all,</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=995254401-08032010>I have an issue with
code that is using vtkPointPicker to pick points displayed using
vtkGlyph3D.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=995254401-08032010></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=995254401-08032010>Now I have the
picking working great for most of the glyphs - using
vtkGlyph3D->GeneratePointIdsOn(); and I am able to select glyphs and display
a sphere at the selected glyph location.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN

<DIV><FONT face=Arial size=2><SPAN class=995254401-08032010>My problem is that
while this works perfectly 99% of the time - there are certain glyphs that are
either very difficult to pick (sometimes impossible it seems) or I have to click
about 20 pixels or so above or next to the glyph for the pick to work. Has
anyone seen this issue and/or can suggest a fix?</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN

<DIV><FONT face=Arial size=2><SPAN class=995254401-08032010>Why would picking
work perfectly for most glyphs but not for some others - when all of the glyphs
are generated from the same simple pointset using the same
vtkGlyph3D filter?</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=995254401-08032010>Any help would be
muchly appreciated - thanks</SPAN></FONT></DIV>
