|
|
* @brief generate constant-time dashed streamline in arbitrary dataset
|
|
*
|
|
* vtkDashedStreamLine is a filter that generates a "dashed" streamline for
|
|
* an arbitrary dataset. The streamline consists of a series of dashes, each
|
|
* of which represents (approximately) a constant time increment. Thus, in the
|
|
* resulting visual representation, relatively long dashes represent areas of
|
|
* high velocity, and small dashes represent areas of low velocity.
|
|
*
|
|
* vtkDashedStreamLine introduces the instance variable DashFactor.
|
|
* DashFactor interacts with its superclass' instance variable StepLength to
|
|
* create the dashes. DashFactor is the percentage of the StepLength line
|
|
* segment that is visible. Thus, if the DashFactor=0.75, the dashes will be
|
|
* "three-quarters on" and "one-quarter off".
