Detailed Description

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.

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.

Parameters:

	rbegin	the smallest cell indices (i,j,k) in the range.
	rend	the 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.

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.

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:

inputSet

the input scalar set defined on the volume mesh

Returns:

the output scalar set defined on the resulting surface mesh

Implemented in MiSkinExtractUnstructuredIjk.

virtual const MeXSurfaceMeshUnstructured& MiSkinExtractIjk::extractSkin

(

const MiCellFilterIjk *

cellFilter = NULL

)

[pure virtual]

Builds the topology and geometry of a mesh skin.

Parameters:

cellFilter

The cell filter.

Returns:

The skin extracted as an unstructured surface mesh.

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:

inputSet

the input vec3 set defined on the volume mesh

Returns:

the output scalar set defined on the resulting surface mesh

Implemented in MiSkinExtractUnstructuredIjk.

virtual const MeXSurfaceMeshUnstructured& MiSkinExtractIjk::getExtract

(

)

const [pure virtual]

Returns the result of the extraction as a mesh.

static MiSkinExtractIjk* MiSkinExtractIjk::getNewInstance	(	const MiVolumeMeshVertexHexahedronIjk &	mesh,

	)			[static]

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

Parameters:

	mesh	The input mesh
