Classes
struct	SameLeafConfig< Dim1, NodeT2 >
class	PointDataLeafNode< T, Log2Dim >
class	PointDataLeafNode< T, Log2Dim >
struct	PointDataNodeChain< HeadT, HeadLevel >
	Recursive node chain which generates a openvdb::TypeList value converted types of nodes to PointDataGrid nodes of the same configuration, rooted at RootNodeType in reverse order, from LeafNode to RootNode. See also TreeConverter<>. More...
struct	PointDataNodeChain< tree::InternalNode< ChildT, Log2Dim >, HeadLevel >
struct	PointDataNodeChain< tree::InternalNode< ChildT, Log2Dim >, 1 >
struct	TreeConverter< TreeType >
	Similiar to ValueConverter, but allows for tree configuration conversion to a PointDataTree. ValueConverter<PointDataIndex32> cannot be used as a PointDataLeafNode is not a specialization of LeafNode. More...

Typedefs
using	PointDataTree = tree::Tree< tree::RootNode< tree::InternalNode< tree::InternalNode< PointDataLeafNode< PointDataIndex32, 3 >, 4 >, 5 >>>
	Point index tree configured to match the default VDB configurations. More...
using	PointDataGrid = Grid< PointDataTree >
	Point data grid. More...

Functions
template<>
void	readCompressedValues (std::istream &is, PointDataIndex32 *destBuf, Index destCount, const util::NodeMask< 3 > &, bool)
	openvdb::io::readCompressedValues specialized on PointDataIndex32 arrays to ignore the value mask, use a larger block size and use 16-bit size instead of 64-bit More...
template<>
void	writeCompressedValues (std::ostream &os, PointDataIndex32 *srcBuf, Index srcCount, const util::NodeMask< 3 > &, const util::NodeMask< 3 > &, bool)
	openvdb::io::writeCompressedValues specialized on PointDataIndex32 arrays to ignore the value mask, use a larger block size and use 16-bit size instead of 64-bit More...
template<typename T >
void	writeCompressedValuesSize (std::ostream &os, const T *srcBuf, Index srcCount)
template<typename PointDataTreeT >
AttributeSet::Descriptor::Ptr	makeDescriptorUnique (PointDataTreeT &tree)
	Deep copy the descriptor across all leaf nodes. More...
template<typename PointDataTreeT >
void	setStreamingMode (PointDataTreeT &tree, bool on=true)
	Toggle the streaming mode on all attributes in the tree to collapse the attributes after deconstructing a bound AttributeHandle to each array. This results in better memory efficiency when the data is streamed into another data structure (typically for rendering). More...
template<typename PointDataTreeT >
void	prefetch (PointDataTreeT &tree, bool position=true, bool otherAttributes=true)
	Sequentially pre-fetch all delayed-load voxel and attribute data from disk in order to accelerate subsequent random access. More...
void	initialize ()
	Global registration of point data-related types. More...
void	uninitialize ()
	Global deregistration of point data-related types. More...
