manim-express 0.2

Animation engine for explanatory math videos

Install

pip install manim_express

The above steps will automatically install packages manim_express and manimlib(my fork version) for you. Then you can code with them anywhere.

Quick start

• Render an animation: SquareToCircle

  from manimlib import *
  from manim_express import EagerModeScene
  
  scene = EagerModeScene()
  circle = Circle()
  circle.set_fill(BLUE, opacity=0.5)
  circle.set_stroke(BLUE_E, width=4)
  
  square = Square()
  scene.play(ShowCreation(square))
  scene.play(ReplacementTransform(square, circle))
  
  scene.hold_on()
  

• manim_express vs Matplotlib:

  from manimlib import *
  from manim_express import EagerModeScene
  import numpy as np
  
  x = np.linspace(0, 2*np.pi, 100)
  y = np.sin(5*x)
  
  # matplotlib
  import matplotlib.pyplot as plt
  
  plt.plot(x, y, color='green', linewidth=2)
  plt.show()
  
  # manim_express
  scene = EagerModeScene()
  
  scene.plot(x, y, color=GREEN, width=2)
  scene.show_plot()
  
  scene.hold_on()
