I refactored all the geometry module to eliminate redundancy and to introduce new classes for advanced functionality. I re-designed my shape 2D model, for being lighter and more compatible with current standards. For example, now it's possible to create a 2D path which is compatible with SVG format. I implemented a simple parser of SVG path, so it's possible to pass directly the string to the path 2D object, then it will be converted to custom format.
In the picture above you can see an SVG path rendered with my 2D engine and Cairo libraries. I added also 2D geometric primitives, such as circles, ellipses, arcs, rounded rectangles and splines. These elements are now also part of the 2D engine, so they are automatically converted and drawn by the graphics device. I added also two component to the geometry module, which are ShapeGenerator and CollisionDetector. ShapeGenerator is a component to generate 2D shapes from few arguments and the operation between other shapes. It will be used to convert 2D paths to bezier curves, to lines or polygons, or to generate complex shapes from a math model. The CollisionDetector component will be used for collision detection between simple shapes, like points, lines, rectangles, circles and polygons. The next step is to extend these modules for the 3D world, implementing 3D geometries, collision detection and generation for lathe and extrusion objects.
