Detailed Description
cut a vtkGenericDataSet with an implicit function or scalar data
vtkGenericCutter is a filter to cut through data using any subclass of vtkImplicitFunction. That is, a polygonal surface is created corresponding to the implicit function F(x,y,z) = value(s), where you can specify one or more values used to cut with.
In VTK, cutting means reducing a cell of dimension N to a cut surface of dimension N-1. For example, a tetrahedron when cut by a plane (i.e., vtkPlane implicit function) will generate triangles. (In comparison, clipping takes a N dimensional cell and creates N dimension primitives.)
vtkGenericCutter is generally used to "slice-through" a dataset, generating a surface that can be visualized. It is also possible to use vtkGenericCutter to do a form of volume rendering. vtkGenericCutter does this by generating multiple cut surfaces (usually planes) which are ordered (and rendered) from back-to-front. The surfaces are set translucent to give a volumetric rendering effect.
This filter has been implemented to operate on generic datasets, rather than the typical vtkDataSet (and subclasses). vtkGenericDataSet is a more complex cousin of vtkDataSet, typically consisting of nonlinear, higher-order cells. To process this type of data, generic cells are automatically tessellated into linear cells prior to isocontouring.

Member Function Documentation
| static int vtkGenericCutter::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 vtkGenericCutter::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.
Reimplemented from vtkPolyDataAlgorithm.
| static vtkGenericCutter* vtkGenericCutter::SafeDownCast | ( | vtkObjectBase * | o | ) | [static] |

| void vtkGenericCutter::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 vtkGenericCutter* vtkGenericCutter::New | ( | ) | [static] |
Construct with user-specified implicit function; initial value of 0.0; and generating cut scalars turned off.
Reimplemented from vtkPolyDataAlgorithm.
| void vtkGenericCutter::SetValue | ( | int | i, |
| double | value | ||
| ) |
Set a particular contour value at contour number i. The index i ranges between 0<=i<NumberOfContours.
Get the ith contour value.
Get a pointer to an array of contour values. There will be GetNumberOfContours() values in the list.
| void vtkGenericCutter::GetValues | ( | double * | contourValues | ) |
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.
| void vtkGenericCutter::SetNumberOfContours | ( | int | number | ) |
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.
Get the number of contours in the list of contour values.
| void vtkGenericCutter::GenerateValues | ( | int | numContours, |
| double | range[2] | ||
| ) |
Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values.
| void vtkGenericCutter::GenerateValues | ( | int | numContours, |
| double | rangeStart, | ||
| double | rangeEnd | ||
| ) |
Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values.
| unsigned long vtkGenericCutter::GetMTime | ( | ) | [virtual] |
Override GetMTime because we delegate to vtkContourValues and refer to vtkImplicitFunction.
Reimplemented from vtkObject.
| virtual void vtkGenericCutter::SetCutFunction | ( | vtkImplicitFunction * | ) | [virtual] |
Specify the implicit function to perform the cutting.
| virtual vtkImplicitFunction* vtkGenericCutter::GetCutFunction | ( | ) | [virtual] |
Specify the implicit function to perform the cutting.
| virtual void vtkGenericCutter::SetGenerateCutScalars | ( | int | ) | [virtual] |
If this flag is enabled, then the output scalar values will be interpolated from the implicit function values, and not the input scalar data.
| virtual int vtkGenericCutter::GetGenerateCutScalars | ( | ) | [virtual] |
If this flag is enabled, then the output scalar values will be interpolated from the implicit function values, and not the input scalar data.
| virtual void vtkGenericCutter::GenerateCutScalarsOn | ( | ) | [virtual] |
If this flag is enabled, then the output scalar values will be interpolated from the implicit function values, and not the input scalar data.
| virtual void vtkGenericCutter::GenerateCutScalarsOff | ( | ) | [virtual] |
If this flag is enabled, then the output scalar values will be interpolated from the implicit function values, and not the input scalar data.
| void vtkGenericCutter::SetLocator | ( | vtkIncrementalPointLocator * | locator | ) |
Specify a spatial locator for merging points. By default, an instance of vtkMergePoints is used.
| virtual vtkIncrementalPointLocator* vtkGenericCutter::GetLocator | ( | ) | [virtual] |
Specify a spatial locator for merging points. By default, an instance of vtkMergePoints is used.
Create default locator. Used to create one when none is specified. The locator is used to merge coincident points.
