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.

Tests:
vtkPath (Tests)

Member Typedef Documentation

Definition at line 40 of file vtkPath.h.

Member Enumeration Documentation

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.

vtkCell* vtkPath::GetCell ( vtkIdType  cellId)
inlineoverridevirtual

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

THIS METHOD IS NOT THREAD SAFE.

Implements vtkDataSet.

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.

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

void vtkPath::GetCellPoints ( vtkIdType  ,
vtkIdList ptIds 
)

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

Implements vtkDataSet.

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

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

Implements vtkDataSet.

int vtkPath::GetMaxCellSize ( )
inlineoverridevirtual

Return the maximum cell size in this poly data.

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

Method allocates initial storage for points.

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

void vtkPath::Reset ( )

Begin inserting data all over again.

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