Detailed Description

Generates surface of a CTH volume fraction.

vtkExtractCTHPart is a filter that is specialized for creating visualizations for a CTH simulation. CTH datasets comprise of either vtkNonOverlappingAMR or a multiblock of non-overlapping rectilinear grids with cell-data. Certain cell-arrays in the dataset identify the fraction of a particular material present in a given cell. This goal with this filter is to extract a surface contour demarcating the surface where the volume fraction for a particular material is equal to the user chosen value.

To achieve that, this filter first converts the cell-data to point-data and then simply apply vtkContourFilter filter to extract the contour.

vtkExtractCTHPart also provides the user with an option to clip the resultant contour using a vtkPlane. Internally, it uses vtkClipClosedSurface to clip the contour using the vtkPlane provided.

The output of this filter is a vtkMultiBlockDataSet with one block corresponding to each volume-fraction array requested. Each block itself is a vtkPolyData for the contour generated on the current process (which may be null, for processes where no contour is generated).

Member Function Documentation

static vtkExtractCTHPart* vtkExtractCTHPart::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkMultiBlockDataSetAlgorithm.

static int vtkExtractCTHPart::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkMultiBlockDataSetAlgorithm.

virtual int vtkExtractCTHPart::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

void vtkExtractCTHPart::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
