GeoGebra export to PGF/TikZ

This is very very cool. I used GeoGebra in my student research project
last year and had to export to EPS and postprocess with Corel Draw to
export to EPS again. PGF/TikZ support would have made it much easier to
generate nice graphics.

Dear List,

There are two months I started writing a PGF/TikZ export for the dynamic
geometry software GeoGebra. Now, you can try a preRelease here:

http://www.geogebra.org/cms/index.php?option=com_content&task=blogcategory&id=74&Itemid=59&lang=en

It supports Plain TeX, ConTeXt and LaTeX,

Thanks to tell me your opinion.

Best
Loïc

Fantastic !!!

It's very useful.

More, I think it's a very good way to learn how to use Tikz.

Thank's for this job !

Hi Loïc,

I'm glad there's another point in the intersection of the sets of  
"GeoGebra fans" and "PGF/TikZ fans"!

I tried it with a few of my ggb files and it looks very nice.  One of  
them, however, not so much.  Try the one linked here:

http://www.cims.nyu.edu/~leingang/content/geogebra

If I save it to TikZ, the generated image becomes off center so I  
can't see the right-hand side anymore.  I tried scaling it to 0.75cm,  
but then the circle got cut off around the edges (I think the clip  
command is at fault there).

Looking forward to a working product here.  Thanks!

Great work! I am not  familiar with GeoGebra, but the exported TikZ
looks nice and clean.
Maybe you could add some indentation for readability? Example:

\foreach \x in {-4,-3,-2,-1,1,2,3,4,5,6,7,8}
\draw[shift={(\x,0)},color=black] (0pt,2pt) -- (0pt,-2pt)node[below]
{\footnotesize \x};

I find it easier to read when it is written as:
\foreach \x in {-4,-3,-2,-1,1,2,3,4,5,6,7,8}
    \draw[shift={(\x,0)},color=black] (0pt,2pt) -- (0pt,-2pt)
node[below] {\footnotesize \x};

For readability you should also insert spaces in the node definitions.
Instead of:

... (-1.94,6)node[anchor=south west]{$a$};

output:

... (-1.94,6) node[anchor=south west] {$a$};
