You can also review [http://wiki.laptop.org/go/DrGeo#How_to_use_DrGeoII.3F_.28video_screencast.29 the screencasts below] to know more about these new features.

== What is Dr. Geo? What is interactive geometry?==
* From the [http://www.ofset.org/drgeo Dr. Geo 1.1 website]: ''Dr. Geo allows one to create geometric figure plus the interactive manipulation of such figure in respect with their geometric constraints. It is usable in teaching situation with students from primary or secondary level.''

* Dr. Geo II integrates advanced features as an integrated Smalltalk programming language to define scripts within a figure. The language is also used to define functionally interactive figure.

* Dr. Geo II is an interactive geometry framework, Morphic-based and [[Smalltalk]] programmed, which can be embedded and mixed with any existing Morph user interface element of the [[Squeak]] OLPC environment. It is a rewrite from scratch of Dr. Geo 1.1. However Dr. Geo II is capable to read and write to the Dr. Geo 1.1 XML file format. The examples included in the XO bundle are xml file.

* See [http://squeak.ofset.org/drgeo/clip-drgeo-esug2008.ogg this presentation video clip] demonstrating some Dr. Geo II features.

*Read this [http://blog.ofset.org/public/drgeo/drgeo-EsugAwards2008.pdf gentle overview] prepared for the ESUG2008 Technological Innovation Awards.

* As the confusion between interactive geometry and vector drawing is very common, Hilaire has produced screencasts demonstrating the use of the framework and its integration in the Morph UI (see below).

* To see more discussion on Dr. Geo II, consult the [http://blog.ofset.org/hilaire/index.php?tag/drgeo Hilaire's blog on the topic].

==How to use DrGeoII? (video screencast)==
Hilaire has prepared more than 50 video screencasts about DrGeoII. These videos are encoded in the DVD PAL resolution on the free Ogg/Theora format, so it is perfectly viewable with the XO laptops. The screencasts demonstrate:

== Installing Dr. Geo II in a XO-1 ==
To install [[DrGeo]]II, you just need to install from Browse the XO file from [https://gforge.inria.fr/frs/download.php/12155/DrGeoII-8.09.xo] or [https://gforge.inria.fr/frs/download.php/12154/DrGeoII-fast-8.09.xo](experimentall with fast loading).
The bundle comes with a few examples ready to load (one-click-load)

===What to do if it fails to install from Browse?===
In the transition to the latest XO software release, some people have had trouble downloading and installing the Dr. Geo II bundle. If installation through Browse activity fails, try the following steps:

From the Terminal activity, remove any previous Dr. Geo II bundle:
rm -rf /home/olpc/Activities/DrGeoII.activity

Restart Sugar by pressing simultaneously Ctrl+Alt+Erase so Sugar takes notice of the removal. Then from the terminal activity do:
wget https://gforge.inria.fr/frs/download.php/12154/DrGeoII-fast-8.09.xo
sugar-install-bundle DrGeoII-fast.xo
It will install the bundle in /home/olpc/Activities, if /home/olpc/Activities does not exist and Sugar complains about that, you can create it first:
mkdir /home/olpc/Activities

Eventually, if a previous version of Dr. Geo II is installed, you have to remove it:
rm -rf ~/Activities/DrGeoII.activity
Then press the keys Ctrl+Alt+Del to restart the GUI, you can then install the new bundle.

==Installing Dr. Geo II on Linux/Mac/Windows==
Dr. Geo II is not limited to the XO laptop for kid. You can use it on standard workstation and laptop. The author provides an universal one click archive running universally for Linux(i386), Mac(i386) and Windows.

To get started, download the [https://gforge.inria.fr/frs/download.php/12131/drgeo-oneclick-8.09.zip One-click distribution of Dr. Geo] and uncompress it:

*Linux users run (executre) the script <code>drgeo.sh</code>
*Windows users run the <code>drgeo.exe</code> program
*Mac OSX users drag and drop the <code>drgeo.app</code> in the Application directory

==Installing from the sources==
You want to install DrGeo in your own image, it works with SqueakLand, Squeak 3.9, 3.10, Etoys, Pharo images.
#Go to http://www.squeaksource.com/DrGeoII.html and follow the "latest" link to download the latest version (DrGeoII-HilaireFernandes.133.mcz as of this writing)
#In your Squeak image, click in the empty space, choose "open", then "file list", then navigate the directory tree on the top left panel, then select DrGeoII-*.mcz in the top right panel (not in the bottom panel). Finally click on the "load" button.
# From the "tools" tab, drag a "workspace" into the empty space. Or click in the empty space, choose "open", then "workspace".
# In the workspace, type: DrGeo new. (Make sure not to omit the period), select the entire piece of code, and press alt-d. Then a DrGeo II window appears. For a smaller DrGeo canvas without flaps, you can executre the code: DrGeo sample openInWorld
# Click in the empty space, and select "save and quit". This saves a snapshot of your squeak environment. Next time you enter squeak, all windows will appear at their present locations.

Thanks to Chao-Kuei Hung for his indications, http://people.ofset.org/~ckhung/b/dg2/prepare.en.php

Take a look to the screencasts, there are indications how to start DrGeo, and of course how to use it!


==Helping the Dr. Geo II project==

===Reporting bugs===
Dr. Geo II is a long term project developed with little resources, I can not allocate full time slot to its development and improvement. Bugs may only be fixed months after there were reported.

Therefore it is very important to report bugs properly and at the '''right place'''. The best place to report a bug is the [https://gna.org/bugs/?func=additem&group=istoa Dr. Geo II bugs tracker].
If you fell you can't report on the bugs tracker you can report it [http://wiki.laptop.org/go/DrGeo#How_to_contact_the_authors.3F by email to the author]. He will open a ticket on the bugs tracker for you.

=== Localisation ===
DrGeoII is internationalized (it requires joyride>=1620 for localisation to work).
To provide more translation, download the DrGeoII.pot file at the [http://svn.gna.org/viewcvs/istoa/trunk/artefacts/drgeo/po/ DrGeoII forge], copy it as xx.po (with xx your locale), translate and send it to hilaire [AT] ofset.org.

===Tell us your experience with Dr. Geo II===
Feel free to add your reference there

==Future plan==

===Parts to be written===
DrGeoII is now now more or less feature complete. It is about improving the quality of the existing features and tracking bugs.

===Parts to improve===
* improve the load time, the load time is now unacceptable for the user and make [[DrGeo]] unadapted for the OLPC.
* define a journal type entry to save/load.
* improve the user interface, particularly the access to the construction tools.
* improve the locus sampling, it is by now suboptimal.

===Misc===
In the early day of DrGeoII development, I implemented shape recognition. It was very basic and the user could draw circle by handwriting, move/zoom in the whole geometric sketch with specific gestures. I would like to go further.

Other suggestions for improvements, see [https://gna.org/bugs/index.php?go_report=Appliquer&group=istoa&func=browse&set=custom&msort=0&report_id=100&advsrch=0&status_id=1&resolution_id=0&assigned_to=0&category_id=101&bug_group_id=0&history_search=0&history_field=0&history_event=modified&history_date_dayfd=2&history_date_monthfd=2&history_date_yearfd=2008&chunksz=50&spamscore=5&boxoptionwanted=1#options the DrGeo tracker].

Dr. Geo is a winning award interactive geometry software for Linux, XO laptop, Windows and Mac OS X. Dr. Geo allows one to create geometric figure plus the interactive manipulation of such figure in respect with their geometric constraints. It is usable in teaching situation with students from primary or secondary level.

It is simple and effective with some unique features as scripting and Smalltalk programming.
