butterfly

Identify butterflies from a <code>VoxelSpace</code> object.
A butterfly refers to a non-empty isolated voxel. Non-empty means that there
is one or more hits recorded in the voxel. Isolated means that voxels in the
<a href="https://en.wikipedia.org/wiki/Moore_neighborhood">Moore neighborhood</a>
of rank 1 are empty (no hit).

Read, manipulate and write voxel spaces. Voxel spaces are
read from text-based output files of the 'AMAPVox' software. 'AMAPVox'
is a LiDAR point cloud voxelisation software that aims at estimating
leaf area through several theoretical/numerical approaches. See more
in the article Vincent et al. (2017) <doi:10.23708/1AJNMP> and the
technical note Vincent et al. (2021) <doi:10.23708/1AJNMP>.
