class Accessor

Class to be used to set and get values of a cell of the Grid. It uses caching to speed up computation.

Create an instance of this object with the method VoxelGrid::greateAccessor()

Public Functions

inline Accessor(VoxelGrid &grid)
inline bool setValue(const CoordT &coord, const DataT &value)

setValue of a cell. If the cell did not exist, it is created.

Parameters:

  • coord – coordinate of the cell

  • value – value to set.

Returns:

the previous state of the cell (ON = true).

inline DataT *value(const CoordT &coord, bool create_if_missing = false)

value getter.

Parameters:

coord – coordinate of the cell.

Returns:

return the pointer to the value or nullptr if not set.

inline bool setCellOn(const CoordT &coord, const DataT &default_value = DataT())

setCellOn is similar to setValue, but the value is changed only if the cell has been created, otherwise, the previous value is used.

Parameters:

  • coord – coordinate of the cell.

  • default_value – default value of the cell. Use only if the cell did not exist before.

Returns:

the previous state of the cell (ON = true).

inline bool setCellOff(const CoordT &coord)

setCellOff will disable a cell without deleting its content.

Parameters:

coord – coordinate of the cell.

Returns:

the previous state of the cell (ON = true).

inline const InnerGrid *lastInnerdGrid() const

lastInnerdGrid returns the pointer to the InnerGrid in the cache.

inline const LeafGrid *lastLeafGrid() const

lastLeafGrid returns the pointer to the LeafGrid in the cache.

inline LeafGrid *getLeafGrid(const CoordT &coord, bool create_if_missing = false)

getLeafGrid gets the pointer to the LeafGrid containing the cell. It is the basic class used by setValue() and value().

Parameters:

  • coord – Coordinate of the cell.

  • create_if_missing – if true, create the Root, Inner and Leaf, if not present.
