Classes

struct  NodeMaskOp
 Node Mask dilation/erosion operations for individual leaf nodes on a given tree. The leaf node may optionally belong to a different tree than the provided accessor, which will have the effect of dilating the leaf node mask into a different tree, or eroding the node mask based on corresponding neighbours in a different tree.

Member Function Documentation

void copyMasks ( std::vector< MaskType > &  masks) const
inline

Copy the current node masks onto the provided vector. The vector is resized if necessary.

Parameters
masksThe vector of NodeMasks to copy onto
void dilateVoxels ( const size_t  iter,
const NearestNeighbors  nn,
const bool  prune = false,
const bool  preserveMaskLeafNodes = false 
)

Topologically dilate all voxels by the provided nearest neighbour scheme and optionally collapse constant leaf nodes.

Voxel values are unchanged and only leaf nodes are used to propagate the dilation.

Parameters
iterNumber of dilation iterations
nnConnectivity pattern of the dilation
pruneWhether to collapse constant leaf nodes after the dilation
preserveMaskLeafNodesWhen dilating mask trees, the default behaviour chooses to steal the mask nodes rather than copy them. Although faster, this means that leaf nodes may be re-allocated. Set this to true if you need the original topology pointers to be preserved.
void erodeVoxels ( const size_t  iter,
const NearestNeighbors  nn,
const bool  prune = false 
)

Topologically erode all voxels by the provided nearest neighbour scheme and optionally collapse constant leaf nodes.

Inactive Tiles contribute to the erosion but active tiles are not modified.

Parameters
iterNumber of erosion iterations
nnConnectivity pattern of the erosion
pruneWhether to collapse constant leaf nodes after the erosion
bool getThreaded ( ) const
inline

Return whether this class is using multi-threading.

const tree::LeafManager<TreeType>& leafManager ( ) const
inline

Return a const reference to the leaf manager.

void setThreaded ( const bool  threaded)
inline

Set whether to use multi-threading.

Note
The grain size is not exposed
