Application
===========
Dr. Geo 0.9.10
Description
===========
Dr. Geo 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 useable with students from primary or secondary level.
Enhancements & Fixes
====================
- New updated French, Italian, Spanish user manual.
- New spanish synonyms to create Dr. Geo Scheme Figure with spanish
words.
- Fix in the macro system. A bug has appeared with the improvement in
release
0.9.8. The cascading effect was that Dr. Geo hung when saving oldest style
macro. It did not show up with freshly created macro.
- Implement a simple and dirty intersection tool between line and locus,
beware
it may not work as you expect. I will eventually consider extending it if
there
are enought demand.
- Small patch from Sebastian Kapfer to fix an infinit loop when parsing
line
command parameters.
- Implement two new methods getUnit and getNormal in the script API. These
are
used to fetch a unit and a normal vector to a direction. Vectors' norm are
equal
to 1.
- When exporting to PostScript adjust the scale so that 1 unit = 1 cm.
- Remove a bug which appear when a user edit a free value.
- When an object is created from a DSF, the description in the side bar is
not
updated. This really speed up the DSF evaluation.
- Interesting contributed example files from Rhydwen Volsik and Sebastian
Kapfer. See in /usr/share/drgeo/examples/[figures,scheme]
- More examples from Chao-Kuei Hung, these examples show some smart use of
DrGeo
for Physcis Teachers.
- New and updated translations: Czech, Danish, Dutch, French, German,
Italian,
Norvegian, Polish, Serbian, Swedish.
- Rhydwen Volsik contributed an interesting figure with a lot of loci and
scripts, this figure gave me the opportunity to optimise a bit the locus
sampling.
- Continue extending the DSF API. The following Scheme functions were
defined:
* make-circleLength
* make-lineSlope
* make-arcLength
* make-orientedAngle
