Re: [Question #681246]: something do not understand about code in polyhedra_ig2.cpp
Question #681246 on Yade changed:
Status: Open => Answered
Jan Stránský proposed the following answer:
for non-periodic simulations, it is Vector3(0,0,0)
for periodic simulations, is is shift of the second body to make the interaction meaningful
se31.position would be in python state.pos
**usually** it is the center of mass. But in general b.state.pos and b.shape.v can be quite independent.
