PGFPlotsで3D図を作図する
optionsのymode,xmodeにnormal(default)を設定すると普通のplot、logを入れると対数目盛になる いくつかaliasがある
<coordinate system>
axis
なんか他にもあるっぽいな
legendの位置などを指定する座標とか
\usepgfplotslibrary{<library>}=\usetikzlibrary{pgfplots.<library>}
code:vector.tikz(tex)
\usepackage{pgfplots}
\usepackage{amsmath}
\begin{document}
\begin{axis}[
title={3D Rotation},
view={:azimuth}{:elevation}
:azimuth：z軸回転量
:elevation：x軸回転量
0でx-z平面表示になる
おそらくyが紙面手前向き
90でx-y平面表示
単位は度数
axisという新しい<coordinate system>が定義される
code:vector.tikz(tex)
view={60}{30},
axis lines=none,
ticks=none,
xmin=-30, xmax=50, ymin=0-30, ymax=50, zmin=0, zmax=50,
]

\node at(axis cs:0,0,{50/2}) anchor=east{$(\boldsymbol{r}\cdot\boldsymbol{n})\boldsymbol{n}$}; %
\draw-stealth,thick (axis cs:0,0,0) -- (axis cs:{30/2},{30*sqrt(3)/2},50); \node at(axis cs:{30/2},{30*sqrt(3)/2},50) anchor=west{$\boldsymbol{r^\prime}$}; %
\drawthin,gray (axis cs:0,0,50) circle (300); %
%
\draw-stealth,dashed (axis cs:0,0,50) -- (axis cs:{30/2},{30*sqrt(3)/2},50); \draw thin,->(axis cs:10,0,50) arc (0:60:100); \end{axis}
\end{tikzpicture}
\end{document}
改変：
\begin{center}を削除
code:rotate-object.tikz(tex)
