「LaTeX数式」埋込みアニメーション描画環境 Manimを、Dockerコンテナの中で動かして成功した件（Macbook環境編）

Last updated at Posted at 2020-12-28

#環境

  • OS: macOS Catalina
  • Docker: Docker version 20.10.0, build 7287ab3

###MacbookにDockerをインストールしてmakeする手順は、以下を参照ください。

###作成したMP4ファイル

（ Qiitaのこの記事に動画ファイルをアップロードするにあたり、ffmpegコマンドでMP4ファイルをGIFファイルに変換しました。 ）

（ OpeningManimExample.mp4 ）

Opening__ManimExample.gif

（ WriteStuff.mp4 ）

WriteStuff.gif

###生成したLaTeX埋め込み動画ファイル （MP4ファイル）
#####（docker cpコマンドを使って、Dockerコンテナの中から、Macbookのlocalに、コピーしたファイル）

Terminal
ocean@AfoGuardMacBook-Pro ~ % ls ./files_from_docker

####jasonkwan/manimをdocker pullして使いました。

###Manim Docker Container

This container is based on eulertour/manim, except that it has oh-my-zsh and the Powerlevel10k theme and tmux, so that you can easily run parallel interactive manim renderings in your terminal window. Manim is a Python 3-based animation pipeline written by Grant Sanderson of the 3blue1brown YouTube channel. It is not incredibly well documented, so at some point I may add a tutorial here. For now, here are some barebones instructions on using the Docker container:

Start the Docker container, making sure that you mount the host directory that holds your scene code. For example:

docker run -it --rm -v /host/scene/dir:/scenes jasonkwan/manim:latest

###docker pullでdockerイメージをインストール

Terminal
ocean@AfoGuardMacBook-Pro ~ % cd Desktop 
ocean@AfoGuardMacBook-Pro Desktop % docker pull jasonkwan/manim

"docker cp" requires exactly 2 arguments.
See 'docker cp --help'.

Usage:  docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH|-
	docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PATH

Copy files/folders between a container and the local filesystem
