Detailed Description

Remove overlapped cells from a given unstructured surface mesh or a list of meshes.

This tool is another type of extractor which takes an unstructured surface mesh as input and produces a new surface mesh where overlapped cells are discarded. We define an overlapped cell as a cell lying on the same plane as a set of cells which are entirely hiding this cell. In the output mesh, the geometry refers to the input geometry and the topology refers to the input topology, except that the overlapped cells are set as "dead cells".

This tool can also work on a list of unstructured surface meshes. In that case, it merges all of them into an output mesh, using the original geometries and topologies where overlapped cells from all input meshes are set as dead. To work on a list of surface meshes, call getNewInstance(const std::vector<const MiSurfaceMeshUnstructured*>&, bool).

To detach the resulting mesh from the input meshes, it must be cloned (see MeXSurfaceMeshUnstructured::getNewClone()).

The following example shows how to remove overlapped cells in a list of meshes:

MiNonOverlappedCellsExtractUnstructured* extract =
  MiNonOverlappedCellsExtractUnstructured::getNewInstance(meshList);
const MeXScalardSetI& scalarSet = extract->extractScalarSet(scalarSets);
const MeXVec3dSetI& vectorSet = extract->extractVec3Set(vectorSets);

Member Function Documentation

extractScalarSet() [1/2]

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

pure virtual

Extracts a scalar set from the original mesh.

The scalars are mapped onto the current extracted mesh.

Parameters

inputSet

The input scalar set defined on the original mesh.

Returns

The output scalar set defined on the extracted mesh. This method must not be called when the extractor is working on a list of meshes. (.ie. the extractor has been built by getNewInstance(const std::vector<const MiSurfaceMeshUnstructured*>&, bool))

extractScalarSet() [2/2]

virtual const MeXScalardSetI & MiNonOverlappedCellsExtractUnstructured::extractScalarSet ( const std::vector< const MiScalardSetI * > &  scalarSets )

pure virtual

extractSurface() [1/2]

virtual const MeXSurfaceMeshUnstructured & MiNonOverlappedCellsExtractUnstructured::extractSurface ( const MiCellFilterI *  cellFilter = NULL )

pure virtual

Builds the topology and geometry of the surface mesh after removing all overlapped cells.

This method must not be called when the extractor is working on a list of meshes. (.ie. the extractor has been built by getNewInstance(const std::vector<const MiSurfaceMeshUnstructured*>&, bool))

extractSurface() [2/2]

virtual const MeXSurfaceMeshUnstructured & MiNonOverlappedCellsExtractUnstructured::extractSurface ( const std::vector< const MiCellFilterI * > *  cellFilters )

pure virtual

Builds the topology and geometry of the surface mesh after removing all overlapped cells.

The resulting mesh is made of all cells of the input meshes but those overlapped.

Parameters

cellFilters

list that must contain same number of cell filters as the number of input meshes in getNewInstance(const std::vector<const MiSurfaceMeshUnstructured*>&, bool)

extractVec3Set() [1/2]

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

pure virtual

Extracts a vector set from the original mesh.

The vectors are mapped onto the current extracted mesh.

Parameters

inputSet

The input vector set defined on the original mesh.

Returns

The output vector set defined on the extracted mesh. This method must not be called when the extractor is working on a list of meshes. (.ie. the extractor has been built by getNewInstance(const std::vector<const MiSurfaceMeshUnstructured*>&, bool))

extractVec3Set() [2/2]

virtual const MeXVec3dSetI & MiNonOverlappedCellsExtractUnstructured::extractVec3Set ( const std::vector< const MiVec3dSetI * > &  vec3Sets )

pure virtual

Extracts a vector set from the list of meshes.

The vectors are mapped onto the current extracted mesh.

Parameters

vec3Sets

list that must contain same number of vector sets as the number of input meshes in getNewInstance(const std::vector<const MiSurfaceMeshUnstructured*>&, bool)

getExtract()

virtual const MeXSurfaceMeshUnstructured & MiNonOverlappedCellsExtractUnstructured::getExtract ( ) const

pure virtual

Returns the result of the extraction as a mesh.

getNewInstance() [1/2]

static MiNonOverlappedCellsExtractUnstructured * MiNonOverlappedCellsExtractUnstructured::getNewInstance ( const MiSurfaceMeshUnstructured &  mesh, bool  parallel = true  )

static
