extractLine() [1/2]

virtual const MeXLineMeshUnstructured & MiClipLineExtractUnstructured::extractLine ( const MbVec3< double > &  normal, double  distance, const MiCellFilterI *  cellFilter = NULL  )

pure virtual

Computes a 3D polyline as the result of the intersection of the surface mesh and the given plane.

Parameters

normal	Vector normal to the plane
distance	Position of the plane relatively to the origin along the normal
cellFilter	The cell filter object.

Returns

An unstructured line mesh representing the clip line

extractLine() [2/2]

virtual const MeXLineMeshUnstructured & MiClipLineExtractUnstructured::extractLine ( const MbVec3d &  direction, const std::vector< MbVec3d > &  polyline, const MiCellFilterI *  cellFilter = NULL  )

pure virtual

Computes a 3D polyline as the result of the intersection of several planes and the surface mesh.

The arbitrary planes (or fences) are defined by a polyline and a direction. The clip line extracted is returned as an unstructured line 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 line mesh representing the clip line

extractScalarSet()

virtual const MeXScalardSetI & MiClipLineExtractUnstructured::extractScalarSet ( const MiScalardSetI &  inputSet )

pure virtual

Extracts a scalar set from the surface mesh.

The scalars are mapped onto the current extracted clip sline.

Parameters

inputSet

the input scalar set defined on the surface mesh

Returns

the output scalar set defined on the resulting line mesh

extractVec3Set()

virtual const MeXVec3dSetI & MiClipLineExtractUnstructured::extractVec3Set ( const MiVec3dSetI &  inputSet )

pure virtual

Extracts a vector set from the surface mesh.

The vectors are mapped onto the current extracted clip line.

Parameters

inputSet

the input vec3 set defined on the surface mesh

Returns

the output scalar set defined on the resulting line mesh

getExtract()

virtual const MeXLineMeshUnstructured & MiClipLineExtractUnstructured::getExtract ( ) const

pure virtual

Returns the result of the extraction as a mesh.

getNewInstance()

static MiClipLineExtractUnstructured * MiClipLineExtractUnstructured::getNewInstance ( const MiSurfaceMeshUnstructured &  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.
