# Install

```bash
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](https://3b1b.github.io/manim/getting_started/quickstart.html#add-animations)

  ```python
  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](https://www.latex-project.org/get/#tex-distributions) to render `tex` fonts.  
  Fortunately, online latex compilation option is available. Just set `SceneArgs.use_online_tex=True`

  ```python
  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()
  ```
