<DIV><FONT face=Arial size=2>Hi Simon</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Here's a vtkArrowSource (based
on vtkConeSource ) that I knocked together a while back. I was going to
put a bit more work into it (eg. normals) and testing before submitting it but
you're welcome to try it out. You can adjust resolution, radius, length and
the relative size of tail dimensions (radius and length) wrt to head
dimensions. It might work for you in low resolution. Any feedback
welcome.</FONT></DIV>

<DIV><FONT size=2>Hi All,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I want to display vector orientation and magnitude using
arrows.</FONT></DIV>
<DIV><FONT size=2>Is there a way to do this. I looked at the vtkHedgeHog
class but this seems to draw lines</FONT></DIV>
<DIV><FONT size=2>only (no arrow tip). The vtkGlmph2D has an arrow but is of
course only for 2D where as my</FONT></DIV>
<DIV><FONT size=2>data is 3D. The vtkGlmph3D can be used with a cone (for
example) but I tried this a it looks</FONT></DIV>
<DIV><FONT size=2>messy to me (unless you use a high resolution for the
cone, but this gets slow!)</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Any ideas??</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Thanks</FONT></DIV>
