=CaRMetal is a Geogebra like free software=
'''Tharanath Achar,Govt. P U College,Belthangady''' Dear Radha Madam and those who want to know more,
Last week I installed a new software which was available in Application--> Ubuntu Software Center ---> Education --> CaRMetal. Within minutes the software installed and to my surprise it was just resembled Geogebra. It is easier than Geogebra but I don't know whether it is better than th latter. I found it very easy and I needed some geometric figures to set a question paper for my 10th Boys. I exported it as .SVG file. It was very smart, I could scale it up or down in a Writer file when inserted in to it as picture. The file extension of the CaRMetal file is .zir.
Later I found that the software was designed In Germany by Eric Hakenholz and is in use since 1989. [ Quite old]
Please follow the Wikipedia @ http://en.wikipedia.org/wiki/CaRMetal'''
Bindu Thirumalai, IT for Change''' Dear Tharanath and Radha and All Teachers
First of all I am glad you are exploring more tools. Two is always better than one. This is the beauty of Public Software, we always have more variety to choose from. And now that you know GeoGebra, you will easily be able to try and experiment with CaRMetal. Most mathematics tools will follow similar processes.
Where you can use CaRMetal.
1. For pure Geometry constructions
2. For 3D visuals which Geogebra does not have as yet
3. Animation is there, it is not as simple as sliders , we can explore it a little more
Where to use GeoGebra
1. When we combine Algebra and Geometry - this feature is not as good in CaRMetal.
2. When we combine statistics (spreadsheets) , with algebra, charts - Geometry - this feature is not there in CaRMetal.
