# What is the difference between pscurvepoints and curvepnodes?

What is the difference between \pscurvepoints (in pstricks-add) and \curvepnodes (in pst-node)?

\documentclass[pstricks]{standalone}
\usepackage{pst-node}
\usepackage{pst-plot}
\begin{document}
\pstVerb{realtime srand}%
\psLoop{25}{%
\begin{pspicture}(-2,-2)(2,2)
\pscircle*[linecolor=orange]{0.75}
\curvepnodes[plotpoints=100]{0}{360}{rand 16 mod 90 div 1.50 add t PtoC}{P}
%\pscurvepoints[plotpoints=100]{0}{360}{rand 16 mod 90 div 1.50 add t PtoC}{P}%==== option 2
\def\points{}%
\multido{\i=0+1}{\Pnodecount}{\xdef\points{\points (P\i)}}
%\multido{\i=0+1}{\Ppointcount}{\xdef\points{\points (P\i)}}%==== option 2
\expandafter\psccurve\points
\end{pspicture}}
\end{document}


When I enable the lines with option 2 in comment and disable the corresponding lines, I just get a yolk.

\pspolylineticks refers to \pscurvepoints. That is the only difference.
• What is the relationship between the plotpoints representing the number of vertices prepared by pscurvepoints and the last argument of \pspolylineticks representing the number of ticks? The documentation is confusing. Jul 4, 2013 at 11:19
• \pspolylineticks uses \<NodePrefix>pointcount which is only defined by \pscurvepoints
• What is the relationship between plotpoints=\<nodeprefix>pointcount and the last argument of \pspolylineticks? In other words, why do we need to specify the last argument of \pspolylineticks? Jul 4, 2013 at 11:34
