Detailed Description

Probe at a given location in a structured volume mesh

This class can be used to evaluate the value of a data set in the given mesh at any location. The probe is internally building an octree onto the curvilinear meshes. This octree can be optimized by setting three environment variables (see MiPointProbeUnstructured and SoPreferences).

Member Function Documentation

virtual void MiPointProbeIjk::getCellId	(	size_t &	i,
		size_t &	j,
		size_t &	k
	)			const [pure virtual]

Gets the ids of the cell of the mesh containing the current location of the probe.

i, j and k are set to UNDEFINED_ID if the current location of the probe is outside the mesh.

Parameters:

[out]	i	the first id of the cell.
[out]	j	the second id of the cell.
[out]	k	the last id of the cell.

static MiPointProbeIjk* MiPointProbeIjk::getNewInstance	(	const MiVolumeMeshCurvilinear &	mesh,
		bool	parallel = true
	)			[static]

Factory method returning a new instance of a class implementing this abstract class.

Parameters:

	mesh	The input mesh
	parallel	When true, tries to create an extract module using a parallel algorithm to speed up the extraction.

Note:

Only some of the extraction algorithms have a parallel implementation.

static MiPointProbeIjk* MiPointProbeIjk::getNewInstance	(	const MiVolumeMeshRectilinear &	mesh,
		bool	parallel = true
	)			[static]

Factory method returning a new instance of a class implementing this abstract class.

Parameters:

	mesh	The input mesh
	parallel	When true, tries to create an extract module using a parallel algorithm to speed up the extraction.

Note:

Only some of the extraction algorithms have a parallel implementation.

static MiPointProbeIjk* MiPointProbeIjk::getNewInstance	(	const MiVolumeMeshRegular &	mesh,
		bool	parallel = true
	)			[static]

Factory method returning a new instance of a class implementing this abstract class.

Parameters:

	mesh	The input mesh
	parallel	When true, tries to create an extract module using a parallel algorithm to speed up the extraction.

Note:

Only some of the extraction algorithms have a parallel implementation.

template<typename _T >

_T MiPointProbeIjk::getValue

(

const MiDataSetIjk< _T > &

dataset

)

const [inline]

Gets the value at the current probe location in the given dataset. The returned value is meaningless if the probe location is outside the mesh (when isFound() is false).

Reimplemented in MiPointProbeUnstructuredIjk.

virtual void MiPointProbeIjk::getWeight

(

std::vector< double > &

weight

)

const [protected, pure virtual]

Gets the weights at the current probe location.

This weights are used by getValue() to compute a value at the current probe location.

virtual bool MiPointProbeIjk::isFound

(

)

const [pure virtual]

Returns:

true if the current location of the probe is inside the mesh, false otherwise.

virtual bool MiPointProbeIjk::moveLocation	(	const MbVec3d &	point,
		size_t	cellIdI,
		size_t	cellIdJ,
		size_t	cellIdK,
		const MiCellFilterIjk *	cellFilter = NULL
	)			[pure virtual]

Moves the current probe location at the given point.

This method is similar and gives the same result as setLocation(). But, first it looks for the containing cell in the neighborhood of the cell having id (cellIdI,cellIdJ,cellIdK) . Then, if the neighborhood of this given cell does not contain the given point this method searches in the whole mesh like the method setLocation().

For instance, moveLocation() could be used instead of setLocation() when the cell containing the point is already known, or when the displacement of the probe is not too large compared to the cell's size at the previous location of the probe. In this case, use getCellId() to retrieve the cells indices.

Parameters:

[in]	point	The destination point of the probe.
[in]	cellIdI	input cell I index used as initial search criteria. If UNDEFINED_ID, this method is equivalent to setLocation().
[in]	cellIdJ	input cell J index used as initial search criteria. If UNDEFINED_ID, this method is equivalent to setLocation().
[in]	cellIdK	input cell K index used as initial search criteria. If UNDEFINED_ID, this method is equivalent to setLocation().
[in]	cellFilter	The cell filter.

Returns:

true if this location is inside the mesh, false otherwise.

virtual bool MiPointProbeIjk::setLocation	(	const MbVec3d &	point,
		const MiCellFilterIjk *	cellFilter = NULL
	)			[pure virtual]

Sets the current probe location at the given point and looks for the cell containing this point. If the probe location is inside a cell not accepted by the optional filter, this methods returns false.

Parameters:

[in]	point	The destination point of the probe.
[in]	cellFilter	The cell filter.

Returns:

true if this location is inside the mesh, false otherwise.
