struct	index_sequence
	Re-implementation of C++17's index_sequence and the helper alias make_index_sequence.

enum VecType

The type of a vector determines how transforms are applied to it:

Invariant

Does not transform (e.g., tuple, uvw, color)

Covariant

Apply inverse-transpose transformation: w = 0, ignores translation (e.g., gradient/normal)

Covariant Normalize

Apply inverse-transpose transformation: w = 0, ignores translation, vectors are renormalized (e.g., unit normal)

Contravariant Relative

Apply "regular" transformation: w = 0, ignores translation (e.g., displacement, velocity, acceleration)

Contravariant Absolute

Apply "regular" transformation: w = 1, vector translates (e.g., position)

Function Documentation

void openvdb::v12_0::assertAbort	(	const char *	assertion,
		const char *	file,
		const unsigned	line,
		const char *	function,
		const char *	msg = `nullptr`
	)

Trigger a SIGABRT after printing a formatted assertion message. Effectively performs the same functionality as cassert, but allows VDB code to call this independently of the NDEBUG define.

Parameters

assertion	The variable or expression that triggered the assertion as a string
file	The name of the file the assertion occurred
line	The line in the file the assertion occurred
function	The name of the function the assertion occurred in
msg	An optional descriptive message

SharedPtr<T> openvdb::v12_0::ConstPtrCast ( const SharedPtr< U > & ptr )

inline

Return a new shared pointer that points to the same object as the given pointer but with possibly different const-ness.

Example:: FloatGrid::ConstPtr grid = ...;
FloatGrid::Ptr nonConstGrid = ConstPtrCast<FloatGrid>(grid);
FloatGrid::ConstPtr constGrid = ConstPtrCast<const FloatGrid>(nonConstGrid);

GridType::Ptr createGrid ( const typename GridType::ValueType & background )

inline

Create a new grid of type GridType with a given background value.

Note: Calling createGrid<GridType>(background) is equivalent to calling GridType::create(background).

GridType::Ptr createGrid ( )

inline

Create a new grid of type GridType with background value zero.

Note: Calling createGrid<GridType>() is equivalent to calling GridType::create().

Grid< typename TreePtrType::element_type >::Ptr createGrid ( TreePtrType tree )

inline

Create a new grid of the appropriate type that wraps the given tree.

Note: This function can be called without specifying the template argument, i.e., as createGrid(tree).

GridType::Ptr createLevelSet	(	Real	voxelSize = `1.0`,
		Real	halfWidth = `LEVEL_SET_HALF_WIDTH`
	)

Create a new grid of type GridType classified as a "Level Set", i.e., a narrow-band level set.

Note: GridType::ValueType must be a floating-point scalar.

Parameters

voxelSize	the size of a voxel in world units
halfWidth	the half width of the narrow band in voxel units

The voxel size and the narrow band half width define the grid's background value as halfWidth*voxelWidth. The transform is linear with a uniform scaling only corresponding to the specified voxel size.

Note: It is generally advisable to specify a half-width of the narrow band that is larger than one voxel unit, otherwise zero crossings are not guaranteed.

GridType::Ptr openvdb::v12_0::deepCopyTypedGrid ( const GridBase::ConstPtr & grid )

inline

Return a pointer to a deep copy of the given grid, provided that the grid's concrete type is GridType.

Return a null pointer if the input pointer is null or if it points to a grid that is not of type GridType.

GridType::Ptr openvdb::v12_0::deepCopyTypedGrid ( const GridBase & grid )

inline

Return a pointer to a deep copy of the given grid, provided that the grid's concrete type is GridType.

Return a null pointer if the input pointer is null or if it points to a grid that is not of type GridType.

SharedPtr<T> openvdb::v12_0::DynamicPtrCast ( const SharedPtr< U > & ptr )

inline

Return a new shared pointer that is either null or points to the same object as the given pointer after a dynamic_cast.

Example:: GridBase::ConstPtr grid = ...;
FloatGrid::ConstPtr floatGrid = DynamicPtrCast<const FloatGrid>(grid);

OPENVDB_FORCE_INLINE RetT openvdb::v12_0::evalFirstIndex	(	OpT	op,
		const RetT	def = `RetT()`
	)

GridPtrContainerT::value_type openvdb::v12_0::findGridByName	(	const GridPtrContainerT &	container,
		const Name &	name
	)

inline

Return the first grid in the given container whose name is name.

GridPtrT openvdb::v12_0::findGridByName	(	const std::map< KeyT, GridPtrT > &	container,
		const Name &	name
	)

inline

Return the first grid in the given map whose name is name.

GridType::ConstPtr openvdb::v12_0::gridConstPtrCast ( const GridBase::ConstPtr & grid )

inline

Cast a generic const grid pointer to a const pointer to a grid of a concrete class.

Return a null pointer if the input pointer is null or if it points to a grid that is not of type GridType.

Note: Calling gridConstPtrCast<GridType>(grid) is equivalent to calling GridBase::constGrid<GridType>(grid).

GridType::Ptr openvdb::v12_0::gridPtrCast ( const GridBase::Ptr & grid )

inline

Cast a generic grid pointer to a pointer to a grid of a concrete class.

Return a null pointer if the input pointer is null or if it points to a grid that is not of type GridType.

Note: Calling gridPtrCast<GridType>(grid) is equivalent to calling GridBase::grid<GridType>(grid).

OPENVDB_IMPORT void openvdb::v12_0::initialize ( )

Global registration of native Grid, Transform, Metadata and Point attribute types. Also initializes blosc (if enabled).

Calling this methods registers factory callbacks for the set of native grid, transform, metadata and point attribute types that OpenVDB supports by default. For most types, calling openvdb::initialize is only required for serialization support. However, openvdb::initialize must be called for PointDataGrid attribute usage as these callbacks are used in various tools.

Note: This method is thread safe - it can be concurrently called multiple times, early exiting if it has already been called so long as openvdb::uninitialize() has not been called.

auto openvdb::v12_0::make_index_sequence_impl ( )

std::ostream& openvdb::v12_0::operator<<	(	std::ostream &	,
		const MetaMap &
