Requirements

manim_kunyuan >= 0.23
sparrow_tool
fake_headers

# helium
# pyperclip

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: 3b1b: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()
    

    Operating graphics:

    • hold down the d key on the keyboard and move the mouse to change the three-dimensional perspective.
    • hold down the s key on the keyboard and move the mouse to pan the screen
    • hold down the z on the keyboard while scrolling the middle mouse button to zoom the screen
    • scroll the middle mouse button to move the screen up and down
    • reset camera view by pressing r
    • close the window and exit the program by pressing q
  • manim_express vs Matplotlib:
    In some cases, you may need to install LaTeX to render tex fonts.
    Fortunately, online latex compilation option is available. Just set SceneArgs.use_online_tex=True

    from manimlib import *
    from manim_express import *
    import numpy as np
    SceneArgs.use_online_tex = True # Use online latex compiler
    
    theta = np.linspace(0, 2*np.pi, 200)
    x = np.cos(theta)
    y = np.sin(theta)
    
    # matplotlib
    # import matplotlib.pyplot as plt
    # plt.plot(x, y, color='green', linewidth=2)
    # plt.axis("equal")
    # plt.show()
    
    # manim_express
    scene = EagerModeScene()
    scene.plot(x, y, color=GREEN, width=2, scale_ratio=1)
    scene.show_plot()
    
    scene.hold_on()
