vtkMarchingSquares is a filter that takes as input a structured points set and generates on output one or more isolines. One or more contour values must be specified to generate the isolines. Alternatively, you can specify a min/max scalar range and the number of contours to generate a series of evenly spaced contour values.
To generate contour lines the input data must be of topological dimension 2 (i.e., an image). If not, you can use the ImageRange ivar to select an image plane from an input volume. This avoids having to extract a plane first (using vtkExtractSubVolume). The filter deals with this by first trying to use the input data directly, and if not a 2D image, then uses the ImageRange ivar to reduce it to an image.
|
Create default locator. Used to create one when none is specified. The locator is used to merge coincident points. |
|
Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values. |

Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values. |
|
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. |
|
Return this object's modified time. Reimplemented from vtkObject. |
|
Get the number of contours in the list of contour values. |
|
Get the ith contour value. |
|
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. |
|
Get a pointer to an array of contour values. There will be GetNumberOfContours() values in the list. |
|
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. |

|
Instantiate object with no start, end, or progress methods. Reimplemented from vtkPolyDataSource. |
|
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. |
|
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. |
|
Set/Get the i-j-k index range which define a plane on which to generate contour lines. Using this ivar it is possible to input a 3D volume directly and then generate contour lines on one of the i-j-k planes, or a portion of a plane. |
|
Obsolete method for legacy compatibility. Do not use. |
|
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. |
|
Set a particular contour value at contour number i. The index i ranges between 0<=i<NumberOfContours. |
