/**

* @class vtkVectorDot
|
||
|
|
* @brief generate scalars from dot product of vectors and normals (e.g., show displacement plot)
|
||
|
|
*
|
||
|
|
* 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).
|
||
|
|
*
|
||
|
|
* @warning
|
||
|
|
* 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.
