Once you know how to show a dot on the screen, other shapes are easy. (If you don’t, review chapter 1.) Most mathematical shapes can be drawn on the screen. The classes to do that are in the green folder Esenthel Engine ⇒ Math ⇒ Shapes.
Not all available shapes are intended for display in 2D. Some classes, like Ball and Tube, are intended for 3D development. For now, we will focus on 2D shapes like Circle, Edge (line), Quad, Rectangle and Triangle.
