| InternalNode.h |
| Internal table nodes for OpenVDB trees.

| Iterator.h |
|
| LeafBuffer.h |
|
| LeafManager.h |
| A LeafManager manages a linear array of pointers to a given tree's leaf nodes, as well as optional auxiliary buffers (one or more per leaf) that can be swapped with the leaf nodes' voxel data buffers.

|
| NodeManager.h |
| NodeManager produces linear arrays of all tree nodes allowing for efficient threading and bottom-up processing.

| NodeUnion.h |
|
| RootNode.h |
| The root node of an OpenVDB tree.

|
| ValueAccessor.h |
| ValueAccessors are designed to help accelerate accesses into the OpenVDB Tree structures by storing caches to Tree branches. When traversing a grid in a spatially coherent pattern (e.g., iterating over neighboring voxels), the same branches and nodes of the underlying tree can be hit. If you do this using the Tree/RootNode methods directly, traversal will occur at O(log(n)) (or O(n) depending on the hash map implementation) for every access. However, using a ValueAccessor allows for the Accessor to cache previously visited Nodes, providing possible subsequent access speeds of O(1) if the next access is close to a previously cached Node. Accessors are lightweight and can be configured to cache any number of arbitrary Tree levels.
