Detailed Description

Fence slice extractor for structured volume meshes

A fence slice is an unstructured surface mesh defined by the intersection of several arbitrary planes (the fences) with a volume mesh. These fences are defined by a polyline and a direction. Each segment of the polyline is extruded along the direction to form a clipped plane slice. Thus, each fence goes through a segment of the polyline. Each plane slice is clipped by the extrusion of the 2 endpoints of each segment in the direction. The extracted fence slice is an unstructured surface.

virtual const MeXSurfaceMeshUnstructured& MiFenceSliceExtractIjk::extract	(	const MbVec3d &	direction,
		const std::vector< MbVec3d > &	polyline,
		const MiCellFilterIjk *	cellFilter = NULL
	)			[pure virtual]

Builds the topology and geometry of a fence slice intersecting the volume mesh.

Returns:

the fence slice extracted as an unstructured surface mesh.

Parameters:

	direction	vector defining the direction of the fences
	polyline	set of points defining the position of the fences
	cellFilter	The cell filter object.

Returns:

An unstructured surface mesh representing the fence slice

virtual const MeXScalardSetI& MiFenceSliceExtractIjk::extractScalarSet

(

const MiScalardSetIjk &

inputSet

)

[pure virtual]

Extracts a scalar set from the volume mesh.

The scalars are mapped onto the current extracted fence slice.

Parameters:

inputSet

the input scalar set defined on the volume mesh

Returns:

the output scalar set defined on the latest extracted mesh

Implemented in MiFenceSliceExtractUnstructuredIjk.

virtual const MeXVec3dSetI& MiFenceSliceExtractIjk::extractVec3Set

(

const MiVec3dSetIjk &

inputSet

)

[pure virtual]

Extracts a vector set from the volume mesh.

The vectors are mapped onto the current extracted fence slice.

Parameters:

inputSet

the input vector set defined on the volume mesh

Returns:

the output vector set defined on the latest extracted mesh

Implemented in MiFenceSliceExtractUnstructuredIjk.

virtual const MeXSurfaceMeshUnstructured& MiFenceSliceExtractIjk::getExtract

(

)

const [pure virtual]

Returns the result of the extraction as a mesh.

static MiFenceSliceExtractIjk* MiFenceSliceExtractIjk::getNewInstance	(	const MiVolumeMeshRegular &	mesh,
		bool	parallel = true,
		MiTessellator *	tessellator = NULL
	)			[static]

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

Parameters:

	mesh	The input mesh
	parallel	When true, tries to create an extract module using a parallel algorithm to speed up the extraction.
	tessellator	The tessellator object used for tessellating non linear cells (quadratic,...).

Note:

Only some of the extraction algorithms have a parallel implementation.
