如何在 Tex 中创建动态几何文件？

我有一个包含

\documentclass[10pt]{article}
\usepackage{pgf,tikz}
\usetikzlibrary{arrows}
\pagestyle{empty}
\begin{document}
\definecolor{uququq}{rgb}{0.25,0.25,0.25}
\definecolor{tttttt}{rgb}{0.2,0.2,0.2}
\begin{tikzpicture}[line cap=round,line join=round,>=triangle 45,x=1.0cm,y=1.0cm]

文件是在 GeoGebra 程序中编写的，我将其上传到http://www.mediafire.com/?r61yp96mwlm3t1h

如何像在 GeoGebra 中一样在 Tex 中创建一个点 M 在圆上移动的文件？

在此处输入图片描述

可点击的 PDF 动画，作为演示的修改版本创建inlinemovie.tex：

\documentclass{article}
\usepackage{lmodern}
\usepackage[inline]{asymptote}
\usepackage{animate}
\begin{document}

Here is an inline PDF movie, generated with the commands
\begin{verbatim}
pdflatex inlinemovie
asy inlinemovie-*.asy
pdflatex inlinemovie
\end{verbatim}
or equivalently,
\begin{verbatim}
latexmk -pdf inlinemovie
\end{verbatim}

\begin{center}
\begin{asy}
import markers;
import animate;
animation Anim=animation("movie1");
real phi;

picture pic;
size(pic,300);

for(int i=0; i < 40; ++i) {
  phi=100-2*i;
  guide circ1=circle((5,0),1);
  guide circ2=circle((2,0),2);
  guide circ3=circle((3,0),3);
  guide circ4=circle((4,0),4);

  pair A,B,C,D,G,H,I,J,M,NN;
  pair AMp;
  A=(0,0); B=(8,0); D=(2,0);
  C=(4,0); I=(6,0);

  M=shift(D)*rotate(phi)*(2,0);
  AMp=0.5(A+M);

  guide AM=M--(M+dir(M-AMp)*10);
  NN=intersectionpoint(AM,circ4);
  H=0.5(M+NN);
  J=0.5(H+B);

  draw(pic,A--C); 
  draw(pic,A--M);
  draw(pic,M--NN,StickIntervalMarker(2,1,angle=-20,red,dotframe(black)));
  draw(pic,C--B,StickIntervalMarker(2,2,angle=-20,darkgreen,dotframe(black)));
  draw(pic,H--B,StickIntervalMarker(2,3,angle=-20,blue,dotframe(black)));

  draw(pic,J--C);
  draw(pic,H--C);
  draw(pic,H--I);

  label(pic,"$H$",H,NW);
  G=intersectionpoint(J--C,H--I);

  dot(pic,A);
  dot(pic,B);
  dot(pic,C);
  dot(pic,D);
  dot(pic,M);
  dot(pic,NN);
  dot(pic,G);
  dot(pic,H);
  dot(pic,J);
  label(pic,"$A$",A,W);
  label(pic,"$B$",B,E);
  label(pic,"$C$",C,SW);
  label(pic,"$D$",D,N);
  label(pic,"$M$",M,NW);
  label(pic,"$N$",NN,dir(M-A));
  label(pic,"$G$",G,S);
  label(pic,"$H$",H,NW);
  label(pic,"$I$",I,SE);
  label(pic,"$J$",J,NE);

  draw(pic,circ1);
  draw(pic,circ2);
  draw(pic,circ3);
  draw(pic,circ4);

  Anim.add(pic);
  erase(pic);
}
label(Anim.pdf("controls",delay=50,keep=!settings.inlinetex));
\end{asy}
\end{center}

\end{document}
