👉 Goniaster is a type of mathematical tool used in the field of computer graphics to represent an angle. It consists of two lines, one parallel and one perpendicular to each other, which are drawn on the surface of a 2D plane or 3D object. The angles formed by these lines are then calculated using trigonometric functions such as sine, cosine, tangent, etc., to obtain the position of an object at any given time. In computer graphics, goniaster is used
