Detailed Description

generate isosurface(s) from volume.

Date:
2000/12/10 20:09:16
Revision:
1.43

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.

Member Function Documentation

vtkMarchingCubes* vtkMarchingCubes::New   [static]
 

Instantiate object with no start, end, or progress methods.

Reimplemented from vtkPolyDataSource.

virtual const char* vtkMarchingCubes::GetClassName   [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkStructuredPointsToPolyDataFilter.

int vtkMarchingCubes::IsTypeOf const char *    type [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 vtkStructuredPointsToPolyDataFilter.

virtual int vtkMarchingCubes::IsA const char *    type [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.

Reimplemented from vtkStructuredPointsToPolyDataFilter.

vtkMarchingCubes* vtkMarchingCubes::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkStructuredPointsToPolyDataFilter.

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 vtkSource.

void vtkMarchingCubes::SetValue int    i,
float    value
[inline]
 

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

Definition at line 155 of file vtkMarchingCubes.h.

float vtkMarchingCubes::GetValue int    i [inline]
 

Get the ith contour value.

Definition at line 159 of file vtkMarchingCubes.h.

float * vtkMarchingCubes::GetValues   [inline]
 

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

Definition at line 164 of file vtkMarchingCubes.h.

void vtkMarchingCubes::GetValues float *    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 170 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 176 of file vtkMarchingCubes.h.

int vtkMarchingCubes::GetNumberOfContours   [inline]
 

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

Definition at line 180 of file vtkMarchingCubes.h.

void vtkMarchingCubes::GenerateValues int    numContours,
float    range[2]
[inline]
 

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

Definition at line 185 of file vtkMarchingCubes.h.

void vtkMarchingCubes::GenerateValues int    numContours,
float    rangeStart,
float    rangeEnd
[inline]
 

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

Definition at line 190 of file vtkMarchingCubes.h.

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 int vtkMarchingCubes::GetComputeNormals   [virtual]
 

virtual void vtkMarchingCubes::ComputeNormalsOn   [virtual]
 

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.

virtual int vtkMarchingCubes::GetComputeGradients   [virtual]
 

virtual void vtkMarchingCubes::ComputeGradientsOn   [virtual]
 

virtual void vtkMarchingCubes::ComputeGradientsOff   [virtual]
 

virtual void vtkMarchingCubes::SetComputeScalars int    [virtual]
 

Set/Get the computation of scalars.

virtual int vtkMarchingCubes::GetComputeScalars   [virtual]
 

virtual void vtkMarchingCubes::ComputeScalarsOn   [virtual]
 

virtual void vtkMarchingCubes::ComputeScalarsOff   [virtual]
 

void vtkMarchingCubes::SetLocator vtkPointLocator   locator
 

virtual vtkPointLocator* vtkMarchingCubes::GetLocator   [virtual]
 

void vtkMarchingCubes::CreateDefaultLocator void   
 

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

void vtkMarchingCubes::SetLocator vtkPointLocator   locator [inline]
 

Obsolete method for legacy compatibility. Do not use.

Definition at line 134 of file vtkMarchingCubes.h.

void vtkMarchingCubes::operator= const vtkMarchingCubes &    [inline, protected]
 

Definition at line 142 of file vtkMarchingCubes.h.

void vtkMarchingCubes::Execute   [protected, virtual]
 

Reimplemented from vtkSource.
