The Border of drawing is represented by the white rectangle. First, you will need to select a shape. If you want to create a Bezier curve, you will need to press the “new” button. The left mouse button (LMB) click will start a rectangle, or ellipse drawing. By holding the LMB, you can resize the drawing rectangle, ellipse, or move the control points for the Bezier curve. You can set effects and clear all drawings. Additionally, the camera can be 2D, or 3D. This demo supports touch input, so it is ready for mobile platforms, where it works excellent.
