You can pass pointer to your own function (careful... it must be static function, since member functions have different prototype (they receive "this" pointer as hidden first argument)). What's the problem? Do you need the C function to get more data than just x,y,z?
In that function (even if it is static), you can use Omega()::instance().getScene() to get shared_ptr<Scene>. (Most libs that take function pointers to custom functions let you pass (void*) pointer to that function, though) v _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
