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

extract()

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

extractScalarSet()

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

extractVec3Set()

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

getExtract()

virtual const MeXSurfaceMeshUnstructured & MiFenceSliceExtractUnstructured::getExtract ( ) const

pure virtual

Returns the result of the extraction as a mesh.

getNewInstance()

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.
