Detailed Description

template<typename TreeType>
class openvdb::v0_104_0::tree::ValueAccessor0< TreeType >

ValueAccessor with no mutex and no node caching.

Note
This specialization is mostly useful for benchmark comparisons, since the cached versions are always expected to be faster.

Member Function Documentation

virtual void clear ( )
inlinevirtual

Remove all nodes from this cache, then reinsert the root node.

Implements ValueAccessorBase< _TreeType >.

void eraseNode ( )
inline

If a node of the given type exists in the cache, remove it, so that isCached(xyz) returns false for any voxel (x, y, z) contained in that node. [Mainly for internal use]

NodeT* getNode ( )
inline

Return the cached node of type NodeType. [Mainly for internal use].

_TreeType * getTree ( ) const
inlineinherited
Returns
a pointer to the tree associated by this ValueAccessor
const ValueType& getValue ( const Coord xyz) const
inline

Return the value of the voxel at the given coordinates.

int getValueDepth ( const Coord xyz) const
inline

Return the tree depth (0 = root) at which the value of voxel (x, y, z) resides, or -1 if (x, y, z) isn't explicitly represented in the tree (i.e., if it is implicitly a background voxel).

void insertNode ( const Coord ,
NodeT &   
)
inline

Cache the given node, which should lie along the path from the root node to the node containing voxel (x, y, z). [Mainly for internal use]

bool isCached ( const Coord ) const
inline

Return true if nodes along the path to the given voxel have been cached.

bool isValueOn ( const Coord xyz) const
inline

Return the active state of the voxel at the given coordinates.

bool isVoxel ( const Coord xyz) const
inline

Return true if the value of voxel (x, y, z) resides at the leaf level of the tree, i.e., if it is not a tile value.

static Index numCacheLevels ( )
inlinestatic

Return the number of cache levels employed by this ValueAccessor.

const LeafNodeT* probeConstLeaf ( const Coord xyz)
inline
LeafNodeT* probeLeaf ( const Coord xyz)
inline
bool probeValue ( const Coord xyz,
ValueType value 
) const
inline

Return the active state of the voxel as well as its value.

void setActiveState ( const Coord xyz,
bool  on = true 
)
inline

Set the active state of the voxel at the given coordinates without changing its value.

void setValue ( const Coord xyz,
const ValueType value 
)
inline

Set the value of the voxel at the given coordinates and mark the voxel as active.

void setValueOff ( const Coord xyz,
const ValueType value 
)
inline

Set the value of the voxel at the given coordinates and mark the voxel as inactive.

void setValueOff ( const Coord xyz)
inline

Mark the voxel at the given coordinates as inactive without changing its value.

void setValueOn ( const Coord xyz,
const ValueType value 
)
inline

Set the value of the voxel at the given coordinates and mark the voxel as active.

void setValueOn ( const Coord xyz)
inline

Mark the voxel at the given coordinates as active without changing its value.

void setValueOnly ( const Coord xyz,
const ValueType value 
)
inline

Set the value of the voxel at the given coordinate but preserves its active state.

void setValueOnSum ( const Coord xyz,
const ValueType value 
)
inline

Set the value of the voxel at the given coordinates to the sum of its current value and the given value, and mark the voxel as active.
