Oh, yes, there would be a problem if there is penetration of the sphere into the surface... Hm... OTOH if htere is information about mutual angle between adjacent facets on the edge, that could be used. The contact detection would actually try to see if there is contact with adjacent facet's plane, and if not, make the contact with the edge. It is getting complicated.
Thanks for the paper, I will have a look at that.
