## Member Function Documentation

virtual const char* vtkApproximatingSubdivisionFilter::GetClassName | ( |  | ) | `[virtual]`

| Reimplemented from vtkPolyDataToPolyDataFilter. Reimplemented in vtkLoopSubdivisionFilter.

int vtkApproximatingSubdivisionFilter::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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataToPolyDataFilter. Reimplemented in vtkLoopSubdivisionFilter.

virtual int vtkApproximatingSubdivisionFilter::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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataToPolyDataFilter. Reimplemented in vtkLoopSubdivisionFilter.

vtkApproximatingSubdivisionFilter* vtkApproximatingSubdivisionFilter::SafeDownCast | ( | vtkObject * | o | ) | `[static]`

| Reimplemented from vtkPolyDataToPolyDataFilter. Reimplemented in vtkLoopSubdivisionFilter.

void vtkApproximatingSubdivisionFilter::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 vtkPolyDataToPolyDataFilter.

virtual void vtkApproximatingSubdivisionFilter::SetNumberOfSubdivisions | ( | int |  | ) | `[virtual]`

| Set/get the number of subdivisions.

virtual int vtkApproximatingSubdivisionFilter::GetNumberOfSubdivisions | ( |  | ) | `[virtual]`

| Set/get the number of subdivisions.

void vtkApproximatingSubdivisionFilter::Execute | ( |  | ) | `[protected, virtual]`

| This method is the old style execute method Reimplemented from vtkSource.

virtual void vtkApproximatingSubdivisionFilter::GenerateSubdivisionPoints | ( | vtkPolyData * | inputDS,
|  | vtkIntArray * | edgeData,
|  | vtkPoints * | outputPts,
|  | vtkPointData * | outputPD
| ) | `[protected, pure virtual]`

| Implemented in vtkLoopSubdivisionFilter.

void vtkApproximatingSubdivisionFilter::GenerateSubdivisionCells | ( | vtkPolyData * | inputDS,
|  | vtkIntArray * | edgeData,
|  | vtkCellArray * | outputPolys,
|  | vtkCellData * | outputCD
| ) | `[protected]`

int vtkApproximatingSubdivisionFilter::FindEdge | ( | vtkPolyData * | mesh,
|  | vtkIdType | cellId,
|  | vtkIdType | p1,
|  | vtkIdType | p2,
|  | vtkIntArray * | edgeData,
|  | vtkIdList * | cellIds
| ) | `[protected]`

vtkIdType vtkApproximatingSubdivisionFilter::InterpolatePosition | ( | vtkPoints * | inputPts,
|  | vtkPoints * | outputPts,
|  | vtkIdList * | stencil,
