Installation

Manim Slides requires either Manim or ManimGL to be installed, along with their dependencies. Please checkout the documentation for detailed install instructions.

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.next_slide() everytime you want to create a new slide.
2. Run manim-slides on rendered animations and display them like a PowerPoint presentation.

The documentation is available online.

Basic Example

Call self.next_slide() everytime you want to create a pause between animations, and self.next_slide(loop=True) if you want the next slide to loop over animations until the user presses continue:

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.next_slide()  # Waits user to press continue to go to the next slide

        self.next_slide(loop=True)  # Start loop
        self.play(MoveAlongPath(dot, circle), run_time=2, rate_func=linear)
        self.next_slide()  # This will start a new non-looping slide

        self.play(dot.animate.move_to(ORIGIN))

First, render the animation files:

manim-slides render example.py BasicExample
# or use ManimGL
manim-slides render --GL example.py BasicExample

Note

Using manim-slides render makes sure the use the manim (or manimlib) library that was installed in the Python same environment. Put simply, this is a wrapper of manim render [ARGS]... (or manimgl [ARGS]...).

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

manim-slides [OPTIONS] Scene1 Scene2...

In our example:

manim-slides BasicExample

For detailed usage documentation, run manim-slides --help, or go to the documentation.

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.
