Manim's method 20

Overview

I checked manim's method. I tried using MovingCameraScene.

Sample code

from manimlib.imports import *

class test(GraphScene, MovingCameraScene):
	def setup(self):
		GraphScene.setup(self)
		MovingCameraScene.setup(self)
	def construct(self):
		self.camera_frame.save_state()
		self.setup_axes(animate = False)
		graph = self.get_graph(lambda x: np.sin(x), color = BLUE, x_min = 0, x_max = 3 * PI)
		moving_dot = Dot().move_to(graph.points[0]).set_color(ORANGE)
		dot_at_start_graph = Dot().move_to(graph.points[0])
		dot_at_end_grap = Dot().move_to(graph.points[-1])
		self.add(graph, dot_at_end_grap, dot_at_start_graph, moving_dot)
		self.play(self.camera_frame.scale, 0.5, self.camera_frame.move_to, moving_dot)
		def update_curve(mob):
			mob.move_to(moving_dot.get_center())
		self.camera_frame.add_updater(update_curve)
		self.play(MoveAlongPath(moving_dot, graph, rate_func = linear))
		self.camera_frame.remove_updater(update_curve)
		self.play(Restore(self.camera_frame))
