Detailed Description

generate isosurface(s) from volume

vtkMarchingCubes is a filter that takes as input a volume (e.g., 3D structured point set) and generates on output one or more isosurfaces. One or more contour values must be specified to generate the isosurfaces. Alternatively, you can specify a min/max scalar range and the number of contours to generate a series of evenly spaced contour values.

Warning:
This filter is specialized to volumes. If you are interested in contouring other types of data, use the general vtkContourFilter. If you want to contour an image (i.e., a volume slice), use vtkMarchingSquares.

static int vtkMarchingCubes::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.

void vtkMarchingCubes::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.

void vtkMarchingCubes::SetValue ( int  i,
double  value 
) [inline]

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

Definition at line 128 of file vtkMarchingCubes.h.

Get the ith contour value.

Definition at line 134 of file vtkMarchingCubes.h.

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

Definition at line 141 of file vtkMarchingCubes.h.

void vtkMarchingCubes::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 149 of file vtkMarchingCubes.h.

void vtkMarchingCubes::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 157 of file vtkMarchingCubes.h.

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

Definition at line 163 of file vtkMarchingCubes.h.

void vtkMarchingCubes::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 170 of file vtkMarchingCubes.h.

void vtkMarchingCubes::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.

unsigned long int vtkMarchingCubes::GetMTime ( ) [virtual]

Return this object's modified time.

Reimplemented from vtkObject.

virtual void vtkMarchingCubes::SetComputeNormals ( int  ) [virtual]

Set/Get the computation of normals. Normal computation is fairly expensive in both time and storage. If the output data will be processed by filters that modify topology or geometry, it may be wise to turn Normals and Gradients off.

virtual void vtkMarchingCubes::ComputeNormalsOff ( ) [virtual]

virtual void vtkMarchingCubes::SetComputeGradients ( int  ) [virtual]

Set/Get the computation of gradients. Gradient computation is fairly expensive in both time and storage. Note that if ComputeNormals is on, gradients will have to be calculated, but will not be stored in the output dataset. If the output data will be processed by filters that modify topology or geometry, it may be wise to turn Normals and Gradients off.

This is called by the superclass. This is the method you should override.

virtual int vtkMarchingCubes::FillInputPortInformation ( int  port,
vtkInformation info 
) [protected, virtual]

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.
