Detailed Description

clip volume data with user-specified implicit function or input scalar data

vtkClipVolume is a filter that clips volume data (i.e., vtkImageData) using either: any subclass of vtkImplicitFunction or the input scalar data. The clipping operation cuts through the cells of the dataset–converting 3D image data into a 3D unstructured grid–returning everything inside of the specified implicit function (or greater than the scalar value). During the clipping the filter will produce pieces of a cell. (Compare this with vtkExtractGeometry or vtkGeometryFilter, which produces entire, uncut cells.) The output of this filter is a 3D unstructured grid (e.g., tetrahedra or other 3D cell types).

To use this filter, you must decide if you will be clipping with an implicit function, or whether you will be using the input scalar data. If you want to clip with an implicit function, you must first define and then set the implicit function with the SetClipFunction() method. Otherwise, you must make sure input scalar data is available. You can also specify a scalar value, which is used to decide what is inside and outside of the implicit function. You can also reverse the sense of what inside/outside is by setting the InsideOut instance variable. (The cutting algorithm proceeds by computing an implicit function value or using the input scalar data for each point in the dataset. This is compared to the scalar value to determine inside/outside.)

This filter can be configured to compute a second output. The second output is the portion of the volume that is clipped away. Set the GenerateClippedData boolean on if you wish to access this output data.

The filter will produce an unstructured grid of entirely tetrahedra or a mixed grid of tetrahedra and other 3D cell types (e.g., wedges). Control this behavior by setting the Mixed3DCellGeneration. By default the Mixed3DCellGeneration is on and a combination of cell types will be produced. Note that producing mixed cell types is a faster than producing only tetrahedra.

Warning: This filter is designed to function with 3D structured points. Clipping 2D images should be done by converting the image to polygonal data and using vtkClipPolyData,

Reimplemented from vtkUnstructuredGridAlgorithm.

static vtkClipVolume* vtkClipVolume::New ( )

static

Construct with user-specified implicit function; InsideOut turned off; value set to 0.0; and generate clip scalars turned off.

Set the clipping value of the implicit function (if clipping with implicit function) or scalar value (if clipping with scalars). The default value is 0.0.

virtual void vtkClipVolume::SetInsideOut ( int )

Set/Get the InsideOut flag. When off, a vertex is considered inside the implicit function if its value is greater than the Value ivar. When InsideOutside is turned on, a vertex is considered inside the implicit function if its implicit function value is less than or equal to the Value ivar. InsideOut is off by default.

virtual int vtkClipVolume::GetInsideOut ( )

virtual

Set/Get the InsideOut flag. When off, a vertex is considered inside the implicit function if its value is greater than the Value ivar. When InsideOutside is turned on, a vertex is considered inside the implicit function if its implicit function value is less than or equal to the Value ivar. InsideOut is off by default.

virtual void vtkClipVolume::InsideOutOn ( )

virtual

Set/Get the InsideOut flag. When off, a vertex is considered inside the implicit function if its value is greater than the Value ivar. When InsideOutside is turned on, a vertex is considered inside the implicit function if its implicit function value is less than or equal to the Value ivar. InsideOut is off by default.

virtual void vtkClipVolume::InsideOutOff ( )

virtual

Set/Get the InsideOut flag. When off, a vertex is considered inside the implicit function if its value is greater than the Value ivar. When InsideOutside is turned on, a vertex is considered inside the implicit function if its implicit function value is less than or equal to the Value ivar. InsideOut is off by default.

virtual void vtkClipVolume::SetClipFunction ( vtkImplicitFunction * )

virtual

Specify the implicit function with which to perform the clipping. If you do not define an implicit function, then the input scalar data will be used for clipping.

virtual

Specify the implicit function with which to perform the clipping. If you do not define an implicit function, then the input scalar data will be used for clipping.

virtual void vtkClipVolume::SetGenerateClipScalars ( 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. If you enable this flag but do not provide an implicit function an error will be reported.
