<DIV><FONT face=Arial size=2>Hello, I'm new VTK user and have some problems with
visualizing vectors.</FONT></DIV>
<DIV><FONT face=Arial size=2> I' ve computed vector field and save it into
structured grid. (as vectors)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Then I use "vtkGlyph2D" to visualize it, with the
source</FONT></DIV>
<DIV><FONT face=Arial size=2>object arrow (from vtkGlyphSource2D). This goes
well, but then I tried vtkHedgeHog class and the result</FONT></DIV>
<DIV><FONT face=Arial size=2>doesn't corespondent with the previous
"arrows". </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Also when I wanted to generate streamlines
expecting "curves along the arrows" I got some "mysterious" lines</FONT></DIV>
<DIV><FONT face=Arial size=2>and I don't want to believe these are streamlines
of the field. Those arrows should be in tangetial direction,
shouldn't? Will someone explain what I'm doing bad? </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks a
lot
Martin</FONT></DIV>

and data are in atachmentes</FONT></DIV>
