Source code for YouTube videos at Totient

Manim is an animation engine for explanatory math videos. It's used to create precise animations programmatically, as seen in the videos at 3Blue1Brown.

NOTE: This repository is maintained by the Manim Community, and is not associated with Grant Sanderson or 3Blue1Brown in any way (though we are definitely indebted to him for providing his work to the world). If you want to study how Grant makes his videos, head over to the main repository (3b1b/manim). This is a more frequently updated repository than the main one, and is recommended if you want to use Manim for your own projects.

Installation

Windows

Before installing manim-community, there are some additional dependencies that you must have installed:

• Cairo
• FFmpeg
• Sox (optional, for sound)
• LaTeX (optional, for LaTeX)

Cairo Installation

1. Visit the Download Page
2. Select the download that corresponds to your PC's architechture and Python Version

cp38 corresponds to Python 3.8, cp37 corresponds to Python 3.7, etc win_amd64 corresponds to 64-bit machines, win32 corresponds to 32-bit machines

3. Open up your command prompt by hitting the Win key and typing cmd

4. Enter the directory where you install cairo by typing cd C:\path\to\cairo with the path being where you downloaded the .whl file

5. Finally, run pip3 install (cairo-file).whl, where the file the appropriate name of the .whl file.

6. Alternatively, Running the command below installs pycairo. This needs to be an elevated command prompt like Powershell.

SoX Installation

1. Go to the SoX SourceForge page
2. Select the newest version, and download the .exe file

3. Add SoX to your PATH
   • Find the directory where SoX is installed. By default, this is probably C:\Program Files (x86)\sox-(version_number) or C:\Program Files\sox-(version_number)
   • Open a command prompt window by hitting the Win key and typing cmd
   • Run this command to update your PATH: setx PATH %PATH%;C:\Program Files (x86)\sox-(version_number)
   • Check you did it right by running refreshenv to update your environment variable and running sox

LaTeX Installation

1. Download the MiKTex installer from its Download Page
2. You can check you did it right by running refreshenv to update your environment variable and running latex

Ubuntu/Debian

Before installing manim-community, there are some additional dependencies that you must have installed:

• Cairo
• FFmpeg
• Sox (optional, for sound)
• LaTeX (optional, for LaTeX)

Cairo Installation

1. Install the libcairo2-dev package with your package manager: sudo apt-get install libcairo2-dev

FFmpeg Installation

1. Install the ffmpeg package with your package manager: sudo apt-get install ffmpeg
2. You can check you did it right by running ffmpeg -version

SoX Installation

1. Install the sox package with your package manager: sudo apt-get install sox
2. You can check you did it right by running sox

LaTeX Installation

1. Install texlive with your package manager by running the following commands:

sudo apt install texlive texlive-latex-extra texlive-fonts-extra texlive-latex-recommended texlive-science texlive-fonts-extra tipa

Note: this installation may take up a lot of space. The developers are working on providing a simpler, lighter LaTeX package for you to install

2. You can check you did it right by running latex

Arch/Manjaro

Before installing manim-community, there are some additional dependencies that you must have installed:

• Cairo
• FFmpeg
• Sox (optional, for sound)
• LaTeX (optional, for LaTeX)

Cairo Installation

1. Install the cairo package with your package manager: sudo pacman -S cairo

FFmpeg Installation

1. Install the ffmpeg package with your package manager: sudo pacman -S ffmpeg
2. You can check you did it right by running ffmpeg -version

SoX Installation

1. Install the sox package with your package manager: sudo pacman -S sox
2. You can check you did it right by running sox

sudo pacman -S texlive-most

Note: this installation may take up a lot of space. The developers are working on providing a simpler, lighter LaTeX package for you to install

2. You can check you did it right by running latex

Mac

Before installing manim-community, there are some additional dependencies that you must have installed:

• Homebrew
• Cairo
• FFmpeg
• Sox (optional, for sound)
• LaTeX (optional, for LaTeX)

Homebrew Installation

Homebrew is a package manager similar to apt on linux that allows you to install packages easily. If it is not installed, please install it with this command:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null

Cairo Installation

1. Run brew install cairo

FFmpeg Installation

1. Refer to the section on Brew installation to see how to install brew
2. Run brew install ffmpeg
3. You can check you did it right by running ffmpeg -version

SoX Installation

1. Refer to the section on Brew installation to see how to install brew
2. Run brew install sox
3. You can check you did it right by running sox

LaTeX Installation

1. Refer to the section on Brew installation to see how to install brew
2. Run brew cask install mactex
3. You can check you did it right by running latex

Note that MacTeX will require at least 4.5GB of hard disk space and bandwidth.

This is due to the fact that it installs every LaTeX addon package offered by CTAN. Only a few of these packages are required by Manim.

If you would like a smaller LaTeX install which only contains the packages needed by Manim alone, consider installing BasicTeX and suitable packages with the instructions below. This will require about 1.5 GB of space and bandwidth.

If you have installed MacTeX and are comfortable with it, do not install BasicTeX.

1. Refer to the section on Brew installation to see how to install brew
2. Run brew cask install basictex
3. Ensure that the TeXLiveManager tool tlmgr works, by running tlmgr --version in the terminal.
4. Run sudo tlmgr install standalone preview doublestroke relsize fundus-calligra wasysym physics dvisvgm.x86_64-darwin dvisvgm rsfs wasy cm-super
5. Ensure that LaTeX works by running latex in the Terminal.

Installing Manim-Community itself

Manim runs on Python 3.7+. If you'd like to just use the library, you can install it from PyPI via pip:

pip3 install manimlib

However, if you'd like to contribute to and/or help develop manim-community, you can clone this branch to your local device. To do this, first make sure you have git installed. Then, clone this repo by executing either

git clone git@github.com:ManimCommunity/manim.git

or

git clone https://github.com/ManimCommunity/manim.git

depending on whether you want to use HTTPS or SSH. Finally, run the following:

python3 -m pip install -r requirements.txt

Usage

To run your first example Scene, you can run the following commands:

For users:

1. Download the example_scenes/basic.py file from GitHub
2. Run the following command:

manim example_scenes/basic.py SquareToCircle -pl

For developers:

• Run the following command to install manim:

pip install -e .

• Then run the following command below:

manim example_scenes/basic.py SquareToCircle -pl

The -p flag in the command above is for previewing, meaning the video file will automatically open when it is done rendering. The -l flag is for a faster rendering at a lower quality.

Some other useful flags include:

• -s to skip to the end and just show the final frame.
• -n <number> to skip ahead to the n'th animation of a scene.
• -f to show the file in finder (for OSX).

You can also set MEDIA_DIR environment variable to specify where the image and animation files will be written.
