[pstricks] object vecteur arrowhead size

Use an argument vector, in addition to coordinates, the radius and height of the cone :
args={x y z [r h]}


\documentclass{article}
\usepackage{pst-solides3d}
\begin{document}
\begin{pspicture}[showgrid=true](-5,-5)(5,5)
    \psset{viewpoint=30 10 20, lightsrc=viewpoint, Decran=100}
    \axesIIID(0,0,0)(3,3,3)
    \defFunction{spacecurve}(t){t Sin}{t 2 mul Sin}{t 3 mul Sin}        
    \psSolid[object=courbe,
        r=0,
        range=0 2 pi mul,
        linecolor=blue,
        linewidth=0.01,
        resolution=720,
        function=spacecurve]    
    \multido{\nx=1.50+0.20}{5}{
        \psSolid[object=vecteur,
            args={\nx\space Sin \nx\space 2 mul Sin \nx\space 3 mul Sin [0.05 0.1]},
            linecolor=red]}    
\end{pspicture}
\end{document}






Best regards,

Manuel

Sujet : [pstricks] object vecteur arrowhead size


All:  Is there anyway to control the size of the arrowhead in pst-solide3d?  The 
following example shows a space curve and some vectors. The arrowheads are too 
large.  Thanks, Jon.
