Graphics, Figures & Tables ⇒ pst-3dplot | Different Viewpoint Angles for two Figures

[nordbeck]

Hi!

When I have two (or more) pst-3dplot figures on the same page, it does not matter what values i give the parameters Alpha and Beta (using \psset) in the second figure. Instead the values given in the first figure will be used. I guess this is a bug. Anyone that knows how to fix it?

Thanks!

Hi Patrik,

welcome to the board!

The question is quite abstract. Perhaps post a minimal working example with such two figures. We could test it, figure out if it's a bug and perhaps provide a fix.

Thanks for your quick response!

I have not figured out how to include code nicely (sorry for that!), so i hope my "copy and paste" will work. Here the parameter "Alpha" in the second pspicture do not work. If you active \pagebreak (take away %), then it works. Further, if you skip the \pstThreeDCorr line in the first pspicture, then it works without pagebreak. Seems very strange to me! Do you get the same result? Hope you see what I mean.

Thanks again!
Patrik

Code: Select all

\documentclass{article}
\usepackage{pst-3dplot,pstricks-add}

\begin{document}
  \begin{pspicture}(0,0)(5,5)
    \psset{Alpha=125,Beta=20}%
    \pstThreeDCoor[xMin=-1,xMax=4,yMin=-1,yMax=4,zMin=-1,zMax=3,linecolor=black, nameX=$ $, nameY=$ $,nameZ=$ $]%
  \end{pspicture}

%  \pagebreak[4]

  \begin{pspicture}(0,0)(5,5)
    \psset{Alpha=155,Beta=12}%
    \parametricplotThreeD[xPlotpoints=200,linewidth=0.6pt,plotstyle=curve,linestyle=dashed](25,205){t cos 3 mul t sin 3 mul 0}%
    \parametricplotThreeD[xPlotpoints=200,linewidth=0.6pt,plotstyle=curve,linestyle=solid](205,385){t cos 3 mul t sin 3 mul 0}%
    \parametricplotThreeD[xPlotpoints=200,linewidth=0.6pt,plotstyle=curve](-1,1){t 25 cos mul 3 mul t 25 sin mul 3 mul 1 t t mul sub sqrt 3 mul}%
  \end{pspicture}
\end{document}

Hi Patrik,

I got this output:

plot.png (4.29 KiB) Viewed 3893 times

Do you get different pictures?

I used pst-3dplot.tex 2011/03/01 v1.94. Which one are you using? You can see it in the .log file if you add \listfiles to your preamble.

Hi again!

No, I do not get your output; yours is correct (my second figure is viewed with \Alpha=125 and not \Alpha=150 as it should). I use the same version of pst-3dplot. It seems to be the \pstThreeDCoor in the first figure that is the problem. I can write other commands there without affecting the second figure.

If it is of any use I use MiKTeX 2.9 on Windows XP.

Thanks again for your help!

Hi again!

We found out a "solution" to our problem. Put the \pstThreeDCoor line first, before the other commands. Also put a \pstThreeDCoor line in every picture on the page; if you don't want it, write linecolor=white.

Strange that Stefan_K did not experience the same problem, I still think it is a bug somewhere.

Thanks!

A bug is most likely. And to my astonishment I get the false output with the most current version pst-3dplot.tex 2012/06/07 v1.97 `PST-3dplot' (hv) (see attachment). So this is definitely worth a note to the package maintainer. Actually he is a member of this this board, but you should nevertheless drop him a line.
