Hi v-geom is written using E-toys with an intuitive interface.

All objects are in a figure on a playfield checked as parts bin and available by clicking on them. Parameters are given using the player's type variable widgets attached to the objects.

Help balloon are indicating the kind of object needed.

the color of the widget is: yellow for points. black for lines magenta for circles

This project is modifying the polygonMorph class and adds two new categories: morphing (used for animations) vertices which enable working with the handles in E-toys scripts.

The widgets used in the interface of V-geom is the start point for v-toys.

Hello,

I have redesigned the Dr. GeoII[1] user interface to make it looks like a Morph component. It is more in the Squeak Morph constructivist philosophy approach (see screenshot).

Now you can create an interactive geometry canvas (a PasteUpMorph exactly) from the PartBins ([Alt]+O). From the halo menu or the canvas menu you access two submenus, one to select a construction tool, the other one to get buttons you can plug any where you want.

These changes mean you can take a DrGeo canvas and plug it in a BookMorph page, then take some construction buttons you want the kids to use and plug them in the page book as well. Well the usual stuff you expect with Squeak.

Sorry the menu are still only in French, but you know that English and French vocabulary are very close, don't you?

Fetch the latest source from http://www.squeaksource.com/DrGeoII.html. It should work with 3.8, 3.9 and SqueakLand.

It will be great if someone could produce a screencast.

Really designing stuff with Squeak is of great pleasure!

Looks very interesting. To bad I don't read any french, I have a hard time understanding what to do with the different objects. Here is a link to another project I have been using a little : http://mathsnet.net/campus/construction/

You could publish the project on Squeak Map for even easier access Karl

"In the OLPC image its even simpler to make a project like this because there is already a polygon category so you drop a ellipse and a polygon in the world and make a script like the attached pict."

Hi, I just discover this while searching solution for the question pen trail as object in the discussion list. All this job was done about 4 or 5 years ago using squeak 3.6.

I have worked on connecting interactive geometry and expert system in squeak prolog. The expert system (forward chaining)was doing deductions about the figure using rules about geometry.

But squeak prolog is no more working for squeak version higher then 3.6

I have tried to use Scheme and Schelog , but too slow to be useful.

What I did now is an interface to get affirmations in a text and to paste this text in other programs for instance swiprolog which is very fast.

I have an interface doing the same thing for Squeak DrGeo too.

You can see a screen shot of this and comment (in French) on the wiki of the French Squeak community:

http://community.ofset.org/wiki/G%C3%A9om%C3%A9trie_et_syst%C3%A8me_expert

This is a project on which I'm working now.

I'll do a new version of v-geom for OLPC using olpc's tiles so that OLPC image will not be changed.

The change set used was adding two new categories one about vertices no more useful and one for morphing,which enable to keep the successive positions of the vertices in an array and to generate intermediate positions (Morphing) for creating animation of frames.

The attached change set will just add the Morphing category to polygons.

See balloon help of tiles for documentation.

Regards

In the OLPC image its even simpler to make a project like this because there is already a polygon category so you drop a ellipse and a polygon in the world and make a script like the attached pict. Karl
