\section{Truncate a solid's vertices} The option \Lkeyword{trunc} allows us to \Index{truncate} a solid's vertices either globally or individually. This option uses the key \Lkeyword{trunccoeff} (value $0.25$ by default) which indicates the ratio $k$ used for the \Index{truncation} ($0<k\leq 0.5$). % \begin{itemize} \item \texttt{\Lkeyword{trunc}=\Lkeyval{all}} truncates all the vertices; \item \texttt{\Lkeyword{trunc}=0 1 2 3} truncates the vertices 0, 1, 2 and 3. \end{itemize} % \begin{LTXexample}[width=6cm] \psset{viewpoint=50 50 30 rtp2xyz,Decran=25,lightsrc=viewpoint} \begin{pspicture}(-3,-2)(2,2) \psSolid[ action=draw, object=cube, RotZ=30, trunccoeff=.2, trunc=all]% \end{pspicture} \end{LTXexample} \begin{LTXexample}[width=6cm] \psset{viewpoint=50 50 30 rtp2xyz,Decran=25,lightsrc=viewpoint} \begin{pspicture}(-3,-2)(2,2) \psSolid[action=draw, object=cube, RotZ=30, trunccoeff=.2, trunc=0 1 2 3]% \end{pspicture} \end{LTXexample} \endinput
