Detailed Description

template<typename GridT>
class nanovdb::NodeManager< GridT >

NodeNanager maintains separate linear arrays of the three nodes types.

This host class allows for sequential access to nodes in a NanoVDB tree.

Nodes are stored breadth first to allow for sequential access of nodes at a particular level.
