Create a binary map of a sphere within a 3D grid
sphere = makeSphere(Nx, Ny, Nz, radius)
makeSphere
creates a binary map of a spherical shell (using an extension of the midpoint circle algorithm) within a three-dimensional grid (the sphere position is denoted by 1's in the matrix with 0's elsewhere). A visualisation of the 3D grid returned by calling makeSphere(64, 64, 64, 20)
and a cut away showing the singel pixel width (for illustrative purposes only) are given below.
