Swing Program class SwingTemplateJPanel extends JPanel else if (direction = imgFrames. 2D (of the Java 2D API) greatly extends the functions and capabilities of the Graphics class. It supports mainly straight-line segments. The class is, however, limited in its functions and capabilities. It is important to take note that the graphics co-ordinates system is 'inverted', as illustrated. Display clipping area ( getClip(), getClipBounds(), setClip()).The Graphics class also allows you to get/set the attributes of the graphics context: Vector-graphic primitives and shapes: via drawXxx() and fillXxx() for Line, PolyLine, Oval, Rect, RoundRect, 3DRect, and Arc.It manages the graphics context (such as color, font and clip area) and provides methods for rendering of three types of graphical objects: JOAL (Java Bindings to OpenAL) for advanced sound.

JOGL (Java Bindings to OpenGL), or Java3D for 3D graphics.Transformation, collision detection and reaction algorithms.Basic knowledge on I/O, multi-threading for starting the game thread, and timing control.Graphics programming using Java 2D ( ).Event-handling, in particular mouse-event and key-event handling ( ).GUI and custom graphics programming ( javax.swing).OOP, in particular the concepts of inheritance and polymorphism for designing classes.(iii) It is a closed figure with three straight sides.Įxample 4: Write the number of sides and vertices (corners) each figure has.The pre-requisite knowledge needed to for game programming includes: Images depict objects in the environment that are close to the geometric shape of circles, triangles, rectangles. (ii) It has one pair of opposite sides parallel to each other while the other two sides are non-parallel. Description This is a set of 2D shape clipart. A 2D shape has no thickness or depth.Įxample 3: Match the 2D shape with its property. A 2D shape has two dimensions: length and width. The circle is an example of a 2D shape.Solved ExamplesĮxample 1: Which of the following are 2D shapes?Ĭircle Sphere Cylinder Pentagon Kite Rhombus Formula of 2D Shapes Difference Between 2D Shapes and 3-D ShapesĪ point is zero-dimensional, while a line is one-dimensional for we can only measure its length. Semi-Circle:Ī diameter of a circle divides the circle into two equal parts. It is the set of all those points in a plane whose distance from a fixed point remains constant. Sides are grouped into two pairs of equal sides that are adjacent to each other. It has four straight sides with one pair of opposite sides parallel to each other and the other two sides of it are non-parallel. It is a special type of quadrilateral whose all sides are equal in length. The opposite angles are of equal measure. The opposite sides of the rectangle are equal in length. The opposite sides of the rectangle are equal in length and they are parallel.

It has four sides, four vertices, and four angles each measuring 90°. It has four sides, four equal angles each measuring 90°. It has three straight sides, three angles, and three vertices. Let’s learn 2D shapes names and 2D shapes attributes and properties: Triangle: Examples of 2D Geometric ShapesĪ circle, triangle, square, rectangle, and pentagon are all examples of two-dimensional shapes. A two-dimensional (2D) shape can be defined as a flat figure or a shape that has two dimensions-length and width. Two dimensional or 2D shapes do not have any thickness.ĢD figures can be classified on the basis of the dimensions they have.
