Figure 1

CDA1 and CDA2 for generating a 3D curve using one computer-mouse stroke painted in the 2D projection of a 3D image of a dragonfly thoracic ganglion neuron. R1~RN: the first to the last shooting rays, which are parallel to each other and along the path of the mouse stroke. p1~pN: the estimated 3D location of each curve knot, each corresponding to a shooting ray. qk,i and q(k+1),i: the one-voxel evenly spaced 3D locations along the kth and (k+1)th rays, respectively; the final knot location pk for the ray Rk is selected from the set.
