GeoGebra étant utilisée par tous les
enseignants du secondaire, il faut stratégiquement
que nous développions un lien avec TeXmacs.
Ce sont des .xml zippés et l'on remplace l'extension .zip par .ggb.
Voici un exemple de figure :

En fichier annexe le code source xml de cette figure.
La taille est faible. Le fichier .ggb de cette figure pèse 8 Ko (taille générique des fichiers <8Ko sous mac os X).
Voici son code source.
Message de Markus le gérant de GeoGebra :
I think that an integration of GeoGebra into Texmacs would be very nice! Of course, our strength are dynamic figures and we only have a third party eps export library. However, I suggest to you start playing with this and keep in touch with our lead developer.
The first pistes turn around inserting a dead picture of the dynamic
GeoGebra figure. For this we use the GeoGebra « export to
picture » feature : the ggbeps export has
some bugs (see here). It seems that the eps export does
not have a long future... The ggb
png export is
perfect. The ggb
pdf is to verify but i can not
manage to insert any pdf in TeXmacs.
What do you think ? Could be a right format to
insert pictures into TeXmacs ?
Is the ggb eps or ggb
png
export via the command line planed ? Yes but for when ?
Now, there are at least 3 possibilities.
first possibility, currently available :
second possiblity with ggbeps export command
line :
third possibility by creating an environment around ggb
GeoGebra dispose d'un module de calcul formel.
Forum GeoGebra, août 2011 :
GeoGebra a changé son CAS. Ce n'est plus MathsPiper, ni Maxima. C'est maintenant MPReduce (implémenté en LISP).
