New Equation Editor and Keyboard

We’ve made some nice changes to our Chrome, Web and Tablet apps recently that many of you have been asking for. The first exciting feature is that the Input Bar in the Algebra View has expanded into a fully-fledged Equation Editor, for example:


and it also works fully with GeoGebra commands:


It’s now also much easier to add and edit matrices, parametric curves and piecewise-defined functions:


We’ve also added a touch-friendly on-screen keyboard that supports many languages and works nicely with our new equation editor:


You can try these cool new features in any of our web and tablet apps!

Fast, Beautiful LaTeX comes to GeoGebraTube

We’ve made a major change to GeoGebraTube and our Chrome App. We have updated the formula renderer (otherwise known as LaTeX renderer) to use the same version as in the desktop version. This means that mathematical formulas in our applets and web application will now look just as beautiful as they do in GeoGebra’s desktop version. This will work with all existing formula commands as well (for example TableText, FormulaText, FractionText, StemPlot).



Here’s an example of the new version using our new super-pretty formulas:

GeoGebra goes 3D

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 Superhero behind 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.

Some other highlights:

You can read about the full changes in the Release Notes.

Here are some 3D examples that you can try:

GeoGebra with 3D View

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.

Now, we are ready to show the first beta version of our new GeoGebra Chrome App with 3D View.

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.

Faster, Smaller GeoGebra Applets

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”.

GeoGebra Applet on PhoneOver 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 😉

GeoGebra Office App

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!
