30 请问这种图形怎么在Latex画出来

您好！这个图能不能请您写一下代码呢？

一直没有注意到这个问题，今天用tkz-euclide凑了一个(椭圆)：

\documentclass[margin=3pt]{standalone}

\usepackage{tkz-euclide}

\begin{document}

\begin{tikzpicture}
  \tkzDefPoint(-2,0){O}
  \tkzDefPoint(1,6){J}
  \tkzDefMidPoint(O,J)
  \tkzGetPoint{I}
  \tkzInterCC(J,I)(I,J) \tkzGetPoints{L}{H}
  \tkzInterCC(O,I)(I,O) \tkzGetPoints{K}{G}
  \tkzInterLL(O,K)(J,H) \tkzGetPoint{M}
  \tkzInterLL(O,G)(J,L) \tkzGetPoint{N}
  \tkzDefPointsBy[symmetry=center J](L,H){D,E}
  \tkzDefPointsBy[symmetry=center O](G,K){C,F}
  \tkzDefMidPoint(O,C)
  \tkzGetPoint{P}
  \tkzDefPointOnCircle[through = center J angle 30 point E]
  \tkzGetPoint{A}
  \tkzDefLine[tangent at=A](J)
  \tkzGetPoint{h}
  \tkzDefLine[orthogonal=through A](h,A) \tkzGetPoint{a}
  \tkzDefLine[orthogonal=through O](A,h) \tkzGetPoint{b}
  \tkzInterLL(O,b)(A,h) \tkzGetPoint{B}
  \tkzDefPointOnLine[pos=0.15](O,A)\tkzGetPoint{A'}
  \tkzDefPointOnLine[pos=0.15](O,B)\tkzGetPoint{B'}

  \tkzSetUpLine[line width=2pt]
  \tkzDrawLines[add=12.5 and 2.5](A,h)
  \tkzDrawLines[-Latex, add=0 and 1.5](A,a)
  \tkzDrawSegment[blue,dash pattern = on 6pt off 3pt on 1pt off 3pt on 1pt off 3pt](O,B)
  \tkzDrawSegment[green,dashed](O,A)
  \tkzDrawSegment[-Latex,green](O,A')
  \tkzDrawSegment[-Latex,blue](O,B')
  \tkzDrawCircles[line width=2pt](O,P)
  \tkzDrawArc[line width=2pt,delta=0,orange](N,D)(C)
  \tkzDrawArc[line width=2pt,delta=0,orange](M,F)(E)
  \tkzDrawArc[line width=2pt,delta=0,orange](J,E)(D)
  \tkzDrawArc[line width=2pt,delta=0,orange](O,C)(F)
  \tkzMarkRightAngles(a,A,B h,B,O)

  \tkzLabelPoint[below left](O){$O$}
  \tkzLabelPoint[above](A){$A$}
  \tkzLabelPoint[above right](B){$B$}

  \tkzText[below right=20pt](M){$K$}
  \tkzText[above=60pt](O){$\mathcal{S}^{n-1}$}
  \tkzText[below left=60pt](J){$\rho(K,v)$}
  \tkzText[shift={(-20pt, 70pt)}](A){$H_{u,t}$}
  \tkzText[shift={(80pt, 20pt)}](A){$u=\alpha^{*}_{K}(v)$}
  \tkzText[shift={(60pt, -60pt)}](B){$u$}
  \tkzText[shift={(10pt, -10pt)}](O){$u$}
  \tkzText[shift={(0pt, 10pt)}](O){$v$}
  \draw [red, decorate,decoration={brace, amplitude=80pt},
         xshift=4pt,yshift=0pt]
         (B) -- (O) node[black,midway,shift={(80pt, -80pt)}]
         {$h(K,u)$};
\end{tikzpicture}

\end{document}

结果为：
