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.

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 86 of file vtkHyperOctreeContourFilter.h.

double vtkHyperOctreeContourFilter::GetValue ( int  i)
inline

Get the ith contour value.

Definition at line 94 of file vtkHyperOctreeContourFilter.h.

double* vtkHyperOctreeContourFilter::GetValues ( )
inline

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

Definition at line 103 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 113 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.

Definition at line 123 of file vtkHyperOctreeContourFilter.h.

int vtkHyperOctreeContourFilter::GetNumberOfContours ( )
inline

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

Definition at line 131 of file vtkHyperOctreeContourFilter.h.

void vtkHyperOctreeContourFilter::GenerateValues ( int  numContours,
double  range[2] 
)
inline

Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values.

Definition at line 140 of file vtkHyperOctreeContourFilter.h.

void vtkHyperOctreeContourFilter::GenerateValues ( int  numContours,
double  rangeStart,
double  rangeEnd 
)
inline

Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values.

Definition at line 149 of file vtkHyperOctreeContourFilter.h.

unsigned long vtkHyperOctreeContourFilter::GetMTime ( )

Modified GetMTime Because we delegate to vtkContourValues

void vtkHyperOctreeContourFilter::SetLocator ( vtkIncrementalPointLocator *  locator)

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