Detailed Description

Interface for all vtkHyperTreeGridGeometry internal classes.

This class defines the common interface of all vtkHyperTreeGridGeometry internal classes. The role of these classes is to perform the actual generation of the external surface (geometry) of the input vtkHyperTreeGrid.

The code is split into specific internal classes depending on the dimension of the input HTG. Each class implement the pure virtual GenerateGeometry method, that achieve the construction of the HTG surface.

Member Function Documentation

GenerateGeometry()

virtual void vtkHyperTreeGridGeometryImpl::GenerateGeometry ( )

pure virtual

Generate the external surface of the input vtkHyperTreeGrid.

This method is implemented by subclasses, depending on the dimension of the HTG.

Implemented in vtkHyperTreeGridGeometry3DImpl, and vtkHyperTreeGridGeometrySmallDimensionsImpl.

ComputeDistanceToInterfaceA()

double vtkHyperTreeGridGeometryImpl::ComputeDistanceToInterfaceA ( const double *  xyz ) const

protected

Compute the value of the distance from the given point to the interface plane of the currently considered HTG cell.

A and B refers to the two interfaces that can cut the HTG cell.

XXX: The value returned by this function depends on the actual values of CellIntercepts and CellNormals.

ComputeDistanceToInterfaceB()

double vtkHyperTreeGridGeometryImpl::ComputeDistanceToInterfaceB ( const double *  xyz ) const

protected

Compute the value of the distance from the given point to the interface plane of the currently considered HTG cell.

A and B refers to the two interfaces that can cut the HTG cell.

XXX: The value returned by this function depends on the actual values of CellIntercepts and CellNormals.

CreateNewCellAndCopyData()

void vtkHyperTreeGridGeometryImpl::CreateNewCellAndCopyData ( const std::vector< vtkIdType > &  outPointIds, vtkIdType  cellId  )

protected

Insert a new output cell from a list of point ids in the output polydata and copy the data from the input HTG cell at cellId to the newly created surface cell.

IsMaskedOrGhost()

bool vtkHyperTreeGridGeometryImpl::IsMaskedOrGhost ( vtkIdType  globalNodeId ) const

protected

Returns true if the input HTG cell is masked or ghosted.

ProbeForCellInterface()

bool vtkHyperTreeGridGeometryImpl::ProbeForCellInterface ( vtkIdType  cellId, bool  invert = true  )

protected

Determine if the input HTG at cellId contains an valid interface and if yes, determine its characteristics, stored in the variables below.

Returns true in case of a "valid" interface description.

XXX: Populates:

• HasInterfaceOnThisCell
• CellInterfaceType
• CellNormals
• CellIntercepts
