Generate twisted body poses #122

Hi, Thanks for sharing this code. I am running the smplify-x code and find that sometimes the model generates twisted body poses like image listed below. 03_img Do you have any clue why this happens ? I don't use the interpenetration function, but I think it's related to that ? Since the interpenetration does not happen.

@penincillin This is probably an artifact of the initialization. The heuristic assumes that the person is standing. When that is not true, the translation along z has a large value and the optimization tries to compensate with weird betas.

@vchoutas I see, that makes sense. Thanks for your reply !
