Calques 3D

Calques 3D is a microworld designed for constructing, observing and manipulating geometrical figures in space.
It allows an intuitive and adaptable access to environment features.
Intuitive because it has to be used by students who do not have preparation.

Adaptable because it has to allow the teacher to decide, with respect to his own pedagogy, which primitives and operations will be made available to the student.
