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.
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. -Ken On 6/2/09 6:16 AM, "John Biddiscombe" <[email protected]> wrote: don't use polyvertex. a single polyvertex consisting of N points is a single cell. Algorithms like threshold dump it. Use polydata or unstructured grid with one vertex per cell. Either that or fix the threshold filter to work properly. JB Hello, I try to visualise parts of a point cloud (POLYVERTEX) using the threshold-filter. But any threshold-value will remove _all_ points instead of only a few. I wonder if this is a bug... I attached a example-xmf-file. If you you try to visualise only the points with 'type'>0 all points disappear, even though there are points with type=1.0 Any idea?
