goop

** This project is an experiment. **

Goop is an object oriented graphics library. It uses LWJGL to create the windows and draw the shapes. The advantages over plain Java2D/Swing/JavaFX are:

• It is based on decorators
• The state of every object is set by the call of the constructor
• No setters/getters
• Small classes and interfaces
• Every method is defined by an interface
  And most important: The object knows what happens to him.
  Here is an example to visualize how it will look:

new Window(
  "I am a window",
  new Area2D(
    new Pos2D(0, 0),
    new Size2D(500, 500)
  ),
  new Rect(
    new Area2D(
      new Pos2D(0, 0),
      new Size2D(500, 500)
    ),
    new Black()
  )
).show();

Or using the defaults and assuming that the size of the rectangle is equal to the size of the window:

new Window(
  "I am a window",
  new Rect(
    new Size2D(500, 500)
  )
).show();

This is how a moving rect would look like:

new Window(
  "I am a window with a moving rect",
  new Size(500, 500),
  new Rect(
    new Moving(
      new Pos2D(0, 0), // from
      new Pos2D(100, 100), // to
      10_000 // ms needed
    ),
    new Size2D(200, 200)
  )
).show();

The class Moving implements Pos and Rect takes a Pos - no getter/setter needed, because the object itself is in control.
