vtkDashedStreamLine Class Reference
#include <vtkDashedStreamLine.h>
Detailed Description
generate constant-time dashed streamline in arbitrary datasetvtkDashedStreamLine 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".

Member Function Documentation
| static vtkDashedStreamLine* vtkDashedStreamLine::New | ( | ) | [static] |
Construct object with step size set to 1.0.
Reimplemented from vtkStreamLine.
| virtual const char* vtkDashedStreamLine::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkStreamLine.
| static int vtkDashedStreamLine::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkStreamLine.
| virtual int vtkDashedStreamLine::IsA | ( | const char * | name | ) | [virtual] |
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkStreamLine.

| void vtkDashedStreamLine::PrintSelf | ( | ostream & | os, | |
| vtkIndent | indent | |||
| ) | [virtual] |
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkStreamLine.
| virtual void vtkDashedStreamLine::SetDashFactor | ( | double | ) | [virtual] |
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.

This is called by the superclass. This is the method you should override.
