TikZでanimation
animate packageを使う
フレームごとにSVGが作られる
TikZでanimationする図を作ろうと検索したときに出てくる情報は全てこれ
animation (TikZ)を使う
svg animationのみ対応、PDF非対応
tikzjaxなどに使う分にはこれで十分

構文
sec-14.20 | Syntax for Path Specifications - PGF/TikZ Manual
:<animation attribute>={<options>}
[animate={myself:<animation attribute>={<options>}}]の略記法
正式な記法
[animate=<animation specification>]
<animation specification>に色々いれる
[animate={myself:<animation attribute>={<options>}}]は[animate={object=myself,attribulte=<animation attribute>,<options>}]の略記
これらの構文の詳しい同値関係はsection-anim-syntax-animate | Animations - PGF/TikZ Manualを参照
公式サンプルをいろいろ動かしてみる
<animation attribute>にanimationしたいoption nameを入れ、<options>に時刻とoption valueを指定するというかんじか
0s = "red", 2s = "blue"と複数点でoptionを指定すると、よしなにsmoothingしてくれる
例
shakeは指定した値で反復するように点を定めている
code:sample.tikz(tex)
\usetikzlibrary{animations}
\begin{document}
\tikz \draw :xshift = {0s = "0cm", 1s = "-15mm", repeats} (0,0) circleradius=5mm;
\tikzevery node/.style={fill, text = white}
\node (A) animate = {myself:fill = {0s = "red", 2s = "blue", repeats }} {Click me}
node text = white,anchor=north :fill = {0s = "red", 2s = "blue", repeats } at (A.south){Click me};
\begin{tikzpicture}[
animate/shake/.style = {myself:xshift = {
repeats,
0s = "0mm", 50ms = "#1", 150ms = "-#1", 250ms = "#1", 300ms = "0mm"
}}
]
\begin{scope}every node/.style={circle,fill = blue!20, draw=blue,very thick}
\node (A) animate = {shake = 1mm} {Shake};
\node at (A.east) anchor=west,animate = {shake = 2mm} {SHAKE};
\end{scope}
\end{tikzpicture}
\begin{tikzpicture}[
shake/.style={animate={myself:xshift = {
repeats,
0s = "0mm", 50ms = "#1", 150ms = "-#1", 250ms = "#1", 300ms = "0mm"
}}}
]
\begin{scope}every node/.style={circle,fill = blue!20, draw=blue,very thick}
\node (A) shake = 1mm {Shake};
\node at (A.east) anchor=west,shake = 2mm {SHAKE};
\end{scope}
\end{tikzpicture}

animationの起動方法section-anim-timeline | Animations - PGF/TikZ Manual
repeats：繰り返し
pgf./tikz/animate/options/repeats | Animations - PGF/TikZ Manual
begin on=click：クリックで開始
pgf./tikz/animate/options/begin:on | Animations - PGF/TikZ Manual
animate/<style name>/.style={myself:<animation attribute>={<options>}}でanimation styleを定義すると、animate = {<style name>}で使えるようになる
通常のstyle (TikZ)記法を使うと
<style name>/.style={animate={myself:<animation attribute>={<options>}}}で定義
<style name>で使用
となる
