Detailed Description

MeshViz Streamline extractor for unstructured volume meshes.

Builds a list of MiLineMeshCurvilinear interfaces containing streamlines starting from a list of source points and probes the input mesh to compute the values at the streamline nodes (See MiPointProbeUnstructured for settings).
A streamline is a line that is everywhere tangent to a vector field. Streamlines are meaningless for unsteady flow, because time is not taken into account during the computation of the line. Streamlines are integrated from a given set of vectors using a Runge/Kutta method of order 2 .

virtual const std::vector< const MeXScalardSetI* >& MiStreamlineExtractUnstructured::extractScalarSet ( const MiScalardSetI inputSet  )  [pure virtual]

Extracts from the mesh a list of scalar sets. The scalars are mapped onto the current extracted streamlines. If the dataset is binded PER_NODE the scalars are interpolated and one scalar is binded per node of the extracted streamlines. Otherwise one scalar is binded per edge of the extracted streamlines.

Parameters:
inputSet the input scalar set defined on the original volume mesh
Returns:
the output scalar sets defined on the resulting edge meshes

virtual const std::vector<const MeXLineMeshCurvilinear*>& MiStreamlineExtractUnstructured::extractStreamline ( const MiVec3dSetI inputDataSet,
const std::vector< MbVec3d > &  startPoints,
const MiCellFilterI cellFilter = NULL 
) [pure virtual]

Builds the topology and geometry of the streamlines starting at the given points in the given dataset.

The resulting streamlines can be retrieved by calling getExtract().

Parameters:
inputDataSet Defines the vector field for the streamlines integration
startPoints Defines the list of start points for the streamlines integration
cellFilter The cell filter
Returns:
the extracted streamlines as curvilinear line meshes
virtual const std::vector< const MeXVec3dSetI* >& MiStreamlineExtractUnstructured::extractVec3Set ( const MiVec3dSetI inputSet  )  [pure virtual]

Extracts from the mesh a vector set. The vectors are mapped onto the current extracted streamlines. If the dataset is binded PER_NODE the vectors are interpolated and one vector is binded per node of the extracted streamlines. Otherwise one vector is binded per edge of the extracted streamlines.

Parameters:
inputSet the input vector set defined on the original volume mesh
Returns:
the output scalar sets defined on the resulting edge meshes

virtual const std::vector<const MeXLineMeshCurvilinear*>& MiStreamlineExtractUnstructured::getExtract (  )  const [pure virtual]

Returns the result of the extraction as a mesh.
