Specify how grids should be merged during certain (typically multithreaded) operations.

MERGE_ACTIVE_STATES

  The output grid is active wherever any of the input grids is active.

MERGE_NODES

  The output grid's tree has a node wherever any of the input grids' trees has a node, regardless of any active states.

MERGE_ACTIVE_STATES_AND_NODES
  The output grid is active wherever any of the input grids is active, and its tree has a node wherever any of the input grids' trees has a node.

## ◆ VecType

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

## ◆ ConstPtrCast()

SharedPtr<T> openvdb::v7_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);

## ◆ createGrid() [1/3]

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() [2/3]

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() [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

  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.

## ◆ deepCopyTypedGrid() [1/2]

GridType::Ptr openvdb::v7_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`.

## ◆ deepCopyTypedGrid() [2/2]

GridType::Ptr openvdb::v7_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`.

## ◆ DynamicPtrCast()

SharedPtr<T> openvdb::v7_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);

## ◆ findGridByName() [1/2]

GridPtrContainerT::value_type openvdb::v7_0::findGridByName | ( | const GridPtrContainerT & | container,

| inline

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

## ◆ findGridByName() [2/2]

|  | const Name & | name
| ) |  |
| inline

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

## ◆ getLibraryVersionString()

constexpr const char* openvdb::v7_0::getLibraryVersionString | ( |  | ) |

GridType::ConstPtr openvdb::v7_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).

## ◆ gridPtrCast()

GridType::Ptr openvdb::v7_0::gridPtrCast | ( | const GridBase::Ptr & | grid | ) |
| inline
