Overwrite each inactive value in this node and in any child nodes with a new value whose magnitude is equal to the specified background value and whose sign is consistent with that of the lexicographically closest active value.
This is primarily useful for propagating the sign from the (active) voxels in a narrow-band level set to the inactive voxels outside the narrow band.
Overwrite each inactive value in this node and in any child nodes with either outside or inside, depending on the sign of the lexicographically closest active value.
Specifically, an inactive value is set to outside if the closest active value in the lexicographic direction is positive, otherwise it is set to inside.

Exchange this node's data buffer with the given data buffer without changing the active states of the values.
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 LeafNode and inactive in the other LeafNode.
The last dummy argument is required to match the signature for InternalNode::topologyDifference.

Intersect this node's set of active values with the active values of the other node, whose ValueType
