I have a data set that has a 308D vector associated with the PointData:
descriptors->SetNumberOfComponents(308);
descriptors->SetName("Descriptors");
descriptors->SetNumberOfTuples(polyData->GetNumberOfPoints());
...
polyData->GetPointData()->AddArray(descriptors);
I want to apply a Calculator filter to filter the points by their
descriptor magnitude. In the Calculator filter, I choose
Attribute mode: PointData
Then if I click the "Vectors" drop down box, I see two other vectors
(colors and coords), but not "Descriptors". If I click on the
"Scalars" drop down box, I see 308 entries for a single dimension of
the descriptor vector with their index appended after an underscore
(ie. Descriptors_0 ...Descriptors_307), but not the whole vector. Is
there a way to apply a norm(Descriptors) operation in the Calculator
filter with this data set?
Thanks,
David
