Internal function that projects a hemisphere or spherical dome through the image stack to determine the end voxels of each possible path from a seed point.
hemisphere.points(radius, show.plot = FALSE, backstep = 0)Returns a matrix with 3D coordinates of the end points of the possible paths
The number of images out from the seed point plane to sample
Generates a 3D plot showing the end points of possible paths
Should images in the seed point plane or behind it be considered. Each value (1, 2, 3, etc.) gives the number of images "behind" the seed point to consider in the spherical dome
