general representation of visualization data
Definition: vtkDataObject.h:60
dynamic, self-adjusting array of double
Generates a structured extent from unstructured.
Superclass for algorithms that produce a hyper tree grid as output.
Objects for traversal a HyperTreeGrid.
A dataset containing a grid of vtkHyperTree instances arranged as a rectilinear grid.
a simple class to control print indentation
Definition: vtkIndent.h:34
Store zero or more vtkInformation instances.
Store vtkAlgorithm input/output information.
Park and Miller Sequence of pseudo random numbers.
Builds a randomized but reproducible vtkHyperTreeGrid.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void SubdivideLeaves(vtkHyperTreeGridNonOrientedCursor *cursor, vtkIdType treeId)
int FillOutputPortInformation(int port, vtkInformation *info) override
Fill the output port information objects for this algorithm.
int RequestData(vtkInformation *req, vtkInformationVector **inInfo, vtkInformationVector *outInfo) override
This is called by the superclass.
