A dynamic geometry environment controlled by the dependency maintenance in EDEN.
Users can create shapes with primitives such as lines, circles and rectangles and create simple transformations of those shapes such as translate, rotate, scale and reflect. Tools for measuring angles and lengths of lines are also provided. The model took 8 weeks to write as the practical part of my MSC dissertation.
It was inspired by trying to create a piece of educational software using EM tools. It shows a good use of dependency since all the manipulations of the shapes are handled automatically by the EDEN definition maintainer.
