<DIV>Hi, </DIV>
<DIV> I draw a spline, but I don't know whether it is closed or not. </DIV>
<DIV> are there any good methods that could detect a spline whether closed or not in VTK? or are there any good suggestion? thank you very much!</DIV>
<DIV> I am using VTK and MFC to detect the spline's state.</DIV>
