Document Classes ⇒ Parametric plot and infix postfix

[Dr. Rizzy]

Greetings,

I have two questions. The book I am learning about PSTricks on is The LaTeX Graphics Companion 2nd ed. In it it has no documentation of how to use parametricplotThreeD to render a surface that is plotted with two independent variables. The curve option does not work as this clearly has surface area. Also I am having trouble converting $ \frac{\sqrt{1+t^{2}}}{2} \cos(u) $ and $ \sqrt{1+t^{2}} \sin(u) $ to RPN (a.k.a. Postfix). If someone could direct me to a good Infix postfix coverter that would be great.

Perhaps the pst-infixplot package will help you with this task.

I am currently using MacTeX. How do I install pst-infixplot for this distribution if I am able? If I am not able is there another way? Also, what is the syntax to plot a surface in parametricplotThreeD[ "what goes here"]? Thank you very much for your help.

Open a command prompt and find out if the package is already installed.

Code: Select all

kpsewhich pst-infixplot.sty

If not, download the package as ZIP archive from CTAN [1]. You have to follow the guidelines of the TDS (TeX Directory Structure) when putting the single files into the directory tree. For the syntax of parametric 3D plots see the documentation of pst-3dplot.

[1] CTAN: directory: /tex-archive/graphics/pstricks/contrib/pst-infixplot

Have you upgraded to the MacTeX 2008 distribution? It comes with the new TeX Live Manager which makes very simple to install and update packages.

Thank you Juanjo and Localghost,

I am not sure if I do have that. If I do have that what would I do? Also, I forgot to tell you that I am trying to plot the function $ x=\frac{\sqrt{1+t^{2}}}{2} \cos(u), y=t, z=\sqrt{1+t^{2}} \sin(u) $ via parametricplotThreeD, do you know what I would put in parametricplotThreeD to plot this?

I am not sure if I do have that. If I do have that what would I do?

I recommend you to upgrade. It is really simple. Take a look at http://www.tug.org/mactex/
Concerning your question about parametricplotThreeD, I can't help.

use simply the algebaric option ...

Code: Select all

documentclass{article}
\usepackage{pst-3dplot}

\begin{document}

\begin{pspicture}(-3.25,-2.25)(3.25,5.25)
  \pstThreeDCoor[zMax=5]
  \parametricplotThreeD[xPlotpoints=200,linecolor=blue,%
    linewidth=1.5pt,plotstyle=curve,algebraic](0,31.4){%
    2.5*cos(t) | 2.5*sin(t) | t/6}
\end{pspicture}

\end{document}

that's all. No need for another package.
