Illustration of the first search. The selection is carried out in a four-dimensional space with the first three dimensions being the local Rodrigues space (voxelized) and the fourth dimension a mask of the geodesic labels passing through the voxels. Shown is the Boolean OR operation between a bit indicating the number of the geodesic (A) and the fourth dimension for a given voxel (B), leading to an update of this fourth dimension, representing the geodesics that have been found to pass the voxel so far (C). |
