Now, in fact, the task of capturing the movement of one subject is solved. There is, of course, its own specifics. For example, a scanned subject and a 3D model should have skeletal models of the same design and should not radically differ in proportion. They gave an example. An ordinary person was scanned, and the upper half of the body was hypertrophied in the model. In some racks, such a model will look unnatural. For example, a person leaning forward or leaning back with normal proportions maintains balance, but the model should visually fall. While this is corrected manually. Although a solution has already been proposed to programmatically change the rack in order to move the center of gravity.
