Hello,

I am preparing a figure in which I use \psRandom to add a selected number of dots to a rectangle.  However, I would like to use the same routine(s) with \psBall instead of dots because I want a 3D effect.  Is there a way to do this?  The basic code I am using is:

\psRandom[dotsize=4.5ex,dotstyle=Circle,linecolor=black,fillcolor=green!80!blue!30,randomPoints=2000,fillstyle=solid](16,17){
\psframe[linecolor=black](8.5,2.5)(13,10.5)}

but I would like to replace "dotstyle=Circle" with "dotstyle=\psBall" although I know that if it is possible to use \psBall, it isn't as simple as listed here.

Thank you.

Cheers,

Malcolm Field

Not possible with \psRandom, but:

\documentclass{article}
\usepackage{multido,pstricks-add,pst-slpe}
\begin{document}
	
\makeatletter
\pstVerb{
	\psk at randInit srand  % initializes the random generator
	/getRandReal { rand 2147483647 div } def } \makeatother
\begin{pspicture}(-1,-1)(11,11)
\psframe*[linecolor=black!10](-1,-1)(11,11)
\multido{\iA=0+1}{100}{%
	\psBall(! getRandReal 10 mul getRandReal 10 mul){blue}{3ex}} \end{pspicture}

\end{document}
