The last few years have seen great maturation in the computation speed and control methods needed to portray 3D virtual humans suitable for real interactive applications. Various dimensions of real-time virtual humans are considered, such as appearance and movement, autonomous action, and skills such as gesture, attention, and locomotion. A virtual human architecture includes low level motor skills, mid-level PaT-Net parallel finite-state machine controller, and a high level conceptual action representation that can be used to drive virtual humans through complex tasks. This structure offers a deep connection between natural language instructions and animation control.
