Detailed Description

MeshViz Sphere slice extractor for structured volume meshes

A sphere slice is the intersection of a given sphere with the mesh volume. The extracted sphere slice is an unstructured surface mesh.

Additional data sets can be mapped onto this extracted surface by calling the extractScalarSet() or extractVec3Set() methods.

The following sample code shows how to extract a sphere slice from a mesh:

MiSphereSliceExtractIjk* sphereSliceExtract =
const MeXSurfaceMeshUnstructured& sphereSlice =
sphereSliceExtract->extractSlice(center,radius, NULL);

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

virtual const MeXSurfaceMeshUnstructured & extractSlice(const MbVec3< double > &center, double radius, const MiCellFilterIjk *cellFilter=NULL)=0
Builds the topology and geometry of a sphere slice intersecting the volume mesh.

◆ extractScalarSet()

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

Extracts a scalar set from the original mesh.

The scalars are mapped onto the current extracted mesh.

Parameters
inputSetThe input scalar set defined on the original mesh.
Returns
The output scalar set defined on the extracted mesh.

Implemented in MiSphereSliceExtractHexahedronIjk.

◆ extractSlice()

virtual const MeXSurfaceMeshUnstructured & MiSphereSliceExtractIjk::extractSlice ( const MbVec3< double > &  center,
double  radius,
const MiCellFilterIjk cellFilter = NULL 
)
pure virtual

Builds the topology and geometry of a sphere slice intersecting the volume mesh.

Parameters
centerThe position of the center of the sphere
radiusThe radius of the sphere
cellFilterThe cell filter object.
Returns
An unstructured surface mesh representing the sphere slice

◆ extractVec3Set()

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

Extracts a vector set from the original mesh.

The vectors are mapped onto the current extracted mesh.

Parameters
inputSetThe input vector set defined on the original mesh.
Returns
The output vector set defined on the extracted mesh.

Implemented in MiSphereSliceExtractHexahedronIjk.

◆ getExtract()

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

Returns the result of the extraction as a mesh.

)
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.
