在我的帖子中我的文档无法绘制角度,我把角度的绘制替换为
\tdplotdrawarc[color=blue]{(-0.25,-0.2,0)}{-0.3}{0}%
{55}{anchor=south east,color=black}{$\theta$}
这给了我一个附图

浏览 tikz-3dplot 手册时,很难弄清楚这些数字的含义,尤其是当人们试图快速完成某件事时。如果有人能指导我如何修改上面的代码,使 x 轴到 P 的角度为 theta,y 轴到 P 的角度为 phi,z 轴到 P 的角度为 psi,我将不胜感激。
完整代码如下:
\documentclass{article}
\usepackage{tikz}
\usepackage{tikz-3dplot}
\usetikzlibrary{arrows.meta, angles, quotes, decorations.pathreplacing,
datavisualization}
\begin{document}
\tdplotsetmaincoords{60}{110}
\begin{center}
\begin{tikzpicture}[>=latex,tdplot_main_coords,font=
\footnotesize,scale=1.5]
\begin{scope}[remember picture,rotate=45]
\coordinate (O) at (0,0);
\coordinate (R) at (2.5,2.5,0);
\coordinate (V) at (2.5,2.5,3);
\datavisualization [

\path (V) -- (R) coordinate[pos=.05](tl2);
\end{scope}
\draw[thick,->] (0,0,0)coordinate (O) -- (3,0,0) coordinate (X)
node[anchor=north east]{$x$};
\draw[thick,->] (0,0,0) -- (0,3,0) coordinate (Y) node[anchor=north
west]{$y$};
\draw[thick,->] (0,0,0) -- (0,0,3) coordinate (Z) node[anchor=south]{$z$};
\draw[thick,->,color=red,opacity=0.5] (0,0,0) -- (2.5,2.5,3) coordinate (V)
node[ right] {$P(\alpha,\beta,\gamma)$};
\draw[dashed,magenta!50] (2.5,2.5,3) -- (2.5,2.5,0) -- (0,0,0);
\draw[thick,blue!50] (2,0,0) -- (2.5,2.5,0);
\draw[thick,blue!50] (2.5,2.5,0) -- (0,2,0);
\draw[very thick,red!80!black,-{Triangle[fill=white]}] (0,0,0) --
(2,0,0)node [left=1ex] {$Q(\alpha,0,0)$} node[midway,left]{$\color{black}\alpha$};
\draw[very thick,red!80!black,-{Triangle[fill=white]}] (0,0,0) --
(0,2,0)node [above] {$Q^{'}(0,\beta,0)$} node[midway,above]{$\color{black}\beta$};
\draw[very thick,red!80!black,-{Triangle[fill=white]}] (0,0,0) --
(0,0,2)node [left] {$Q(0,0,\gamma)$};
\draw[dashed,red!80!black,-{Triangle[fill=white]}] (0,0,0) --
(2.5,2.5,0)node (b1)[right] {$R(\alpha,\beta,0)$};
\draw[dashed,red!80!black,-{Triangle[fill=white]}] (2.5,2.5,3) --
(2.5,2.5,0)node [left,yshift=2.75cm]{$\color{black}\gamma$};
\tdplotdrawarc[color=blue]{(-0.25,-0.2,0)}{-0.3}{0}%
{55}{anchor=south east,color=black}{$\theta$}
\tdplotdrawarc[color=blue]{(0,0.2,0)}{0.2}{0}%
{55}{anchor=south west,color=black}{$\phi$}
\tdplotdrawarc[color=blue]{(0,0,0.5)}{0.2}{0}%
{55}{anchor=south west,color=black}{$\psi$}
\end{tikzpicture}
\end{center}
\end{document}
这是我通过以下修改实现的
\tdplotdrawarc[thick,color=blue]{(.25,.15,.15)}{-0.60}{2}%
{175}{anchor=east,color=black}{$\color{blue}\theta$}
\tdplotdrawarc[thick,color=red]{(0.0,0.05,.1)}{-0.35}{1.5}%
{-95}{anchor=south west,color=black}{$\color{red}\phi$}
\tdplotdrawarc[thick,color=magenta]{(-0.1,-0.15,0.25)}{-0.45}{2.0}%
{-30}{anchor=south,color=magenta}{$\psi$}

这有效,但在我的文档中它给出了错误。我的序言部分是
\usepackage[dutch,english]{babel}
如果我输入英语、荷兰语,我的文档就是荷兰语。
\usepackage{tikz-3dplot}
\usetikzlibrary{shapes.geometric, decorations.pathreplacing, matrix, angles, quotes, arrows, arrows.meta, datavisualization}
我希望这能为我识别问题提供依据。
答案1
这是你想要的吗?
如果是这样,使用该库有什么问题angles
?它似乎对我有用:
