Manim Slides

Tool for live presentations using either Manim (community edition) or ManimGL. Manim Slides will automatically detect the one you are using!

NOTE: this project extends the work of manim-presentation, with a lot more features!

Installation

While installing Manim Slides and its dependencies on your global Python is fine, I recommend using a virtual environment (e.g., venv) for a local installation.

Dependencies

Manim Slides requires either Manim or ManimGL to be installed. Having both packages installed is fine too.

If none of those packages are installed, please refer to their specific installation guidelines:

• Manim
• ManimGL

Pip Install

The recommended way to install the latest release is to use pip:

pip install manim-slides

Install From Repository

An alternative way to install Manim Slides is to clone the git repository, and install from there: read the contributing guide to know how.

Usage

Using Manim Slides is a two-step process:

1. Render animations using Slide (resp. ThreeDSlide) as a base class instead of Scene (resp. ThreeDScene), and add calls to self.pause() everytime you want to create a new slide.
2. Run manim-slides on rendered animations and display them like a Power Point presentation.

The documentation is available online.

Basic Example

Wrap a series of animations between self.start_loop() and self.stop_loop() when you want to loop them (until input to continue):

# example.py

from manim import *
# or: from manimlib import *
from manim_slides import Slide

class BasicExample(Slide):
    def construct(self):
        circle = Circle(radius=3, color=BLUE)
        dot = Dot()

        self.play(GrowFromCenter(circle))
        self.pause()  # Waits user to press continue to go to the next slide

        self.start_loop()  # Start loop
        self.play(MoveAlongPath(dot, circle), run_time=2, rate_func=linear)
        self.end_loop()  # This will loop until user inputs a key

        self.play(dot.animate.move_to(ORIGIN))
        self.pause()  # Waits user to press continue to go to the next slide

First, render the animation files:

manim example.py BasicExample
# or
manimgl example.py BasicExample

To start the presentation using Scene1, Scene2 and so on simply run:

manim-slides [OPTIONS] Scene1 Scene2...

Or in this example:

manim-slides BasicExample

Key Bindings

The default key bindings to control the presentation are:

You can run the configuration wizard to change those key bindings:

manim-slides wizard

A default file can be created with:

manim-slides init

NOTE: manim-slides uses key codes, which are platform dependent. Using the configuration wizard is therefore highly recommended.

Interactive Tutorial

Other Examples

Other examples are available in the example.py file, if you downloaded the git repository.

Below is a small recording of me playing with the slides back and forth.

F.A.Q

How to increase quality on Windows

On Windows platform, one may encounter a lower image resolution than expected. Usually, this is observed because Windows rescales every application to fit the screen. As found by @arashash, in #20, the problem can be addressed by changing the scaling factor to 100%:

in Settings->Display.
