I have a 3D dataset where each point stores the 3 components of the velocity and a scalar. I want to plot glyphs, but only at points where the scalar has a certain value (say 0). What filter can help me ignore the points with non-zero scalar value? My requirement is very similar to the “Mask Points” filter but I do not want random sampling - I want to sample points based on the scalar value.
You should extract the points of interest, and apply the glyph on the whole result.
For instance, use the
FindData panel and make a query to select points depending on the scalar, and then use
Extract Selection filter.
Thanks, you led me to the right place. I was able to use “Threshold” filter to extract the required points. I did not need to follow it up with the extract selection.
