Detailed Description

Tessellated surface mesh extractor for unstructured and non linear 2D mesh.

Builds a tessellated linear surface mesh from non linear 2D mesh. The tessellation is done by using the given MiTessellator (see tessellate()).

extractPoints()

virtual const MeXPointMeshCurvilinear & MiTessellatedSurfaceExtract::extractPoints ( const MiCellFilterI *  cellFilter = NULL )

pure virtual

Builds a new point mesh by collecting all cell nodes of the input mesh given to the factory method getNewInstance().

Parameters

[in]

cellFilter

The optional cell filter. surface cells excluded by this filter are not included "as is" in the build mesh.

Returns

The point mesh.

extractScalarSet()

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

pure virtual

Extracts a scalar set from the input mesh.

For a PER_NODE dataset, the value of each point of the tessellation is calculated by using the shape functions of the input cell and the parametric coordinates of the each tessellated point. For a PER_CELL dataset, the value of each tessellated cell is just a copy of the value of each input cell. The scalars are mapped onto the current tessellated mesh refering to either the surface mesh, the line mesh or the point mesh depending on whether tessellate(), tessellateLine() or extractPoints() was last called.

Parameters

[in]

inputSet

the input scalar set defined on the input mesh.

Returns

the output scalar set defined on the tessellated mesh.

extractVec3Set()

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

pure virtual

Extracts a vector set from the input mesh.

For a PER_NODE dataset, the value of each point of the tessellation is calculated by using the shape functions of the input cell and the parametric coordinates of the each tessellated point. For a PER_CELL dataset, the value of each tessellated cell is just a copy of the value of each input cell. The vectors are mapped onto the current tessellated mesh refering to either the surface mesh, line mesh or the point mesh depending on whether tessellate(), tessellateLine() or extractPoints() was last called.

Parameters

[in]

inputSet

the input vector set defined on the input mesh.

Returns

the output vector set defined on the tessellated mesh.

getExtract()

virtual const MeXSurfaceMeshUnstructured & MiTessellatedSurfaceExtract::getExtract ( ) const

pure virtual

Returns the tessellated mesh extracted by the previous call to tessellate().

getLineExtract()

virtual const MeXLineMeshUnstructured & MiTessellatedSurfaceExtract::getLineExtract ( ) const

pure virtual

Returns the result of the extraction as a line mesh.

getNewInstance()

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

getPointExtract()

virtual const MeXPointMeshCurvilinear & MiTessellatedSurfaceExtract::getPointExtract ( ) const

pure virtual

Returns the result of the extraction as a point mesh.

tessellate()

virtual const MeXSurfaceMeshUnstructured & MiTessellatedSurfaceExtract::tessellate ( MiTessellator &  tesselator, const MiCellFilterI *  cellFilter = NULL  )

pure virtual

Builds a new linear surface mesh by tessellating each non linear cell of the input mesh given to the factory method getNewInstance().

Parameters

[in]	tesselator	The instance used to tessellate.
[in]	cellFilter	The optional cell filter. surface cells excluded by this filter are neither tessellated nor included "as is" in the build mesh.

Returns

The tessellated mesh.

tessellateLine()

virtual const MeXLineMeshUnstructured & MiTessellatedSurfaceExtract::tessellateLine ( MiTessellator &  tesselator, const MiCellFilterI *  cellFilter = NULL  )

pure virtual

Builds a new linear line mesh by tessellating each non linear cell contour of the input mesh given to the factory method getNewInstance().

Parameters

[in]	tesselator	The instance used to tessellate.
[in]	cellFilter	The optional cell filter. surface cells excluded by this filter are neither tessellated nor included "as is" in the build mesh.

Returns

The tessellated mesh.
