Detailed Description

template<typename T, Index Log2Dim>
class openvdb::v12_0::tree::LeafNode< T, Log2Dim >

Templated block class to hold specific data types and a fixed number of values determined by Log2Dim. The actual coordinate dimension of the block is 2^Log2Dim, i.e. Log2Dim=3 corresponds to a LeafNode that spans a 8^3 block.
