Euclide 0.3.2

Euclide is a dynamic geometry creation application written in Java.
Euclide allows creation of geometric shapes and transforms (rotation, symmetry...), which depend each other. Moving a shape will also move shapes dependent on it.
In Euclide you start by placing some free points, then you create objects using these points: lines, circles, line segment, circle arcs... each new figure can in turn be used to compose new shapes.
Main features:
Creation of shapes
Various shapes can be created from selecting other geometrical objects (shapes, measures, transforms), or by specifying manually value for position, radius... When a shape need a new point, the user clic on a point of the figure, or on the location of a new free point, which will be created in the same time as the new shape. Here is a list of available shapes:
Points:
- Free point
- Intersection point of a curve and a line
- Point on a curve (closest point to another point)
- Point on a curve (with a defined geodesic position)
- Centroid of several point
- Transformed point (by any planar transform)
Linear objects:
- Line segments (from 2 points)
- Straight lines: From 2 points, Parallel to a line through a point, Orthogonal to a line through a point, Median of 2 points, Radical axis of 2 circle
- Line arcs (from 2 points, bisectors, reflexion of a ray on a curve...)
- Polyline (from a series of points)
Circles
- From center and a point belonging to the circle
- From center and radius (given as distance measure)
- From 2 diameter points
- From 3 points on the circle
Circle Arcs
- Circle arc from 3 points
- Circle arc from 3 points, with specific orientation
Curves
- Bezier curve from 4 points
- Composition of several curves
Measures on shapes
Distance/length measure
- Closest distance of a point to a shape
- Radius of a circle
Signed distance measure
Angle measure
- Signed angle between 3 points
- Horizontal angle of a line or a linear object
- Horizontal angle of 2 points
Counting measures
Transforms
- Translation by the vector joining 2 points
- Rotation around a point with a given angle
- Line symetry
- Point symetry
- Circle inversion
System requirements:
- Java Runtime Environment

Enhancements:
- Layers can be deleted, and order changed
- New documents can be created
- Shapes can now be deleted, with all objects depending on them
- Added a text over mouse cursor to help identify current selected shape
- It is possible to create composition of affine transforms
