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)

◆ ConstPtrCast()

SharedPtr<T> openvdb::v6_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::Ptr nonConstGrid = ConstPtrCast<FloatGrid>(grid);
FloatGrid::ConstPtr constGrid = ConstPtrCast<const FloatGrid>(nonConstGrid);

◆ createGrid() [1/3]

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).

◆ createGrid() [2/3]

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().

◆ createGrid() [3/3]

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).

◆ createLevelSet()

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
voxelSizethe size of a voxel in world units
halfWidththe 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.

◆ deepCopyTypedGrid() [1/2]

GridType::Ptr openvdb::v6_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.

◆ deepCopyTypedGrid() [2/2]

GridType::Ptr openvdb::v6_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.

◆ DynamicPtrCast()

SharedPtr<T> openvdb::v6_0::DynamicPtrCast ( const SharedPtr< U > &  ptr)

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

GridPtrContainerT::value_type openvdb::v6_0::findGridByName ( const GridPtrContainerT &  container,
const Name name 
)

GridType::ConstPtr openvdb::v6_0::gridConstPtrCast ( const GridBase::ConstPtr grid)
inline

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

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

◆ gridPtrCast()

GridType::Ptr openvdb::v6_0::gridPtrCast ( const GridBase::Ptr grid)
inline
