The balance defines the manikin by a projection of the Center of Gravity (COG) on the support
polygon of the manikin. The manikin is in balance if the point's
projection is inside the polygon.
You can display the support polygon of manikin's balance in the viewer. The color of the
support polygon changes from green to red if the manikin loses their
balance.
You see the transparent support polygon of the manikin when verifying the COG in display. If
the manikin is out of balance, the polygon becomes red instead of green.
The shape of the support polygon changes according to the change of
posture of the manikin's lower body. The following pictures represent
the case where the manikin' is in balance (COG project inside support
polygon) and when they are not (COG projection outside support polygon).
The support polygon defines as the convex polygon of the outside portion of two feet.
