# Usage

vtkVectorNorm is a filter that generates scalar values by computing Euclidean norm of vector triplets. Scalars can be normalized 0<=s<=1 if desired.

Note that this filter operates on point or cell attribute data, or both. By default, the filter operates on both point and cell data if vector point and cell data, respectively, are available from the input. Alternatively, you can choose to generate scalar norm values for just cell or point data.

To create an instance of class vtkVectorNorm, simply invoke its constructor as follows

      obj = vtkVectorNorm

# Methods

The class vtkVectorNorm has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, `obj` is an instance of the vtkVectorNorm class.

- `string = obj.GetClassName ()`
- `int = obj.IsA (string name)`
- `vtkVectorNorm = obj.NewInstance ()`
- `vtkVectorNorm = obj.SafeDownCast (vtkObject o)`
- `obj.SetNormalize (int )` - Specify whether to normalize scalar values.
- `int = obj.GetNormalize ()` - Specify whether to normalize scalar values.
- `obj.NormalizeOn ()` - Specify whether to normalize scalar values.
- `obj.NormalizeOff ()` - Specify whether to normalize scalar values.
- `obj.SetAttributeMode (int )` - Control how the filter works to generate scalar data from the input vector data. By default, (AttributeModeToDefault) the filter will generate the scalar norm for point and cell data (if vector data present in the input). Alternatively, you can explicitly set the filter to generate point data (AttributeModeToUsePointData) or cell data (AttributeModeToUseCellData).
- `int = obj.GetAttributeMode ()` - Control how the filter works to generate scalar data from the input vector data. By default, (AttributeModeToDefault) the filter will generate the scalar norm for point and cell data (if vector data present in the input). Alternatively, you can explicitly set the filter to generate point data (AttributeModeToUsePointData) or cell data (AttributeModeToUseCellData).
- `obj.SetAttributeModeToDefault ()` - Control how the filter works to generate scalar data from the input vector data. By default, (AttributeModeToDefault) the filter will generate the scalar norm for point and cell data (if vector data present in the input). Alternatively, you can explicitly set the filter to generate point data (AttributeModeToUsePointData) or cell data (AttributeModeToUseCellData).
- `obj.SetAttributeModeToUsePointData ()` - Control how the filter works to generate scalar data from the input vector data. By default, (AttributeModeToDefault) the filter will generate the scalar norm for point and cell data (if vector data present in the input). Alternatively, you can explicitly set the filter to generate point data (AttributeModeToUsePointData) or cell data (AttributeModeToUseCellData).
- `obj.SetAttributeModeToUseCellData ()` - Control how the filter works to generate scalar data from the input vector data. By default, (AttributeModeToDefault) the filter will generate the scalar norm for point and cell data (if vector data present in the input). Alternatively, you can explicitly set the filter to generate point data (AttributeModeToUsePointData) or cell data (AttributeModeToUseCellData).
- `string = obj.GetAttributeModeAsString ()` - Control how the filter works to generate scalar data from the input vector data. By default, (AttributeModeToDefault) the filter will generate the scalar norm for point and cell data (if vector data present in the input). Alternatively, you can explicitly set the filter to generate point data (AttributeModeToUsePointData) or cell data (AttributeModeToUseCellData).
