Hi all, it seems to be a bit quit in the forum.... I got a very basic question. I try to get streamlines working for me and up till now it doesn't. I got a 3D velocity field on an unstructured grid. I create glyph's for it and display it. so far so good. next I want to add streamlines so I pass the same data that I pass to autoglyph to streamlines. This results in an error message saying that streamlines expects a 3D floating point vector field. So I make an explicit vector field by extracting th positions from the field and passing it to the origin part of a construct block. next I extract the data part and compute the velocity vectors explicitly again by computing [a.0, a.1, a.2] extract the data part and pass it to the data part of the construct block. However streamlines still complains about the field not being a 3D vector field. What else do I have to do to make streamlines happy??
