Detailed Description

Helper class to build a DataSet by iteratively adding points and cells.

This class allows you to specify a DataSet by adding points and cells one at a time.

AddCell() [1/3]

void vtkm::cont::DataSetBuilderExplicitIterative::AddCell	(	const vtkm::UInt8 &	shape,
		const std::vector< vtkm::Id > &	conn
	)

Add a cell to the DataSet.

Parameters

[in]	shape	Identifies the shape of the cell. Use one of the vtkm::CELL_SHAPE_* values.
[in]	conn	List of indices to the incident points.

AddCell() [2/3]

void vtkm::cont::DataSetBuilderExplicitIterative::AddCell	(	const vtkm::UInt8 &	shape,
		const vtkm::Id *	conn,
		const vtkm::IdComponent &	n
	)

Add a cell to the DataSet.

Parameters

[in]	shape	Identifies the shape of the cell. Use one of the vtkm::CELL_SHAPE_* values.
[in]	conn	List of indices to the incident points.
[in]	n	The number of incident points (and the length of the conn array).

AddCell() [3/3]

void vtkm::cont::DataSetBuilderExplicitIterative::AddCell

(

vtkm::UInt8

shape

)

Start adding a cell to the DataSet.

The incident points are later added one at a time using AddCellPoint. The cell is completed the next time AddCell or Create is called.

Parameters

[in]

shape

Identifies the shape of the cell. Use one of the

AddCellPoint()

void vtkm::cont::DataSetBuilderExplicitIterative::AddCellPoint

(

vtkm::Id

pointIndex

)

Add an incident point to the current cell.

Parameters

[in]

pointIndex

Index to the incident point.

AddPoint() [1/4]

template<typename T >

vtkm::Id vtkm::cont::DataSetBuilderExplicitIterative::AddPoint ( const T &  x, const T &  y, const T &  z = 0  )

inline

Add a point to the DataSet.

Parameters

[in]	x	The x coordinate of the newly created point.
[in]	y	The y coordinate of the newly created point.
[in]	z	The z coordinate of the newly created point.

Returns

The index of the newly created point.

AddPoint() [2/4]

vtkm::Id vtkm::cont::DataSetBuilderExplicitIterative::AddPoint	(	const vtkm::FloatDefault &	x,
		const vtkm::FloatDefault &	y,
		const vtkm::FloatDefault &	z = 0
	)

Add a point to the DataSet.

Parameters

[in]	x	The x coordinate of the newly created point.
[in]	y	The y coordinate of the newly created point.
[in]	z	The z coordinate of the newly created point.

Returns

The index of the newly created point.

AddPoint() [3/4]

vtkm::Id vtkm::cont::DataSetBuilderExplicitIterative::AddPoint

(

const vtkm::Vec3f &

pt

)

Add a point to the DataSet.

Parameters

[in]

pt

The coordinates of the point to add.

Returns

The index of the newly created point.

AddPoint() [4/4]

template<typename T >

vtkm::Id vtkm::cont::DataSetBuilderExplicitIterative::AddPoint ( const vtkm::Vec< T, 3 > &  pt )

inline

Add a point to the DataSet.

Parameters

[in]

pt

The coordinates of the point to add.

Returns

The index of the newly created point.

Begin()

void vtkm::cont::DataSetBuilderExplicitIterative::Begin

(

const std::string &

coordName = "coords"

)

Begin defining points and cells of a DataSet.

The state of this object is initialized to be ready to use AddPoint and AddCell methods.

Parameters

[in]

coordName

(optional) The name to register the coordinates as.

Create()

vtkm::cont::DataSet vtkm::cont::DataSetBuilderExplicitIterative::Create

(

)

Produce the DataSet.

The points and cells previously added are finalized and the resulting DataSet is returned.
