<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>In the short term you can get around this problem by first running your data through the glyph filter using the 2D Glyph/Vertex as the glyph type. Another work around is to use the clip filter with a clip type of Scalar instead of the Threshold filter. In the long term, John is right. You should write out your xmf file with a single vertex cell per point.<BR>
<BR>
As far as “fixing” the threshold filter, the current operation is correct, but I’ve thought for a long time that the clip-by-scalars functionality mentioned above should be available from within the threshold filter. Rather than have an All Scalars checkbox, there should be a tri-state Any Scalar/All Scalars/Clip option.<BR>

Either that or fix the threshold filter to work properly.<BR>

Hello,<BR>
<BR>
I try to visualise parts of a point cloud (POLYVERTEX) using the<BR>
threshold-filter.<BR>
<BR>
But any threshold-value will remove _all_ points instead of only a few.<BR>
I wonder if this is a bug...<BR>
<BR>
I attached a example-xmf-file. If you you try to visualise only the<BR>
points with 'type'>0 all points disappear, even though there are points<BR>
with type=1.0<BR>
<BR>
Any idea?<BR>
<BR>
Greetings<BR>
