# Make lines disappear, pst-solides3D [duplicate]

I'm drawing the following cylinder which represents a water flowing and cooling down

\documentclass[a4paper,10pt]{article}
\usepackage{pstricks}
\usepackage{auto-pst-pdf}
\usepackage{pst-solides3d}
\usepackage{xcolor}
\usepackage{epstopdf}
\usepackage[english]{babel} %change language if necessary
\usepackage[english,verbose]{layout}%change language if necessary

\begin{document}

\begin{pspicture}(-3,-4)(3,4)
\psset{viewpoint=50 50 20 rtp2xyz,Decran=50,lightsrc=viewpoint
}
\psset{color1=cyan,color2=red}
\psSolid[h=8,r=0.5, object=cylindre, ngrid=50 15, RotZ=30,
hue =1 0 0 0 0 1,linewidth=0.01pt ](0,0,-2.5)  \end{pspicture}

\end{document}


I would like the black lines to disappear, or atleast partially merge with the image. Is there anyway to perform this ?

Did you try to use 0pt for the line width? – Sigur Mar 30 '13 at 0:03
Yes, it makes white lines which are not really pretty. I have found a way though. Set linewidth = 0pt and plot a second cylinder on top of the first with a slightly different ngrid. – Mathusalem Mar 30 '13 at 8:09
@Mathusalem: linewidth=0pt is not the correct way. See my answer – Herbert Aug 3 '14 at 13:45

Use option grid:

\documentclass{article}
\usepackage{auto-pst-pdf}
\usepackage{pst-solides3d}
\begin{document}

\begin{pspicture}(-3,-4)(3,4)
\psset{viewpoint=50 50 20 rtp2xyz,Decran=50,lightsrc=viewpoint,
color1=cyan,color2=red}
\psSolid[h=8,r=0.5, object=cylindre, ngrid=50 15, RotZ=30,
hue =1 0 0 0 0 1,grid=false](0,0,-2.5)
\end{pspicture}
\end{document}
