| | TreeToMerge (const TreeType &tree, DeepCopy, bool initialize=true) |
| | Const tree pointer constructor for deep-copying data. As the tree is not mutable and thus cannot be pruned, a lightweight mask tree with the same topology is created that can be pruned to use as a reference. Initialization of this mask tree can optionally be disabled for delayed construction. More...

| | TreeToMerge (TreeType &tree, DeepCopy tag, bool initialize=true) |
| | Non-const tree pointer constructor for deep-copying data. The tree is not intended to be modified so is not pruned, instead a lightweight mask tree with the same topology is created that can be pruned to use as a reference. Initialization of this mask tree can optionally be disabled for delayed construction. More...

template<typename TreeT>
struct openvdb::OPENVDB_VERSION_NAME::tools::TreeToMerge< TreeT >
Convenience class that contains a pointer to a tree to be stolen or deep copied depending on the tag dispatch class used and a subset of methods to retrieve data from the tree.
The primary purpose of this class is to be able to create an array of TreeToMerge objects that each store a tree to be stolen or a tree to be deep-copied in an arbitrary order. Certain operations such as floating-point addition are non-associative so the order in which they are merged is important for the operation to remain deterministic regardless of how the data is being extracted from the tree.
- Note
- Stealing data requires a non-const tree pointer. There is a constructor to pass in a tree shared pointer for cases where it is desirable for this class to maintain shared ownership.

Return a pointer to the node of type NodeT that contains voxel (x, y, z). If the tree is non-const, steal the node and replace it with the value provided. If the tree is const, deep-copy the node and modify the mask tree to prune the node.
