Manim Slides

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!
