Constructor & Destructor Documentation

template<typename ChildT >

openvdb::OPENVDB_VERSION_NAME::tree::RootNode< ChildT >::RootNode ( )

inline

Construct a new tree with a background value of 0.

Definition at line 1072 of file RootNode.h.

template<typename ChildT >

openvdb::OPENVDB_VERSION_NAME::tree::RootNode< ChildT >::RootNode ( const ValueType & background )

inlineexplicit

Construct a new tree with the given background value.

Definition at line 1081 of file RootNode.h.

template<typename ChildType>

template<typename OtherChildType >

openvdb::OPENVDB_VERSION_NAME::tree::RootNode< ChildType >::RootNode ( const RootNode< OtherChildType > & other )

inlineexplicit

Construct a new tree that reproduces the topology and active states of a tree of a different ValueType but the same configuration (levels, node dimensions and branching factors). Cast the other tree's values to this tree's ValueType.

Exceptions

TypeError if the other tree's configuration doesn't match this tree's or if this tree's ValueType is not constructible from the other tree's ValueType.

Definition at line 85 of file RootNode.h.

template<typename ChildT >

template<typename OtherChildType >

openvdb::OPENVDB_VERSION_NAME::tree::RootNode< ChildT >::RootNode	(	const RootNode< OtherChildType > &	other,
		const ValueType &	background,
		const ValueType &	foreground,
		TopologyCopy
	)

inline

Construct a new tree that reproduces the topology and active states of another tree (which may have a different ValueType), but not the other tree's values.

All tiles and voxels that are active in the other tree are set to foreground in the new tree, and all inactive tiles and voxels are set to background.

Parameters

other	the root node of a tree having (possibly) a different ValueType
background	the value to which inactive tiles and voxels are initialized
foreground	the value to which active tiles and voxels are initialized

Exceptions

TypeError if the other tree's configuration doesn't match this tree's.

Definition at line 1091 of file RootNode.h.

template<typename ChildT >

template<typename OtherChildType >

openvdb::OPENVDB_VERSION_NAME::tree::RootNode< ChildT >::RootNode	(	const RootNode< OtherChildType > &	other,
		const ValueType &	background,
		TopologyCopy
	)

inline

Construct a new tree that reproduces the topology and active states of another tree (which may have a different ValueType), but not the other tree's values. All tiles and voxels in the new tree are set to background regardless of their active states in the other tree.

Parameters

other	the root node of a tree having (possibly) a different ValueType
background	the value to which inactive tiles and voxels are initialized

Note: This copy constructor is generally faster than the one that takes both a foreground and a background value. Its main application is in multithreaded operations where the topology of the output tree exactly matches the input tree.

Exceptions

TypeError if the other tree's configuration doesn't match this tree's.

RootNode& openvdb::OPENVDB_VERSION_NAME::tree::RootNode< ChildType >::operator= ( const RootNode< OtherChildType > & other )

Copy a root node of the same tree configuration as this node but a different ValueType.

Exceptions

TypeError if the other tree's configuration doesn't match this tree's.

Note: This node's ValueType must be constructible from the other node's ValueType. For example, a root node with values of type float can be assigned to a root node with values of type Vec3s, because a Vec3s can be constructed from a float. But a Vec3s root node cannot be assigned to a float root node.

inline

Difference this tree's set of active values with the active values of the other tree, whose ValueType may be different. So a resulting voxel will be active only if the original voxel is active in this tree and inactive in the other tree.

Note: This operation can delete branches in this grid if they overlap with active tiles in the other grid. Likewise active voxels can be turned into inactive voxels resulting in leaf nodes with no active values. Thus, it is recommended to subsequently call prune.

inline

Intersects this tree's set of active values with the active values of the other tree, whose ValueType may be different.

The resulting state of a value is active only if the corresponding value was already active AND if it is active in the other tree. Also, a resulting value maps to a voxel if the corresponding value already mapped to an active voxel in either of the two grids and it maps to an active tile or voxel in the other grid.

Note: This operation can delete branches in this grid if they overlap with inactive tiles in the other grid. Likewise active voxels can be turned into inactive voxels resulting in leaf nodes with no active values. Thus, it is recommended to subsequently call prune.

void openvdb::OPENVDB_VERSION_NAME::tree::RootNode< ChildT >::topologyUnion	(	const RootNode< OtherChildType > &	other,

	)

inline

Union this tree's set of active values with the active values of the other tree, whose ValueType may be different.

The resulting state of a value is active if the corresponding value was already active OR if it is active in the other tree. Also, a resulting value maps to a voxel if the corresponding value already mapped to a voxel OR if it is a voxel in the other tree. Thus, a resulting value can only map to a tile if the corresponding value already mapped to a tile AND if it is a tile value in other tree.

Note: This operation modifies only active states, not values. Specifically, active tiles and voxels in this tree are not changed, and tiles or voxels that were inactive in this tree but active in the other tree are marked as active in this tree but left with their original values.; If preserveTiles is true, any active tile in this topology will not be densified by overlapping child topology.
