Detailed Description

template<typename LeafNodeType>
struct openvdb::v13_2::HasMultiPassIO< LeafNodeType >

Metafunction that specifies whether a given leaf node, tree, or grid type requires multiple passes to read and write voxel data.

Multi-pass I/O allows leaf nodes to optimize their serialization layout for delayed-load access patterns. Only PointDataLeafNode supports multi-pass I/O. Defining a custom leaf node that inherits io::PointDataGridMultiPass is no longer permitted.
