◆ IsA()

virtual vtkTypeBool vtkPolyLine::IsA ( const char *  name)

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.

◆ PrintSelf()

void vtkPolyLine::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

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.

◆ GenerateSlidingNormals() [1/2]

static int vtkPolyLine::GenerateSlidingNormals ( vtkPoints pts,
vtkCellArray lines,
vtkDataArray normals 
)
static

Given points and lines, compute normals to the 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) w.r.t the firstNormal (which is computed if firstnormal=nullptr). Always returns 1 (success). Note that it is possible to thread this computation by setting "threading=true". However make sure that none of the points are used more than one time if threading is enabled, otherwise a data race will be produced.

◆ GenerateSlidingNormals() [2/2]

static int vtkPolyLine::GenerateSlidingNormals ( vtkPoints pts,
vtkCellArray lines,
vtkDataArray normals,
double *  firstNormal,
bool  threading = false 
)
static

Given points and lines, compute normals to the 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) w.r.t the firstNormal (which is computed if firstnormal=nullptr). Always returns 1 (success). Note that it is possible to thread this computation by setting "threading=true".
