LaTeX의 3D 그림

Question

이 그림을 그리기 위한 좋은 패키지를 알려주실 수 있나요?

그리고 앞으로 묻고 싶은 것은 3D 플롯을 그리는 데 가장 효과적인 방법은 무엇입니까?

\documentclass[border=0.5cm]{standalone}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}
    % \draw [help lines] (0,0) grid (14,14);
    \draw (4,4) circle (2cm);
    \draw (2,4) arc (180:360:2cm and 1cm);
    \draw [dashed] (2,4) arc (180:0:2cm and 1cm);
    \draw [-latex,thick] (4,4) -- + (2,0) node [right] {$S_{0}$};
    \draw [-latex,thick] (4,4) -- + (0,2) node [above] {$S^{i}$};
    \draw [dashed] (4,4) -- + (-2,0);
    \node at (2,2.5) {$D^{-}$};
    \node at (2,5.5) {$D^{+}$};
    \node at (3,2.8) {$S^{i-1}$};
    \node at (4.9,5.2) {$x^{1}$};
    \node at (4.3,5.5) {$x_{0}$};
    \draw [-latex,thick] (7,4) -- + (1.5,0) node [above,midway] {$\Psi$};
    \draw (10,4.8) circle (0.8);
    \draw (10,3.2) circle (0.8);
    \node at (9,4) {$S_{0}$};
    \node at (11,5.5) {$S_{1}^{i}$};
    \node at (11,2.5) {$S_{2}^{i}$};
    \draw [-latex,thick] (11.3,2.8) -- + (30:1.5) node [midway,below] {$\beta$};
    \draw [-latex,thick] (11.3,5) -- + (-30:1.5) node [midway,above] {$\alpha$};
    \node at (13.5,3.8) {$(M,x_{0})$};
\end{tikzpicture}
\end{document}

편집하다: 여기서는 구 내부에 벡터를 추가했습니다. 그렇게하기 위해 나는\usetikzlibrary{intersections}
