Detailed Description

MeshViz Skin extractor for a structured volume mesh.

Builds an MiSurfaceMeshUnstructured interface containing the mesh skin for the given data set at the given value. The skin of a mesh is made up of all the faces that belong to only one cell. Internal faces of a mesh will not be displayed unless they are adjacent to dead cells.

Note
The skin extraction processing on MiVolumeMeshCurvilinear and MiVolumeMeshVertexHexahedronIjk can be cancelled by setting a MiExtractorCallback, which will throw a MiCancellationException.

Member Function Documentation

◆ addCellRange()

virtual void MiSkinExtractIjk::addCellRange ( MbVec3ui  rbegin,
MbVec3ui  rend 
)
pure virtual

Add a new cell range constraint to iterate over when performing the skin extraction.

Default is to iterate over all cells in the mesh. Adding a new range to the extractor changes its state, thus triggering a new extraction when calling extractSkin() even if the mesh remains the same. Note: For now, only the first added cellrange is considered during the extraction. Further added ones are ignored.

Parameters
rbeginthe smallest cell indices (i,j,k) in the range.
rendthe largest cell indices (i,j,k) in the range (not included in extraction). Note: The value UNDEFINED_ID may be used for any index and is interpreted as the minimum/maximum cell index available in the current mesh for that axis.

◆ clearCellRanges()

virtual void MiSkinExtractIjk::clearCellRanges ( )
pure virtual

Remove all cell ranges previously added.

Clearing all ranges changes the extractor state, thus triggering a new extraction when calling extractSkin() even if the mesh remains the same.

◆ extractScalarSet()

virtual const MeXScalardSetI & MiSkinExtractIjk::extractScalarSet ( const MiScalardSetIjk inputSet)
pure virtual

Extracts a scalar set from the volume mesh.

The scalars are mapped onto the current extracted skin.

Parameters
inputSetthe input scalar set defined on the volume mesh
Returns
the output scalar set defined on the resulting surface mesh

Implemented in MiSkinExtractHexahedronIjk.

◆ extractSkin()

virtual const MeXSurfaceMeshUnstructured & MiSkinExtractIjk::extractSkin ( const MiCellFilterIjk cellFilter = NULL)
pure virtual

Builds the topology and geometry of a mesh skin.

Throws a MiCancellationException if cancelled (see MiExtractorCallback).

Parameters
cellFilterThe cell filter.
Returns
The skin extracted as an unstructured surface mesh.

◆ extractVec3Set()

virtual const MeXVec3dSetI & MiSkinExtractIjk::extractVec3Set ( const MiVec3dSetIjk inputSet)
pure virtual

Extracts a vector set from the volume mesh.

The vectors are mapped onto the current extracted skin.

Parameters
inputSetthe input vec3 set defined on the volume mesh
Returns
the output scalar set defined on the resulting surface mesh

Implemented in MiSkinExtractHexahedronIjk.

◆ getExtract()

virtual const MeXSurfaceMeshUnstructured & MiSkinExtractIjk::getExtract ( ) const
pure virtual

Returns the result of the extraction as a mesh.

MiTessellator tessellator = NULL 
)

◆ getNewInstance() [3/4]

static MiSkinExtractIjk * MiSkinExtractIjk::getNewInstance ( const MiVolumeMeshRegular mesh,
bool  parallel = true,
MiTessellator tessellator = NULL 
)
static

Factory method returning a new instance of a class implementing this interface.

Parameters
meshThe input mesh
parallelWhen true, tries to create an extract module using a parallel algorithm to speed up the extraction.
tessellatorThe tessellator object used for tessellating non linear cells (quadratic,...).
Note
Only some of the extraction algorithms have a parallel implementation.

bool  parallel = true,
MiTessellator tessellator = NULL
