honeybee_vtk.filter module

Filters to be used with VTK.

honeybee_vtk.filter.filter_using_thresholds(polydata: vtkmodules.vtkCommonDataModel.vtkPolyData, lower_threshold: float = None, upper_threshold: float = None) → vtkmodules.vtkCommonDataModel.vtkPolyData[source]

Apply a threshold filter to a polydata.

This function will remove the cell or points of the Polydata that fall outside of the given thresholds. This function first applies the vtkThreshold filter to the polydata and then uses the vtkDataSetSurfaceFilter to turn the vtkUnstructuredGrid into a vtkPolyData.

Parameters

  • polydata – A vtkPolyData object.

  • lower_threshold – The lower threshold value. This threshold value is included in the thresholding operation. For example, if you want the threshold to be greater than 0 then set the value 0.1. If None, lower threshold will be infinite.

  • upper_threshold – The upper threshold value. This threshold value is included in the thresholding operation. For example, if you wan to the threshold to be lower than 1 then set the value 0.99. If None, upper threshold will be infinite.

Returns

A vtkPolyData object.
