A simple hack to allow 4 contacts is shown in TetrahedronsTest example.

But he has already done spheropolyhedrons, and it works. I haven't meet anybody who would want to implement the same thing in an unfamiliar way, when he already has this thing working. I think that adding spheropolyhedrons will be an interesting thing too. It's a bit different than facets, will allow doing some comparisons, etc. -- Janek Kozicki | _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
