Manim's method 8

Overview

I checked manim's method. I tried using NumberPlane and ParametricFunction.

Sample code

from manimlib.imports import *

def lissajous_curve_func(t):
	return np.array((np.sin(2 * t) * 3, np.sin(3 * t) * 3, 0))

class test(Scene):
	def construct(self):
		grid = NumberPlane()
		self.add(grid)
		func = ParametricFunction(lissajous_curve_func, t_max = TAU, fill_opacity = 0)
		#dot = Dot()
		#self.add(dot)
		self.add(func)
		self.wait()

result

that's all.
