    ff=list()
    ff$x=c(-4.850,-4.700,-3.934,-2.528, 0.603, 2.647, 3.861, 2.626)
    ff$y=c(-4.045,-2.087,-0.710, 0.172, 1.291, 2.087,-0.753,-4.131)

    G =getsplineG(ff$x, ff$y, kdiv=20)
    g = PointsAlong(G$x, G$y, N=5)

    plot(c(-5,5), c(-5,5), asp=1, type='n' )
    lines(G)

    faultperp(G$x, G$y, N = 10, endtol = 0.1, h = .3, col = "black")
