Member Function Documentation

static vtkPolyLine* vtkPolyLine::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual const char* vtkPolyLine::GetClassName ( ) [virtual]

Reimplemented from vtkCell.

static int vtkPolyLine::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkCell.

virtual int vtkPolyLine::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkCell.

static vtkPolyLine* vtkPolyLine::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkCell.

void vtkPolyLine::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 vtkCell.

static int vtkPolyLine::GenerateSlidingNormals	(	vtkPoints *	,
		vtkCellArray *	,
		vtkDataArray *
	)			`[static]`

Given points and lines, compute normals to lines. These are not true normals, they are "orientation" normals used by classes like vtkTubeFilte that control the rotation around the line. The normals try to stay pointing in the same direction as much as possible (i.e., minimal rotation).

		vtkCellArray *	,
		vtkDataArray *	,
		double *	firstNormal
	)			`[static]`

Given points and lines, compute normals to lines. These are not true normals, they are "orientation" normals used by classes like vtkTubeFilte that control the rotation around the line. The normals try to stay pointing in the same direction as much as possible (i.e., minimal rotation).
