inline

Return a pointer to the node of type NodeT that contains voxel (x, y, z) and replace it with a tile of the specified value and state. If no such node exists, leave the tree unchanged and return nullptr.

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 subsequnetly 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 unactive 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)

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

Return the leaf node that contains voxel (x, y, z). If no such node exists, create one, but preserve the values and active states of all voxels.

Use this method to preallocate a static tree topology over which to safely perform multithreaded processing.

LeafNodeType* touchLeafAndCache ( const Coord &  xyz,
AccessorT &

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