Detailed Description

template<typename ValueT, MemoryLayout Layout = LayoutZYX>
class openvdb::v9_0::tools::Dense< ValueT, Layout >

Dense is a simple dense grid API used by the CopyToDense and CopyFromDense classes defined below.

Use the Dense class to efficiently produce a dense in-memory representation of an OpenVDB grid. However, be aware that a dense grid could have a memory footprint that is orders of magnitude larger than the sparse grid from which it originates.

Note: This class can be used as a simple wrapper for existing dense grid classes if they provide access to the raw data array.; This implementation allows for the 3D memory layout to be defined by the MemoryLayout template parameter (see above for definition). The default memory layout is ZYX since that's the layout used by OpenVDB grids.

Constructor & Destructor Documentation

Dense ( const CoordBBox & bbox )

inline

Construct a dense grid with a given range of coordinates.

Parameters

bbox	the bounding box of the (signed) coordinate range of this grid

Exceptions

ValueError if the bounding box is empty.

Note: The min and max coordinates of the bounding box are inclusive.

Dense	(	const CoordBBox &	bbox,
		const ValueT &	value
	)

inline

Construct a dense grid with a given range of coordinates and initial value.

Parameters

bbox	the bounding box of the (signed) coordinate range of this grid
value	the initial value of the grid.

Exceptions

ValueError if the bounding box is empty.

Note: The min and max coordinates of the bounding box are inclusive.

Dense	(	const CoordBBox &	bbox,
		ValueT *	data
	)

inline

Construct a dense grid that wraps an external array.

Parameters

bbox	the bounding box of the (signed) coordinate range of this grid
data	a raw C-style array whose size is commensurate with the coordinate domain of bbox

Note: The data array is assumed to have a stride of one in the z direction.

Exceptions

ValueError if the bounding box is empty.

Note: The min and max coordinates of the bounding box are inclusive.

Dense	(	const Coord &	dim,
		const Coord &	min = `Coord(0)`
	)

inline

Construct a dense grid with a given origin and dimensions.

Parameters

dim	the desired dimensions of the grid
min	the signed coordinates of the first voxel in the dense grid

Exceptions

ValueError if any of the dimensions are zero.

Note: The min coordinate is inclusive, and the max coordinate will be min + dim - 1.

Member Function Documentation

const CoordBBox& bbox ( ) const

inline

Return the bounding box of the signed index domain of this grid.

Note: This method is required by both CopyToDense and CopyFromDense.

size_t coordToOffset ( const Coord & xyz ) const

inline

Return the linear offset into this grid's value array given by the specified signed coordinates, i.e., coordinates in the space of this grid's bounding box.

Note: This method reflects the fact that we assume the same layout of values as an OpenVDB grid, i.e., the fastest coordinate is z.

ValueT* data ( )

inline

Return a raw pointer to this grid's value array.

Note: This method is required by CopyToDense.

const ValueT* data ( ) const

inline

Return a raw pointer to this grid's value array.

Note: This method is required by CopyFromDense.

void fill ( const ValueT & value )

inline

Fill this grid with a constant value.

const ValueT& getValue ( size_t offset ) const

inline

Return a const reference to the value of the voxel at the given array offset.

ValueT& getValue ( size_t offset )

inline

Return a non-const reference to the value of the voxel at the given array offset.

const ValueT& getValue	(	size_t	i,
		size_t	j,
		size_t	k
	)		const

inline

Return a const reference to the value of the voxel at unsigned index coordinates (i, j, k).

Note: This is somewhat slower than using an array offset.

ValueT& getValue	(	size_t	i,
		size_t	j,
		size_t	k
	)

inline

Return a non-const reference to the value of the voxel at unsigned index coordinates (i, j, k).

Note: This is somewhat slower than using an array offset.

const ValueT& getValue ( const Coord & xyz ) const

inline

Return a const reference to the value of the voxel at the given signed coordinates.

Note: This is slower than using either an array offset or unsigned index coordinates.

ValueT& getValue ( const Coord & xyz )

inline

Return a non-const reference to the value of the voxel at the given signed coordinates.

Note: This is slower than using either an array offset or unsigned index coordinates.

static MemoryLayout memoryLayout ( )

Index64 memUsage ( ) const

inline

Return the memory footprint of this Dense grid in bytes.

Coord offsetToCoord ( size_t n ) const

inline

Return the global coordinate corresponding to the specified linear offset.

const Coord& origin ( ) const

inline

void print	(	const std::string &	name = `""`,
		std::ostream &	os = `std::cout`
	)		const

inline

Output a human-readable description of this grid to the specified stream.

void setValue	(	size_t	offset,
		const ValueT &	value
	)

inline

Set the value of the voxel at the given array offset.

void setValue	(	size_t	i,
		size_t	j,
		size_t	k,
		const ValueT &	value
	)

inline

Set the value of the voxel at unsigned index coordinates (i, j, k).

Note: This is somewhat slower than using an array offset.

void setValue	(	const Coord &	xyz,
		const ValueT &	value
	)

inline

Set the value of the voxel at the given signed coordinates.

Note: This is slower than using either an array offset or unsigned index coordinates.

Index64 valueCount ( ) const

inline

Return the number of voxels contained in this grid.
