Hi there,
Recently I have been looking into Yade's tetra element. There is a question concerning me:

In yade, I first added a tetraPoly:
    O.bodies.append(utils.tetraPoly([[0,0,0],[1,0,0],[0,1,0],[0,0,1]]))
And I looked its details:
O.bodies[0].shape.v
It returned:
[Vector3(-0.7071067811865476,-0.408248290463863,-0.14433756729740643),
 Vector3(2.7755575615628914e-17,0,0.43301270189221935),
 Vector3(-2.220446049250313e-16,0.8164965809277261,-0.14433756729740646),
 Vector3(0.7071067811865477,-0.40824829046386313,-0.14433756729740652)]
At first I thought it might be a local coordinates, however the center of this tetra was:
Vector3(0.25,0.25,0.25)
So I want to know how is tetra.shape.v calculated and how to change it into the normal global coordinates?
