サンプルコード

from manim import *

class test(ThreeDScene):
	def construct(self):
		axes_3d = ThreeDAxes(x_range = (-6, 6, 1), x_length = 12, y_range = (-5, 5, 1), y_length = 10, z_range = (-3, 3, 1), z_length = 6,)
		self.set_camera_orientation(phi = 70 * DEGREES, theta = 240 * DEGREES)
		surface = Surface(lambda u, v: np.array([np.cos(TAU * v), np.sin(TAU * v), 2 * (1 - u)]),).fade(0.5)
		paraboloid = Surface(lambda u, v: np.array([np.cos(v) * u, np.sin(v) * u, u ** 2]), v_range = (0, TAU),).fade(0.5)
		para_hyp = Surface(lambda u, v: np.array([u, v, u ** 2 - v ** 2]), u_range = (-2, 2), v_range = (-2, 2),).fade(0.5)
		cone = Surface(lambda u, v: np.array([u * np.cos(v), u * np.sin(v), u]), u_range = (-2, 2), v_range = (0, TAU),)

		self.add(axes_3d, surface)
		self.play(Transform(surface, paraboloid))
