我想绘制这个三角形绕oz轴的旋转动画，并固定框架(x_0，y_0，z_0)

我想制作一个动画，来展示这个盘子绕轴 oz 的旋转，我用了这个代码

\documentclass[border=5pt]{standalone}
\usepackage{tikz,tikz-3dplot}
\begin{document}
\tdplotsetmaincoords{70}{110}% deu angle $\theta_d$ atour de (x) et $\phi_d$ autour de (z)
\begin{tikzpicture}[tdplot_main_coords,scale=5]

  \pgfmathsetmacro{\r}{.5}
  \pgfmathsetmacro{\O}{45} % right ascension of ascending node [deg]
  \pgfmathsetmacro{\i}{45} % inclination [deg]
  \pgfmathsetmacro{\f}{45} % true anomaly [deg]

  \coordinate (O) at (0,0,0);

  \draw [thick,->] (O) -- (1.5,0,0) node[anchor=north east] {$x_0$};
  \draw [thick,->] (O) -- (0,1,0) node[anchor=north west] {$y_0$};
  \draw [thick,->] (O) -- (0,0,1.5) node[anchor=south] {$z_0$};
  \fill[black, tdplot_main_coords] (0,0,0) circle (0.5pt)node[medway, anchor=-30]{$O$};

  \tdplotsetthetaplanecoords{45}
  \draw [thick,tdplot_rotated_coords,color=violet,->] (O) -- (1.5,0,0) node[anchor=north east] {$z$};
  \draw [thick,tdplot_rotated_coords,color=violet,->] (O) -- (0,1.65,0) node[anchor=north west] {$x$};
  \draw [thick,tdplot_rotated_coords,thick,dashed, color=violet,->] (O) -- (0,0,1) node[anchor=south] {$y$};

  \draw [tdplot_rotated_coords, fill=yellow!20!gray] (O) -- (1,0,0)--(0,1,0)--cycle; 

  \tdplotdrawarc[thick, tdplot_main_coords, color=red, ->]{(0,0,0)}{\r}{0}{45}{anchor=105}{$\varphi$}
   \tdplotdrawarc[thick, tdplot_main_coords, color=red, ->]{(0,0,0)}{\r}{90}{135}{anchor=180}{$\varphi$}
\end{tikzpicture}
\end{document}

以 3D 形式制作如上图所示的图形，但我还不熟悉使用 animate 包制作乳胶动画。 在此处输入图片描述 有人能帮我做这个吗？提前谢谢了。

只需按照 Ignasi 的链接并进行一些小调整即可

\documentclass[border=5pt]{standalone}
\usepackage{tikz,tikz-3dplot}
\usepackage{animate}

\begin{document}

\begin{animateinline}[loop, poster = first, controls]{24}
  \multiframe{36}{iAngle=0+10}{
   \tdplotsetmaincoords{70}{110}% deu angle $\theta_d$ atour de (x) et $\phi_d$ autour de (z)
\begin{tikzpicture}[tdplot_main_coords,scale=5]
\useasboundingbox[tdplot_screen_coords] (-2.3,-0.6) rectangle (2.3,2);
% adapted from https://tex.stackexchange.com/a/315853/121799
  \pgfmathsetmacro{\r}{.5}
  \pgfmathsetmacro{\O}{45} % right ascension of ascending node [deg]
  \pgfmathsetmacro{\i}{45} % inclination [deg]
  \pgfmathsetmacro{\f}{45} % true anomaly [deg]

  \coordinate (O) at (0,0,0);

  \draw [thick,->] (O) -- (1.5,0,0) node[anchor=north east] {$x_0$};
  \draw [thick,->] (O) -- (0,1,0) node[anchor=north west] {$y_0$};
  \draw [thick,->] (O) -- (0,0,1.5) node[anchor=south] {$z_0$};
  \fill[black, tdplot_main_coords] (0,0,0) circle (0.5pt)node[midway, anchor=-30]{$O$};

  \tdplotsetthetaplanecoords{\iAngle}
  \draw [thick,tdplot_rotated_coords,color=violet,->] (O) -- (1.5,0,0) node[anchor=north east] {$z$};
  \draw [thick,tdplot_rotated_coords,color=violet,->] (O) -- (0,1.65,0) node[anchor=north west] {$x$};
  \draw [thick,tdplot_rotated_coords,thick,dashed, color=violet,->] (O) -- (0,0,1) node[anchor=south] {$y$};

  \draw [tdplot_rotated_coords, fill=yellow!20!gray] (O) -- (1,0,0)--(0,1,0)--cycle; 
  \pgfmathtruncatemacro{\iBngle}{\iAngle+90}
  \tdplotdrawarc[thick, tdplot_main_coords, color=red,->]{(0,0,0)}{\r}{0}{\iAngle}{anchor=105}{$\varphi$}
   \tdplotdrawarc[thick, tdplot_main_coords, color=red, ->]{(0,0,0)}{\r}{90}{\iBngle}{anchor=180}{$\varphi$}
\end{tikzpicture}
  }
\end{animateinline}
\end{document}
