Detailed Description

Sphere slice extractor for unstructured 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:

MiSphereSliceExtractUnstructured* sphereSliceExtract =
  MiSphereSliceExtractUnstructured::getNewInstance(mesh);
const MeXSurfaceMeshUnstructured& sphereSlice =
  sphereSliceExtract->extractSlice(center,radius, NULL);

extractScalarSet()

virtual const MeXScalardSetI & MiSphereSliceExtractUnstructured::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.

extractSlice()

virtual const MeXSurfaceMeshUnstructured & MiSphereSliceExtractUnstructured::extractSlice ( const MbVec3< double > &  center, double  radius, const MiCellFilterI *  cellFilter = NULL  )

pure virtual

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

Parameters

center	The position of the center of the sphere
radius	The radius of the sphere
cellFilter	The cell filter object.

Returns

An unstructured surface mesh representing the sphere slice

extractVec3Set()

virtual const MeXVec3dSetI & MiSphereSliceExtractUnstructured::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.

getExtract()

virtual const MeXSurfaceMeshUnstructured & MiSphereSliceExtractUnstructured::getExtract ( ) const

pure virtual

Returns the result of the extraction as a mesh.

getNewInstance()

static MiSphereSliceExtractUnstructured * MiSphereSliceExtractUnstructured::getNewInstance ( const MiVolumeMeshUnstructured &  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.
