming may be based on the identified change to the 2D representation and at least one constraint restricting how the 3D model can be deformed.
