// .NAME vtkHedgeHog - create oriented lines from vector data
|
|
// .SECTION Description
|
|
// vtkHedgeHog creates oriented lines from the input data set. Line
|
|
// length is controlled by vector (or normal) magnitude times scale
|
|
// factor. If VectorMode is UseNormal, normals determine the orientation
|
|
// of the lines. Lines are colored by scalar data, if available.
