<div>Hello,</div>
<div>I tried to use vtkGlyphSouce2D and vtkActor2D.</div>
<div>It is almost ok, but the problem is that the arrow(refenerce vector) can't be scaled when zooming in and out.</div>
<div>Laster, I tried to use vtkGlyphSource2D and vtkActor.</div>
<div>The arrow can be scaled properly, but it can be rotated too. </div>
<div>What i need is a arrow which can be scaled, but cann't rotated.</div>
<div>e.g.</div>
<div> --> scaled ------>, or -></div>
<div> --> rotated -->, </div>
<div> </div>
<div>Thanks.</div>

<div>>Hello Everyone,<br>>I am visualizing a velocity field.<br>>And I wanna put a reference vector at the right-up corner.<br>>The reference vector has fixed direction, like --->. That is to say it can't be rotated.
<br>>But it need Scale properly when zooming in/out.<br>>How can i realize it?<br>>Does it feasible in VTK?<br>>Thanks a lot.<br>><br>>huangl<br> </div>
