Jan Stránský posted a new comment: Hello, > just multiplying a scaling factor is not feasible. The vertice coordinates can not be changed directly the vertices can be changes, but they must be set at once (similar to setting one component of b.state.pos) ### b = Body() print b.state.pos b.state.pos[0] = 1 # does not work print b.state.pos b.state.pos = (1,0,0) # works print b.state.pos ### for your case: ### v1 =(0,0,0) v2 = (1,0,0) v3 =(1,1,0) f1 = facet((v1,v2,v3),wire=False) O.bodies.append(f1) print f1.shape.vertices print [f1.state.pos + f1.state.ori*v for v in f1.shape.vertices] # move facet 1 f1 = O.bodies[0] mv = (1,0,0) f1.state.pos += mv print f1.shape.vertices print [f1.state.pos + f1.state.ori*v for v in f1.shape.vertices] # scale vertices vs = f1.shape.vertices # original vertices vs = [v*0.5 for v in vs] # scaled vertices f1.shape.vertices = vs # vertices set at once print f1.shape.vertices print [f1.state.pos + f1.state.ori*v for v in f1.shape.vertices] ### cheers Jan -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
