Detailed documentation
----------------------
The MORSE human avatar is based on a 3D model generated from MakeHuman, and
stored in human_rig.blend.
The model is rigged with an armature (`human.skeleton`), used to control the
postures of the human and to deform accordingly the human mesh.
This armature is used by MORSE as both a :doc:`sensor to read and export
the human pose <../sensors/armature_pose>` and :doc:`an actuator
<../actuators/armature>` to modify the pose.
TODO: give code examples to read and modify the pose
The armature defines 5 particular points (**IK targets**) that can be
manipulated to control the human model in a simpler way: the head, the two
wrists and the two feet.
