Did the time come to fix that?
Oh, BTW, if we use a function call setInertia in that new class State, then fixing that problem will be much simpler, because internally we will store this as a matrix, but the function setInertia will have two prototypes: one that accepts a 3dvector, another that accepts a matrix :)) -- Janek Kozicki | _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
