// .NAME vtkVectorNorm - generate scalars from Euclidean norm of vectors
|
|
// .SECTION Description
|
|
// 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.
