a PolyData's points and then interacting with a specific glyph.<br>
<br>

<br>
I trick the interactor into thinking a new object (MoveActor) is what<br>
it should be interacting with. I "spawns" a ghost glyph. When the<br>
interaction is complete (OnMiddleButtonUp) I try to update the<br>
underlying point in the data set. This update does work (the actual<br>
data point is changed), but the positions of the glyphs are not<br>
updated! Shouldn't the pipeline take care of this (since the polydata<br>
is connected to the glyphFilter which is connected to the mapper which<br>
is connected to the renderer)?<br>
<br>
Any comments on what I've done here?<br>
<br>
Thanks,<br>
<br>
