// .NAME vtkVectorDot - generate scalars from dot product of vectors and normals (e.g., show displacement plot)
|
|
// .SECTION Description
|
|
// vtkVectorDot is a filter to generate scalar values from a dataset.
|
|
// The scalar value at a point is created by computing the dot product
|
|
// between the normal and vector at that point. Combined with the appropriate
|
|
// color map, this can show nodal lines/mode shapes of vibration, or a
|
|
// displacement plot.
