Returns ------- splines: List a list of spline functions. each list item is a different N-dimensional spline which can be evaluated along the interval [0,1]. Vessel data evaluations are given in xyzr format. This means the x-coordinate, y-coordinate, z-coordinate, and radius value are returned in this order. Example: >>> splines = load_splines() >>> splines[0](0) # we are evaluating the first spline at zero [array(0.02465846), array(-1.3615156), array(1.86000645), array(0.06768623)] >>> >>> x,y,z,r = splines[0](0) # we can store the data into the relevant variables >>> print(x) array(0.02465846) >>>print(y) array(-1.3615156) >>>print(z) array(1.86000645) >>>print(r) array(0.06768623) """ filename = askopenfilename() file = open(filename,'rb') splines = pickle.load(file) return splines
