Member Function Documentation

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]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkCell.

int vtkPolyLine::IsTypeOf (  const char *    type )  [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 vtkCell.

virtual int vtkPolyLine::IsA (  const char *    type )  [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 vtkCell.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkCell.

int vtkPolyLine::GenerateSlidingNormals (  vtkPoints *   ,
vtkCellArray *   ,
vtkDataArray *   
) 
 

Given points and lines, compute normals to lines. These are not true normals, they are "orientation" normals used by classes like vtkTubeFilter 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).

vtkCell* vtkPolyLine::MakeObject (    )  [virtual]
 

See the vtkCell API for descriptions of these methods.

Reimplemented from vtkCell.

int vtkPolyLine::GetCellType (    )  [inline, virtual]
