I think you have to call the function "glLoadIdentity();" before you draw your world, so that the axis are resetted....

Oh, an other possibility is to use te glPushMatrix() and glPopMatrix() commands, before, and after you draw you models, so that your translations for the world are restored after your modelcode...
