<body class='hmmessage'><div dir='ltr'>Thanks again, that does the trick. I thought GetOutput() was also supposed to call Update() automatically. <br><br>Out of curiosity, was this something that was introduced in VTK6? The last time I worked with VTK it with 5.10, and I remember using SetInput() without the intermediate Update()-s.
