inline

const DataType* data ( ) const

inline

static uint32_t dim ( )

inlinestatic

Return the dimension, in index space, of this leaf node (typically 8 as for openvdb leaf nodes!)

uint8_t flags ( ) const

inline

ValueType getValue ( uint32_t offset ) const

inline

Return the voxel value at the given offset.

ValueType getValue ( const CoordT & ijk ) const

inline

Return the voxel value at the given coordinate.

bool isActive ( const CoordT & ijk ) const

inline

Return true if the voxel value at the given coordinate is active.

bool isActive ( uint32_t n ) const

inline

bool isActive ( ) const

inline

Return true if any of the voxel value are active in this leaf node.

void localToGlobalCoord ( Coord & ijk ) const

inline

Converts (in place) a local index coordinate to a global index coordinate.

ValueType maximum ( ) const

inline

Return a const reference to the maximum active value encoded in this leaf node.

static uint64_t memUsage ( )

inlinestatic

return memory usage in bytes for the class

ValueType minimum ( ) const

inline

Return a const reference to the minimum active value encoded in this leaf node.

CoordT offsetToGlobalCoord ( uint32_t n ) const

inline

static CoordT OffsetToLocalCoord ( uint32_t n )

inlinestatic

LeafNode& operator= ( const LeafNode< BuildT, CoordT, MaskT, Log2Dim > & )

delete

CoordT origin ( ) const

inline

Return the origin in index space of this leaf node.

const LeafNode* probeLeaf ( const CoordT & ) const

inline

bool probeValue	(	const CoordT &	ijk,
		ValueType &	v
	)		const

inline

Return true if the voxel value at the given coordinate is active and updates v with the value.

void setValue	(	const CoordT &	ijk,
		const ValueType &	v
	)

inline

Sets the value at the specified location and activate its state.

Note: This is safe since it does not change the topology of the tree (unlike setValue methods on the other nodes)

void setValueOnly	(	uint32_t	offset,
		const ValueType &	v
	)

inline

Sets the value at the specified location but leaves its state unchanged.

Note: This is safe since it does not change the topology of the tree (unlike setValue methods on the other nodes)

void setValueOnly	(	const CoordT &	ijk,
		const ValueType &	v
	)

inline

FloatType stdDeviation ( ) const

inline

Return a const reference to the standard deviation of all the active values encoded in this leaf node.

void updateBBox ( )

inline

Updates the local bounding box of active voxels in this node.

Warning: It assumes that the origin and value mask have already been set.

This method is based on few (intrinsic) bit operations and hence is relatively fast. However, it should only only be called of either the value mask has changed or if the active bounding box is still undefined. e.g. during constrution of this node.

const MaskType<LOG2DIM>& valueMask ( ) const

inline

Return a const reference to the bit mask of active voxels in this leaf node.

FloatType variance ( ) const

inline

Return the variance of all the active values encoded in this leaf node.

static uint32_t voxelCount ( )

inlinestatic

Return the total number of voxels (e.g. values) encoded in this leaf node.
