Phew! We’ve had to rewrite pretty much the whole of GeoGebra to achieve this, and we’ve had to do this while doing other cool things like HTML5 & the CAS View but finally we’re ready to release GeoGebra 5 with 3D.
Mathieu “3D Superhero” Blossier
The 3D Superherobehind all this is of course Mathieu Blossier who has been coding and coordinating from his poky attic room in Rouen since 2008 and as they say “When the going gets tough, the tough get going” which definitely applies to Mathieu.
There have already been many benefits to 2D GeoGebra behind the scenes from the 3D work. For example in GeoGebra 4 we added the Point in Object tool so that Points could be placed on Polygons in 3D later on.
As usual our wonderful translators have been working hard ready for the release so GeoGebra 5 is already available in all the usual languages.
As you may know we have been working on adding the 3D View to GeoGebra for a long time now. It’s been a much longer journey than we first imagined. In particular since 2008, the need has arisen to have 3D working first in Java (JOGL), and then with WebGL / HTML5 technologies.
Of course we’re still developing the Java desktop version alongside and GeoGebraTube will support displaying 3D files using WebGL / HTML5 as well. Our 3D applets already work on devices with Android 4.4 (and Android 4.3 devices supporting WebGL), for example, Nexus 7 Phones and Nexus 10 Tablets. If you have an iPad you will have to wait for iOS 8 to be released later this year to use our 3D applets on GeoGebraTube.
We were very pleased with how the switch to HTML5 on GeoGebraTube went at the end of last year, and with how the community responded by helping each other to sort out the minor changes from our Java to HTML5 applets, eg changes needed to LaTeX. But as you know, we’re always working to make GeoGebra better, faster & more fun each year and we’ve never sat back and thought “it’s finished”.
Over the last year we’ve been working on a top-secret project to improve GeoGebraTube which is now ready for its first public showing. At the moment a typical HTML5 applet downloads over 3MB when it’s first run and starts up in about 3s (on a fast computer). With our new “GeoGebra Applet Compiler” technology, the same applet downloads only about 0.4MB and starts up in 0.8s on the same machine. In addition our compiled applets run much more smoothly even on slower devices and support retina resolutions on iPhone 4, 5, iPad 3, 4, Nexus 7, Nexus 10 etc.
Try some example applets using our new GeoGebra Applet Compiler:
There are a few limitations about what will work with the new applet compiler (we’ll release details later) and it will only work inside GeoGebraTube, so we will still continue to improve and support our other versions of GeoGebra as well, of course. Our goal is to make these new faster and smaller GeoGebra applets the default for most materials on GeoGebraTube automatically in the background without you having to do anything. We will keep you posted
With our new GeoGebra Office App, you can now easily include interactive GeoGebra worksheets in Microsoft Word. You can search GeoGebraTube and will get a nice preview image of the worksheet in your document after pressing the “insert” button. Just click the play button to open it in a popup window and enjoy GeoGebra’s full interactivity!
GeoGebra 4.4 will be released on 1st December 2013. The main change is that the CAS View is much better & faster. You can already try our Release Candidate.
On 1st of December, we will also switch GeoGebraTube to “HTML5 preferred”. This means that we will display materials using our HTML5 applets by default where possible, and deliver Java applets only for older browsers (like Internet Explorer 8). There are a few advanced things that are not fully supported in our HTML5 applets yet (e.g. some LaTeX commands), so please check your GeoGebraTube worksheets by clicking on “View as HTML5 Applet”. If you need help updating your worksheets, please ask in the forum. We have also added an option in GeoGebraTube to set the preferred applet type, so you can e.g. force an applet to still be shown in Java (Edit Material -> Advanced Settings -> Preferred Applet Type -> Default/HTML5/Java), however the future is definitely HTML5
If you are hosting GeoGebra applets on your own website, please see this important announcement to make sure these applets will continue to work well in the future also.
GeoGebra and our friends at Wikispaces got together to make using GeoGebra in your Wikispaces classroom fun and easy with our new GeoGebra widget!
Why do we like Wikispaces so much? Well, its probably because they are a lot like GeoGebra and our community! Wikispaces is one of those amazing free resources that actually makes teaching and learning easier, interactive, and social. Hmmm, sound familiar?
Not only is Wikispaces probably the best wiki tool available to teachers and students everywhere, it has also inspired a generation of collaborative learners, with as many as 35 million visitors to Wikispaces every month. That’s what we call a critical mass of learning power! Now… mix in a little GeoGebra and what have you got?…dynamic STEM teaching and learning wiki pages everywhere!
Want to read more? Check out what they are saying about GeoGebra on the Wikispaces blog. It’s not only pretty flattering about our community, but also tells you how to get started using the GeoGebra widget on a Wikispaces Classroom page of your own.
Of course, this is only the start to a great new chapter for GeoGebra, and we have lots of plans on how to continuously improve and extend our apps. As always, please let us know your feedback and ideas in our user forum and continue to build the world’s best math tool together.
On August 3 and 4, over 350 mathematics educators, teacher educators, mathematicians, and students converged on Miami University in Oxford, Ohio, USA for the 4th Annual North American GeoGebra Conference. This is the third year in a row the GeoGebra Institute of Ohio has hosted a free summer conference (Midwest Regional GeoGebra Conference), and the first year for hosting the North American Conference.
Attendees came from across North America and as far away as New Zealand. The conference featured over 50 content-based sessions. In addition to the content sessions, participants who were interested in learning how to use GeoGebra could have attended a 2-day “Newbie” workshop. Participants could also have attended a day-long strand on Digital Ethics, featuring sessions on privacy rights, ethics of digital games, and other digital issues.
The conference was opened by Keynote speaker John Golden from Grand Valley State University. Slides from John’s presentation – Teaching for Creativity – can be downloaded at http://bit.ly/goldenggb13. You can follow John on Twitter @mathhombre.
In addition to the host GeoGebra Institute of Ohio, four other North American Institutes were represented at the conference:
GeoGebra Institute of Maine (James Quinlan)
GeoGebra Institute of Minnesota (Dave Pugh)
GeoGebra Institute of Central Florida (Janet Andreasen, Erhan Selcuk Haciomeroglu, and Maria Capursi)
GeoGebra Institute of South Florida (Ed Knote)
GeoGebra Institute of Canada (Geoff Roulet and Jill Lazarus)
