 An arc is defined by its support circle parameters, that is: the center position, and the radius. And the arc itself is then defined by the angle it starts from, and the angle it stops at. These are the 4 parameters we have to provide to our drawing. We'll also provide the color value so we can draw the arc in different colors if we wish.
 
-Basically, drawing a shape on screen requires it to be decomposed into a certain number of points linked one to the following one. As you can imagine, the more points your shape is made of, the smoother it will appear, but the heavier it will be in terms of processing cost. In general, if your shape is huge (or in 3D, close to the camera), it will require more points to be drawn without showing angular-looking. On the contrary, if you shape is small (or in 3D, far from the camera), you may reduce its number of points to save processing costs. This is called *Level of Detail (LoD)*. In our example, we will simply use a fixed number of points, no matter the radius.
