abstract class to specify cell behavior
Definition vtkCell.h:58
virtual bool InsideCellBounds(double x[3], vtkIdType cellId)=0
Quickly test if a point is inside the bounds of a particular cell.
void PrintSelf(ostream &os, vtkIndent indent) override
Standard methods for type information and printing.
virtual void CopyParameters(vtkFindCellStrategy *from)
Copy essential parameters between instances of this class.
virtual vtkIdType FindCell(double x[3], vtkCell *cell, vtkGenericCell *gencell, vtkIdType cellId, double tol2, int &subId, double pcoords[3], double *weights)=0
Virtual method for finding a cell.
virtual int Initialize(vtkPointSet *ps)
All subclasses of this class must provide an initialize method.
~vtkFindCellStrategy() override
virtual vtkIdType FindClosestPointWithinRadius(double x[3], double radius, double closestPoint[3], vtkGenericCell *cell, vtkIdType &cellId, int &subId, double &dist2, int &inside)=0
Return the closest point within a specified radius and the cell which is closest to the point x.
