Bonjour. Ich habe diesen Code für ein Kegelpendel. Ich möchte, dass es sich (gleichmäßige Rotation) durch die Ellipse bewegt. Wie kann ich den Code ändern?
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.pathmorphing,patterns}
\begin{document}
\begin{tikzpicture}[scale=1, decoration={coil,aspect=0.6,segment length=1.5mm,amplitude=1.5mm}]
\tikzset{ressort/.style={thick,gray,smooth}}
\draw[ressort,decorate] (0,0)--++(-2,+5);
\node at (-0.8,3) {$\ell$};
\draw [rounded corners=10pt,color=white,ball color=red,smooth] (0,0) circle (0.2);
\draw [xshift=0.3cm,rotate around={180:(-0.4,2.2)},line width=1pt,-stealth] (1.8,1.7) arc (-30:210:0.3cm and 0.2cm) node[below left=0.4cm] {$\omega$};
\draw[dotted](-2,0) ellipse (2cm and 0.6cm);
\draw (-2,-0.4)--++(0,5.4);
\fill [pattern=north east lines,rotate=0] (-2.5,5) rectangle (-1.5,5.3);
\draw[thick] (-2.5,5) --++ (1,0);
\end{tikzpicture}
\end{document}

Etwas wie das?

\usetikzlibrary{arrows.meta,bending,calc,decorations.pathmorphing,patterns}
\begin{document}

\path[use as bounding box] (-2.5,-0.9) rectangle (2.5,5.5);
\draw[dotted](0,0) circle[x radius=2cm, y radius=0.6cm];
\ifnum\X<180
\draw let \p1=($([yshift=1.2mm]\X:2cm and 0.6cm)-(0,5)$),\n1={veclen(\x1,\y1)} in

Mit kannst Du es ansehen Acrobat Reader. Dort kannst Du auch die Geschwindigkeit anpassen.
Wenn Sie die Bibliothek herunterladen tikzlibrary3dtools.code.texvonHierund legen Sie es irgendwo ab, wo TeX es findet, können Sie es kompilieren
