This is truly a monumental and massive piece of work. I’ve never seen the human body so well represented, even with facial expressions ! I’ve used a few other “posing” packages but this project wins my prize, and this one is “free” ! Every bone and joint is represented using Inverse Kinematics and a rigging/bone system. This means that the model responds to movements imposed on it in real time in a realistic way. It also another great example of the power of Blender. Its a unified way of working with software so we don’t need to have endless separate applications all with different ways of doing things.
My figure above is a work in progress.
