description Tool for live presentations using manim.

Manim Slides is an extension to Manim that allows to create nice presentations from already existing Manim animations1, with minimal changes required.

From an already existing code:

from manim import *

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

        self.play(GrowFromCenter(circle))

        self.play(MoveAlongPath(dot, circle), run_time=2, rate_func=linear)

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

You can very simply turn it into a slideshow:

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

The rendered output can be seen on this page.

Story

During May ~ June 2022, I discovered manim-presentation, a tool that allows to present Manim animations in a PowerPoint-like manner. Very rapidly, I decided to use this tool to create my presentation for the COST Interact 2022 meeting (see blog post). In March 2023, I presented my work at EuCAP2023, for which the slides are available here.

This first experience was great, but I felt like some important features were missing, like support for ManimGL. As the main GitHub repository was relatively inactive, in September 2022, I decided to fork it and work on my own project.

Since, the initial codebase has completely changed, and this project has evolved a lot. If you are interested, I highly recommend you to check it out!
