如何pst-3dplot将对象的不透明度设置为透明？我有一个例子，其中使用opacity或strokeopacity选项不起作用。我试图制作类似于以下的图像：
希望展示球体内部的更多细节，例如：
但是，我无法让球体的顶部通过不透明表面看起来与底部不同，或者让球体透明以看到内侧的线条/标记。
这是我尝试过的（在 TeXWorks 中使用 XeLatex+MakeIndex+BibTex 进行编译）：
\documentclass{article}
\usepackage{pst-3dplot}

\def \cylLength {5}
\def \planeLen {5}
\FPeval{\theta}{pi/4}
\FPeval{\b}{radius*cos(theta)}
\FPeval{\a}{radius*sin(theta)}
\FPeval{\h}{radius-radius*cos(theta)}

更新： Herbert 的回答很好，并涵盖了该图的许多要点，但由于他的回答指出该包不隐藏线，因此我想换个话题。此外，我希望顶面的颜色与底面不同，并且交叉区域的颜色也不同。
所以这就是我目前所拥有的，现在有不同的问题，我将提出其他问题或在这里更新，以满足未来对这个问题的兴趣。

当前版本http://texnik.dante.de/tex/generic/pst-3dplot/pst-3dplot.tex考虑opacity和的值：strokeopacity
\begin{pspicture}(-4,-2.25)(2,4.25)
\psset{Alpha=45, Beta=10}
\pstThreeDCoor
\pstThreeDLine[linewidth=2pt,linecolor=blue,arrows=->] (0,0,0)(0,0,\b)
\pstThreeDLine[linewidth=2pt,linecolor=blue,arrows=->] (0,0,0)(0,\a,\b)
\pstThreeDLine[linewidth=2pt,linecolor=green] (0,0,\b)(0,\a,\b)
\pstThreeDLine[linewidth=2pt,linecolor=black] (0,\a,\b)(0,\radius,\radius)
\pstThreeDSquare[fillcolor=blue!40,fillstyle=solid,opacity=0.4](-5,-5,\planeLocRatio)(0,10,0)(10,0,0)
\pstThreeDSphere[opacity=0.3,strokeopacity=0.3,linewidth=0.1pt](0,0,0){\radius}
\end{pspicture}
但是，如果您想要隐藏线和表面，则使用“pst-solides3d”。
