Detailed Description

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".

For each dash, specify the fraction of the dash that is "on". A factor of 1.0 will result in a continuous line, a factor of 0.5 will result in dashed that are half on and half off.
