The command Surface[] is very usefull but I think the 3D motor of Geogebra5 is false.It lacks a rotation, the rotation around the y axis.

Great!Yes, it is now possible.
What you will see by clicking on the images, it is a GGB file developed with Geogebra5 (3D) and exported in html5 file. Incredible

3D Klein bottle in an html export of Geogebra 4.4

The topic is this post is not the 3Dklein bottle with Geogebra 4.4 but the fact that we can still export the Ggb file with version 4 (see protocole below)

Click on the picture to launch the applet (Geogebra 4.4)
Click here to download this applet here
 
Protocole 1: copy this part of code in your htlm page with a text editor and change the name of the  ggbfile

<applet name="ggbApplet" code="geogebra.GeoGebraApplet" codebase="./" archive="geogebra.jar" height="620" width="1240"><param name="filename" value="klein.ggb"> <param name="framePossible" value="true"> <param name="showAlgebraInput" value="false"> <param name="showMenuBar" value="true"> <param name="showResetIcon" value="true"> <param name="showToolBar" value="true"> <param name="showToolBarHelp" value="true">Sorry, the
GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and


active in your browser (
<a href="http://java.sun.com/getjava">Click
here to install Java now</a>) </applet>

Protocole 2: Use an old ggb file in html , you could see a part of this code and change the name of the ggb file. Save as an other name in htlm.


Otherwise if you want to have your ggb file in html5 on your site and not on Geogebratube, you must use Base64 or more simply use geogebratube to make html5 file,then downlod your file on your own site and delete the file on Geogebratube(see exemple here on my site by following this link:

Voeux pour 2014

 Je tiens à informer toutes les personnes qui m'ont envoyé l’année dernière des messages promettant bonheur, fortune, prospérité et santé en 2013
que : ÇA N'A PAS MARCHÉ !!!!
Alors, en 2014, pour cette nouvelle  année, envoyez-moi directement l'argent !
J’accepte aussi les bouteilles de bon vin, les bons repas  et toutes les offrandes.
MERCI    :=)
