Detailed Description

Fence slice extractor for unstructured 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.

Member Function Documentation

virtual const MeXSurfaceMeshUnstructured& MiFenceSliceExtractUnstructured::extract	(	const MbVec3d &	direction,
		const std::vector< MbVec3d > &	polyline,
		const MiCellFilterI *	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& MiFenceSliceExtractUnstructured::extractScalarSet

(

const MiScalardSetI &

inputSet

)

[pure virtual]

Extracts a scalar set from the volume mesh.

The scalars are mapped onto the current extracted fence slice referring to either the line mesh or the surface mesh depending on whether extract() or extractLine() was last called.

Parameters:

inputSet

the input scalar set defined on the volume mesh

Returns:

the output scalar set defined on the latest extracted mesh

virtual const MeXVec3dSetI& MiFenceSliceExtractUnstructured::extractVec3Set

(

const MiVec3dSetI &

inputSet

)

[pure virtual]

Extracts a vector set from the volume mesh.

The vectors are mapped onto the current extracted fence slice referring to either the line mesh or the surface mesh depending on whether extractSlice() or extractLineSlice() was last called.

Parameters:

inputSet

the input vector set defined on the volume mesh

Returns:

the output vector set defined on the latest extracted mesh

virtual const MeXSurfaceMeshUnstructured& MiFenceSliceExtractUnstructured::getExtract

(

)

const [pure virtual]

Returns the result of the extraction as a mesh.

static MiFenceSliceExtractUnstructured* MiFenceSliceExtractUnstructured::getNewInstance	(	const MiVolumeMeshUnstructured &	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.
