Dr. Geo II is a complete rewrite of Dr. Geo 1.1 GTK for the Squeak/Smalltalk environment As now, loading Dr. Geo II is slow because it is shipped in source code form and compiled at load time by the OLPC Squeak/Smalltalk. In future pre-compiled version will be provided for faster load time
(From the Dr. Geo 1.1 website)
Dr. Geo 1.1 is a GTK interactive geometry software. It 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 integrates advanced features as an integrated Scheme programming language to define scripts within a figure. The language is also used to define functionally interactive figure.
Dr. Geo is a software part of the GNU project. This means it is a free software (as free speech) and you have access to the source code under the GPL license. You can modify and distribute it as long as the same distribution license (GPL) is used. To learn more about this license and the Free Software Foundation, visit the GNU project web site or read the file COPYING in the distribution.
At the Dr. Geo gallery you will find several examples with Dr. Geo. Do not hesitate to reference your examples there.
How to install DrGeoII
To install DrGeoII, you just need to install from Browse the XO file from [1]. The bundle comes with a few examples ready to load (one-click-load)
DrGeoII 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.
As the confusion between interactive geometry and vector drawing is very common, Hilaire has produced a few video recording exposing the installation and the use of the framework. Moreover the videos show how the Morph UI gives freedom to mix in a constructive manner various unrelated Morph components (user interface construction, user interface scripting between different unrelated components).

Localisation
DrGeoII is internationalised (it requires joyride>=1620 for localisation to work). To provide more translation, download the DrGeoII.pot file at the DrGeoII forge, copy it as xx.po (with xx your locale), translate and send it to hilaire [AT] ofset.org.
