Detailed Description

generate isosurfaces/isolines from scalar values

vtkContourFilter is a filter that takes as input any dataset and generates on output isosurfaces and/or isolines. The exact form of the output depends upon the dimensionality of the input data. Data consisting of 3D cells will generate isosurfaces, data consisting of 2D cells will generate isolines, and data with 1D or 0D cells will generate isopoints. Combinations of output type are possible if the input dimension is mixed.

To use this filter you must specify one or more contour values. You can either use the method SetValue() to specify each contour value, or use GenerateValues() to generate a series of evenly spaced contours. It is also possible to accelerate the operation of this filter (at the cost of extra memory) by using a vtkScalarTree. A scalar tree is used to quickly locate cells that contain a contour surface. This is especially effective if multiple contours are being extracted. If you want to use a scalar tree, invoke the method UseScalarTreeOn().

Warning
For unstructured data or structured grids, normals and gradients are not computed. Use vtkPolyDataNormals to compute the surface normals.

virtual const char* vtkHyperOctreeContourFilter::GetClassName ( )
virtual

Reimplemented from vtkPolyDataAlgorithm.

static int vtkHyperOctreeContourFilter::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 vtkPolyDataAlgorithm.

virtual int vtkHyperOctreeContourFilter::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.

static

Reimplemented from vtkPolyDataAlgorithm.

void vtkHyperOctreeContourFilter::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.

Reimplemented from vtkPolyDataAlgorithm.

static vtkHyperOctreeContourFilter* vtkHyperOctreeContourFilter::New ( )
static

Construct object with initial range (0,1) and single contour value of 0.0.

Reimplemented from vtkPolyDataAlgorithm.

void vtkHyperOctreeContourFilter::SetValue ( int  i,
double  value

inline

Methods to set / get contour values.

Set a particular contour value at contour number i. The index i ranges between 0<=i<NumberOfContours.

Definition at line 85 of file vtkHyperOctreeContourFilter.h.

double vtkHyperOctreeContourFilter::GetValue ( int  i)
inline

Get the ith contour value.

Definition at line 93 of file vtkHyperOctreeContourFilter.h.

double* vtkHyperOctreeContourFilter::GetValues ( )

Get a pointer to an array of contour values. There will be GetNumberOfContours() values in the list.

Definition at line 102 of file vtkHyperOctreeContourFilter.h.

void vtkHyperOctreeContourFilter::GetValues ( double *  contourValues)
inline

Fill a supplied list with contour values. There will be GetNumberOfContours() values in the list. Make sure you allocate enough memory to hold the list.

Definition at line 112 of file vtkHyperOctreeContourFilter.h.

void vtkHyperOctreeContourFilter::SetNumberOfContours ( int  number)
inline

Set the number of contours to place into the list. You only really need to use this method to reduce list size. The method SetValue() will automatically increase list size as needed.

int vtkHyperOctreeContourFilter::GetNumberOfContours ( )
inline

Get the number of contours in the list of contour values.

Definition at line 130 of file vtkHyperOctreeContourFilter.h.

virtual

Set / get a spatial locator for merging points. By default, an instance of vtkMergePoints is used.

void vtkHyperOctreeContourFilter::CreateDefaultLocator ( )

Create default locator. Used to create one when none is specified. The locator is used to merge coincident points.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkHyperOctreeContourFilter::FillInputPortInformation ( int  port,
vtkInformation info 
)
protectedvirtual

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.
