Detailed Description

Clip any dataset with a user-specified implicit function or an input scalar point data array.

vtkTableBasedClipDataSet is a filter that clips any type of dataset using either any subclass of vtkImplicitFunction or an input scalar point data array. Clipping means that it actually "cuts" through the cells of the dataset, returning everything outside the specified implicit function (or greater than the scalar value) including "pieces" of a cell (Note to compare this with vtkExtractGeometry, which pulls out entire, uncut cells). The output of this filter is a vtkUnstructuredGrid data.

To use this filter, you need to decide whether an implicit function or an input scalar point data array is used for clipping. For the former case, 1) define an implicit function 2) provide it to this filter via SetClipFunction() If a clipping function is not specified, or GenerateClipScalars is off( the default), the input scalar point data array is then employed for clipping.

You can also specify a scalar (iso-)value, which is used to decide what is inside and outside the implicit function. You can also reverse the sense of what inside/outside is by setting IVAR InsideOut. The clipping algorithm proceeds by computing an implicit function value or using the input scalar point data value for each point in the dataset. This is compared against the scalar (iso-)value to determine the inside/outside status.

Although this filter sometimes (but rarely) may resort to the sibling class vtkClipDataSet for handling some special grids (such as cylinders or cones with capping faces in the form of a vtkPolyData), it itself is able to deal with most grids. It is worth mentioning that vtkTableBasedClipDataSet is capable of addressing the artifacts that may occur with vtkClipDataSet due to the possibly inconsistent triangulation modes between neighboring cells. In addition, the former is much faster than the latter. Furthermore, the former produces less cells (with ratio usually being 5~6) than by the latter in the output. In other words, this filter retains the original cells (i.e., without triangulation / tetrahedralization) wherever possible. All these advantages are gained by adopting the unique clipping and triangulation tables proposed by VisIt.

Warning: vtkTableBasedClipDataSet makes use of a hash table (that is provided by class maintained by internal class vtkTableBasedClipperDataSetFromVolume) to achieve rapid removal of duplicate points. The hash-based mechanism simply compares the point Ids, without considering the actual inter-point distance (vtkClipDataSet adopts vtkMergePoints that though considers the inter-point distance for robust points merging ). As a result, some duplicate points may be present in the output. This problem occurs when some boundary (cut-through cells) happen to have faces EXACTLY aligned with the clipping plane (such as Plane, Box, or other implicit functions with planar shapes). The occurrence (though very rare) of duplicate points produces degenerate cells, which can be fixed by post-processing the output with a filter like vtkCleanGrid.

Thanks:: This filter was adapted from the VisIt clipper (vtkVisItClipper).
