How to change the size of a point in pst-solides3d?

Question

In the following document, I want to decrease the radius of the sphere representing the point.

\documentclass{standalone}
\usepackage{pst-solides3d}
\begin{document}
\begin{pspicture}[viewpoint=30 40 30 rtp2xyz] (-2,-1) (2,2)
  \psSolid[object=point,
  args=0 0 0.5]
  \axesIIID (0,0,0) (1,1,1)
\end{pspicture}
\end{document}

I don't think there's a way to do this using the object=point key, which only takes the coordinates as arguments, but you can add points using \psPoint plus \psdots instead:

\documentclass{article}
\usepackage{pst-solides3d}
\begin{document}
\begin{pspicture}[viewpoint=30 40 30 rtp2xyz] (-2,-1) (2,2)
  \psSolid[object=point, args=0 0 0.5]
\psPoint(0,0,.25){P}
\psdotsdotsize=0.1
  \axesIIID (0,0,0) (1,1,1)
\end{pspicture}
\end{document}

Could you change this line? args=0 0 0.5] % the 0.5 value? – John Smith Nov 18 '23 at 22:14
@JohnSmith Not sure what you mean. The 0 0 0.5 is the x,y,z coordinates of the point. So .5 puts the point halfway up the z axis as shown in the image. – Alan Munn Nov 18 '23 at 22:16
