NAME
vtkDashedStreamLine - generate constant-time dashed streamline in arbitrary dataset
SYNOPSIS
#include "/opt/vtk-c++/graphics/vtkDashedStreamLine.h"
class VTK_EXPORT vtkDashedStreamLine : public vtkStreamLine
vtkDashedStreamLine();
static vtkDashedStreamLine *New() {return new vtkDashedStreamLine;};
const char *GetClassName() {return "vtkDashedStreamLine";};
void PrintSelf(ostream& os, vtkIndent indent);
void SetDashFactor(float);
float GetDashFactor();
DESCRIPTION
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 "threequarters on" and "one-quarter off".

SUMMARY
void SetDashFactor(float)
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.
