// .NAME vtkVectorDot - generate scalars from dot product of vectors and normals (e.g., show displacement plot)
// .SECTION Description
// vtkVectorDot is a filter to generate point scalar values from a dataset.
// The scalar value at a point is created by computing the dot product
// between the normal and vector at each point. Combined with the appropriate
// color map, this can show nodal lines/mode shapes of vibration, or a
// displacement plot.
//
// Note that by default the resulting scalars are mapped into a specified
// range. This requires an extra pass in the algorithm. This mapping pass can
// be disabled (set MapScalars to off).
// .SECTION Caveats
// This class has been threaded with vtkSMPTools. Using TBB or other
// non-sequential type (set in the CMake variable
// VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.

// Description:
// Enable/disable the mapping of scalars into a specified range. This will

// scalar values will strictly be a function of the vector and normal
// data. By default, MapScalars is enabled, and the output scalar
// values will fall into the range ScalarRange.
