Member Function Documentation

bool addChild ( ChildNodeType * child )

inline

Add the given child node at this level deducing the offset from it's origin. If a child node with this offset already exists, delete the old node and add the new node in its place (i.e. ownership of the new child node is transferred to this InternalNode)

Returns: true if inserting the child has been successful, otherwise the caller retains ownership of the node and is responsible for deleting it.

void addLeaf ( LeafNodeType * leaf )

inline

Add the specified leaf to this node, possibly creating a child branch in the process. If the leaf node already exists, replace it.

void addLeafAndCache	(	LeafNodeType *	leaf,
		AccessorT &	acc
	)

inline

Same as addLeaf() except, if necessary, update the accessor with pointers to the nodes along the path from the root node to the node containing the coordinate.

void addTile	(	Index	level,
		const Coord &	xyz,
		const ValueType &	value,
		bool	state
	)

inline

Add a tile at the specified tree level that contains voxel (x, y, z), possibly creating a parent branch or deleting a child branch in the process.

Note: The caller takes ownership of the node and is responsible for deleting it.

Warning: Since this method potentially removes nodes and branches of the tree, it is important to clear the caches of all ValueAccessors associated with this tree.

void stealNodes	(	ArrayT &	array,
		const ValueType &	value,
		bool	state
	)

inline

Steals all nodes of a certain type from the tree and adds them to a container with the following API:

struct ArrayT {
   using value_type = ...;// defines the type of nodes to be added to the array
   void push_back(value_type nodePtr);// method that add nodes to the array
};

An example of a wrapper around a c-style array is:

 struct MyArray {
    using value_type = LeafType*;
    value_type* ptr;
    MyArray(value_type* array) : ptr(array) {}
    void push_back(value_type leaf) { *ptr++ = leaf; }
};

An example that constructs a list of pointer to all leaf nodes is:

std::vector<const LeafNodeType*> array;//most std contains have the required API
array.reserve(tree.leafCount());//this is a fast preallocation.
tree.stealNodes(array);

void topologyDifference	(	const InternalNode< OtherChildNodeType, Log2Dim > &	other,
		const ValueType &	background
	)

Difference this node's set of active values with the active values of the other node, whose ValueType may be different. So a resulting voxel will be active only if the original voxel is active in this node and inactive in the other node.

The last dummy argument is required to match the signature for InternalNode::topologyDifference.

Note: This operation modifies only active states, not values. Also note that this operation can result in all voxels being inactive so consider subsequently calling prune.

void topologyDifference	(	const InternalNode< OtherChildT, Log2Dim > &	other,
		const ValueType &	background
	)

inline

void topologyIntersection	(	const InternalNode< OtherChildNodeType, Log2Dim > &	other,
		const ValueType &	background
	)

Intersects this tree's set of active values with the active values of the other tree, whose ValueType may be different.

The resulting state of a value is active only if the corresponding value was already active AND if it is active in the other tree. Also, a resulting value maps to a voxel if the corresponding value already mapped to an active voxel in either of the two grids and it maps to an active tile or voxel in the other grid.

Note: This operation can delete branches in this grid if they overlap with inactive tiles in the other grid. Likewise active voxels can be turned into inactive voxels resulting in leaf nodes with no active values. Thus, it is recommended to subsequently call prune.

void topologyIntersection	(	const InternalNode< OtherChildT, Log2Dim > &	other,
		const ValueType &	background
	)

inline

void topologyUnion	(	const InternalNode< OtherChildNodeType, Log2Dim > &	other,
		const bool	preserveTiles = `false`
	)

Union this branch's set of active values with the other branch's active values. The value type of the other branch can be different.

The resulting state of a value is active if the corresponding value was already active OR if it is active in the other tree. Also, a resulting value maps to a voxel if the corresponding value already mapped to a voxel OR if it is a voxel in the other tree. Thus, a resulting value can only map to a tile if the corresponding value already mapped to a tile AND if it is a tile value in other tree.

Specifically, active tiles and voxels in this branch are not changed, and tiles or voxels that were inactive in this branch but active in the other branch are marked as active in this branch but left with their original values.

void topologyUnion	(	const InternalNode< OtherChildT, Log2Dim > &	other,

ChildT::LeafNodeType * touchLeaf ( const Coord & xyz )
