New in 1.1.0, 27/07/2005
- Free point on a curve can be animated automatically at 4 different speeds. To use it, just use the Animation top bar menu and then select a free point on the figure.
- Shortcuts fixes.
- Adrian Ulises Soto did cleaning in the TeXmacs plugin. It also now possible to write DrGeo Scheme figure, then ask to DrGeo to evaluate it. At least the TeXmacs plug-in starts to be useful.
- From TeXmacs it is now possible to use the DrGeo menu to insert DrGeo scheme commands in the session. It is really sweet. Thanks to Adrian Ulises Soto which implement this feature.
- New and updated locales: Basque, Canadian English, Catalan, Czech, French, German, Hungarian, Kinyarwanda, Nepali, Norwegian, Spanish.
- New scheme figure examples from Mohamed Choubane and Adrian Soto Ulises. It is the Koch shape, beware it is intensively recursive and a tiling example. Visit the folder /usr/share/drgeo/examples/scheme.

The documentation is available in different formats and languages:
- Dutch: [ HTML | PDF ]
- English: [ HTML | PDF ]
- French: [ HTML | PDF ]
- Italian: [ HTML | PDF ]

Important note: The English version is completely out of date comparing to other translation in European languages. We are still looking for a native English speaking volunteer to update it. Foreigner language skill is also necessary to translate it from Dutch, French, Italian or Spanish.

 Dr. Geo in chinese, it is so sweet. It is even nicer with this wonderfull fractal composed of several thousands objects. It comes from Mohamed Choubane. |
 It is so confortable to use the macro-constructions from the main menu. In top of the macro name, its description is also displayed as a tooltips. |
 The Euler Line, the interface is in Polish. |
 A Locus representing a parabolic curve. Note at the left the construction tree of the figure. |
 Another locus representing an ellipsis. Note: two loci are used to represent the complete ellipsis. |
 Figure showing how Thales Theorem and the trigonometry are related. This example use the advanced DrGeo Guile Script, the dialog shows one of the used script. |
 Using DrGeo to play with the axial symmetry. Here the Mercedes logo, the student can move the axe and find the axe of symmetry of this logo. Note also the dialog to hide/show the available tools within the figure. |
 Here another example illustrating the locus and script features. It is used to show the cosine curve with a moving point on it. To the moving point is attached the tangent to the curve. The curve is computed with the locus and script tools, the tangent with the script one. |
 Dr. Geo used under a German environment, it shows the printing area feature. German is one of the very well supported translation. |
 Dr. Geo used under an Italian environment, it shows the Archimede's saltcellar. Italian is one of the very well supported translation with the documentation translated as well. |
 Dr. Geo exposing the Script and Macro-Construction features used together. In this example, these features are used to extend Dr. Geo with a signed distance functionality. |
 Exploring new way to create interactive figure with Dr. Geo. Here we use the Dr.Geo Scheme Figure (DSF) to create functionally geometric figure: the figure is defined in the Scheme programming language, then the code is evaluated within Dr.Geo. We can configure the SCITE text editor to edit the code and to evaluate it directly with Dr. Geo |
 Another example where script are intelligently used to illustrate a problem. |
 Who say we can't use Dr. Geo in Chinese to expose some aspect of Physics Science? Not Chao-Kuei Hung who contribute this screenshot. |
