Constructor.
void GetBounds(const double *sizeChild, double bounds[6]) const
Getter for bounding box of the current cell.
void SubdivideLeaf(const vtkHyperTreeGrid *grid, vtkHyperTree *tree, unsigned int level)
Change the current cell's status: if leaf then becomes coarse and all its children are created,...
double * GetOrigin()
Getter for origin coordinates of the current cell.
void SetGlobalIndexStart(vtkHyperTree *tree, vtkIdType index)
Set the global index for the root cell of the HyperTree.
void Dump(ostream &os)
Dump information.
vtkHyperTreeGridGeometryEntry(vtkIdType index, const double *origin)
Constructor.
void PrintSelf(ostream &os, vtkIndent indent)
Display info about the entry.
bool IsRoot() const
Is the cursor at tree root?
void SetGlobalIndexFromLocal(vtkHyperTree *tree, vtkIdType index)
Set the global index for the current cell of the HyperTree.
vtkIdType GetVertexId() const
Return the index of the current vertex in the tree.
bool IsLeaf(const vtkHyperTreeGrid *grid, const vtkHyperTree *tree, unsigned int level) const

~vtkHyperTreeGridGeometryEntry()=default
Destructor.
void Initialize(vtkIdType index, const double *origin)
Initialize cursor from explicit required data.
bool IsMasked(const vtkHyperTreeGrid *grid, const vtkHyperTree *tree) const

vtkHyperTree * Initialize(vtkHyperTreeGrid *grid, vtkIdType treeIndex, bool create=false)
Initialize cursor at root of given tree index in grid.
void Copy(const vtkHyperTreeGridGeometryEntry *entry)
Copy function.
vtkIdType GetGlobalNodeIndex(const vtkHyperTree *tree) const
Return the global index (relative to the grid) of the current vertex in the tree.
void SetMask(const vtkHyperTreeGrid *grid, const vtkHyperTree *tree, bool state)
Set the blanking mask is empty or not.
bool IsTerminalNode(const vtkHyperTreeGrid *grid, const vtkHyperTree *tree, unsigned int level) const
