catmull_rom_chain()

list path_generator.path_generator.catmull_rom_chain	(	np.ndarray	points,
		int	num_points
	)

Calculate Catmull-Rom for a sequence of initial points and return the combined curve.
:param points: Base points from which the quadruples for the algorithm are taken
:param num_points: The number of points to include in each curve segment
:return: The chain of all points (points of all segments)

catmull_rom_spline()

def path_generator.path_generator.catmull_rom_spline	(	tuple	P0,
		tuple	P1,
		tuple	P2,
		tuple	P3,
		int	num_points,
		float	alpha = 0.5
	)

Compute the points in the spline segment
:param P0, P1, P2, and P3: The (x,y) point pairs that define the Catmull-Rom spline
:param num_points: The number of points to include in the resulting curve segment
:param alpha: 0.5 for the centripetal spline, 0.0 for the uniform spline, 1.0 for the chordal spline.
:return: The points
