Hi Phil and Hilaire,
I have already developed

Oggetto: Re: [Pharo-project] Dr.
Geo for acadamy
Hi,
Doing nice formulas in Pharo would be of interest to me. And
manipulating them even more (I am busy with that now).
As for Geogebra as competition, these guys are now doing a ton of 3D
(we use GG here with my wife, a maths teacher) and their DSL is pretty useful
once mastered. I find myself constructing a lot of things from the little
"command prompt" of theirs. That would be an interesting addition to
DrGeo (and why not being GG-compatible on the commands).
I know I can get a browser and all, but that's not cutting it the same
way.
DrGeo is Java-free, so where can we use it where Java is not fine?
I'll look at what I can propose for engineers to work on. I'd add that
a solver for constraints would be nice to have (like Simplex).
Also, a good thing to add to DrGeo is a window with a list of entities
with their name and possibility to rename/change attributes from there. Once
the things get complex, this is a godsend in GeoGebra...

Hello,
Thinking aloud. May be I already discussed the following ideas with some of
you.
Dr. Geo is now mature enough to learn from it and to propose it as a tool
students in computer science and/or mathematics can use for final projects or
study projects.
The idea is to propose student programming projects around Dr. Geo. A list of
projects should be drafted and designed to be appropriate for students. I am
not really sure about the level of difficulties, the duration such project
could take, but listing ideas could be a good start. Moreover, I don't know if
the idea elaborated in this document make any sense, so your feedback on that
point would be greatly appreciated as well. Another requirement could be to
list why students will benefit working in a project around Dr. Geo, to be done
later if the idea take off.
Regarding Dr. Geo project itself the benefice is more to gain in visibility and
not in contributions coming from students work, indeed sudents will more likely
maintain the project only for the duration of their studies. But more
visibility on Dr. Geo can mean more long term contributors, hopefully from the
academic sector. Dr. Geo need it to scale up and to compete with other alike
project like GeoGebra where the contributors are numerous. If not, Dr. Geo will
remain an epiphenomena and the great concept behind Dr. Geo, modify me from
myself, will be lost.
Regarding the project ideas, I see two categories: projects of interest for Dr.
Geo and other Smalltalk ones and projects tightly related to Dr. Geo core.
1. Projects of interest for Dr. Geo and other Smallktalk software:
- framework to render latex formula
- mini-worksheet package to embed in an application
- supplementary Polymorph widgets
- mini algebraic system for symbolic manipulation of mathematic expressions
- proof system, prolog or purely Smalltalk based
2. Projects tightly tied to Dr. Geo:
- SVG, EPS exporters
- new UI paradigm to build interactive sketch
- porting to other system, closely related to Virtual Machinery
- More constructions tools, it is a very good teachable as it dives you in an
application with a lot of design patterns in action. See following document
https://blueprints.launchpad.net/drgeo/+spec/todo-to-implement-new-tool
There are more ideas.
If you think about any person involved in the academic sector, please forward,
this is why I wrote the document in Frenglish after all.
Thanks
Hilaire Fernandes
