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 neighbors in a different tree.

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

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 neighbor scheme and optionally collapse constant leaf nodes.
Voxel values are unchanged and only leaf nodes are used to propagate the dilation.
iter | Number of dilation iterations |
nn | Connectivity pattern of the dilation |
prune | Whether to collapse constant leaf nodes after the dilation |
preserveMaskLeafNodes | When 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 neighbor scheme and optionally collapse constant leaf nodes.
Inactive Tiles contribute to the erosion but active tiles are not modified.
iter | Number of erosion iterations |
nn | Connectivity pattern of the erosion |
prune | Whether to collapse constant leaf nodes after the erosion |
