Detailed Description

concrete dataset representing a path defined by Bezier curves.

vtkPath provides a container for paths composed of line segments, 2nd-order (quadratic) and 3rd-order (cubic) Bezier curves.

Member Typedef Documentation

◆ Superclass

typedef vtkPointSet vtkPath::Superclass

Definition at line 37 of file vtkPath.h.

Member Enumeration Documentation

◆ ControlPointType

enum vtkPath::ControlPointType

Enumeration of recognized control point types:

MOVE_TO: Point defining the origin of a new segment, not connected to the previous point.
LINE_TO: Draw a line from the previous point to the current one
CONIC_CURVE: 2nd order (conic/quadratic) point. Must appear in sets of 2, e.g. (0,0) MOVE_TO (0,1) CONIC_CURVE (1,2) CONIC_CURVE defines a quadratic Bezier curve that passes through (0,0) and (1,2) using (0,1) as a control (off) point.
CUBIC_CURVE: 3rd order (cubic) control point. Must appear in sets of 3, e.g. (0,0) MOVE_TO (0,1) CUBIC_CURVE (1,2) CUBIC_CURVE (4,0) CUBIC_CURVE defines a cubic Bezier curve that passes through (0,0) and (4,0), using (0,1) and (1,2) as control (off) points.

◆ PrintSelf()

void vtkPath::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 vtkDataSet.

◆ GetDataObjectType()

int vtkPath::GetDataObjectType ( )

inlineoverridevirtual

Return what type of dataset this is.

Reimplemented from vtkDataSet.

Definition at line 43 of file vtkPath.h.

◆ InsertNextPoint() [1/3]

void vtkPath::InsertNextPoint	(	float	pts[3],
		int	code
	)

Insert the next control point in the path.

◆ InsertNextPoint() [2/3]

void vtkPath::InsertNextPoint	(	double	pts[3],
		int	code

Insert the next control point in the path.

◆ InsertNextPoint() [3/3]

Set/Get the array of control point codes:

◆ GetNumberOfCells()

vtkIdType vtkPath::GetNumberOfCells ( )

inlineoverridevirtual

vtkPath doesn't use cells.

These methods return trivial values.

Implements vtkDataSet.

Definition at line 87 of file vtkPath.h.

◆ GetCell() [1/5]

vtkCell * vtkPath::GetCell ( vtkIdType cellId )

inlineoverridevirtual

Get cell with cellId such that: 0 <= cellId < NumberOfCells.

The returned vtkCell is an object owned by this instance, hence the return value must not be deleted by the caller.

Warning: Repeat calls to this function for different face ids will change the data stored in the internal member object whose pointer is returned by this function.; THIS METHOD IS NOT THREAD SAFE. For a thread-safe version, please use void GetCell(vtkIdType cellId, vtkGenericCell* cell).

Implements vtkDataSet.

Definition at line 89 of file vtkPath.h.

◆ GetCell() [2/5]

void vtkPath::GetCell	(	vtkIdType	cellId,
		vtkGenericCell *	cell
	)

overridevirtual

Get cell with cellId such that: 0 <= cellId < NumberOfCells.

This is a thread-safe alternative to the previous GetCell() method. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Implements vtkDataSet.

◆ GetCellType()

int vtkPath::GetCellType ( vtkIdType cellId )

inlineoverridevirtual

Get type of cell with cellId such that: 0 <= cellId < NumberOfCells.

THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Implements vtkDataSet.

Definition at line 91 of file vtkPath.h.

◆ GetCellPoints()

void vtkPath::GetCellPoints	(	vtkIdType	,
		vtkIdList *	ptIds

Implements vtkDataSet.

◆ GetPointCells()

void vtkPath::GetPointCells	(	vtkIdType	ptId,
		vtkIdList *	cellIds
	)

overridevirtual

vtkPath doesn't use cells, this method just clears cellIds.

Implements vtkDataSet.

◆ GetMaxCellSize()

int vtkPath::GetMaxCellSize ( )

inlineoverridevirtual

Return the maximum cell size in this poly data.

Implements vtkDataSet.

Definition at line 106 of file vtkPath.h.

◆ Allocate()

void vtkPath::Allocate	(	vtkIdType	size = `1000`,
		int	extSize = `1000`
	)

Method allocates initial storage for points.

Use this method before the method vtkPath::InsertNextPoint().

◆ Reset()

void vtkPath::Reset ( )

Begin inserting data all over again.

Memory is not freed but otherwise objects are returned to their initial state.

◆ GetData() [1/2]

static vtkPath * vtkPath::GetData ( vtkInformation * info )

static

Retrieve an instance of this class from an information object.

◆ GetData() [2/2]

static vtkPath * vtkPath::GetData	(	vtkInformationVector *	v,

static

Retrieve an instance of this class from an information object.

◆ GetCell() [3/5]

virtual vtkCell * vtkDataSet::GetCell ( vtkIdType cellId )

virtual

Get cell with cellId such that: 0 <= cellId < NumberOfCells.

The returned vtkCell is an object owned by this instance, hence the return value must not be deleted by the caller.

Warning: Repeat calls to this function for different face ids will change the data stored in the internal member object whose pointer is returned by this function.; THIS METHOD IS NOT THREAD SAFE. For a thread-safe version, please use void GetCell(vtkIdType cellId, vtkGenericCell* cell).

virtual void vtkDataSet::GetCell	(	vtkIdType	cellId,
		vtkGenericCell *	cell
	)

virtual

Get cell with cellId such that: 0 <= cellId < NumberOfCells.

This is a thread-safe alternative to the previous GetCell() method. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED
