I’ve been using the integrate variables filter in ParaView which maps to `vtkIntegrateAttribute`. My dataset has both point and cell data and the filter helpfully gives integrals for both though only the cell data has volume or area field.

Could I ask what happens for point data? Is the integral computed with some sort of quadrature or trapezoidal rule?
