Computer Graphics Course And Certification
What is Computer Graphics?
Computer Graphics is the art of drawing pictures and charts lines using computers achieved with the help of programming. Computer graphics are made up of a number of pixels. A Pixel is the smallest visible unit of an image displayed on the computer screen.
Computer Graphics is the technology that concerns the design and manipulation of pictures on the computer. Graphics is defined as an image or a visual representation of objects. It is all about computer programs that are capable of displaying pictures.
To display a picture of any size on a computer screen can be somewhat a difficult process. Computer graphics are used to simplify this process, various algorithms and techniques are used to generate graphics and make them display properly on computer devices.
Graphics in the computer screen are grouped into two types which are:
- Raster Graphics and
- Vector Graphics.
Raster Graphics Editor is a computer program that allows users to create and edit images as an array of pixels. Popular raster formats are JPEG, PNG, GIF and TIFF.
Vector Graphics use paths, points, lines, shapes, curves or polygons (all of which are based upon mathematical equations) for the same purpose.
Features of Computer Graphics:
There are a lot of features of computer graphics software some of them are:
- Title Bar: The title bar is the part that displays the document title usually at the top of the screen.
- Ruler: The ruler feature is used to determine the size and position of objects that you are drawing on the computer.
- Menu Bar: The menu bar is the area on the screen that contains a list of all the commands to be found within the graphic software.
- Standard Toolbar: The standard toolbar is a bar that you can remove which shows shortcut commands of the software.
- Property Bar: The property bar is a detachable bar that contains commands that are relative to the object or tool that you are currently working with.
- Color Pallete: The color palette is a dockable bar in graphic design software that contains color swatches.
- Drawing Window: The drawing window is an area outside the printable page. it creates a border around the printable page.
- Drawing Page: The drawing window is a rectangular area inside the drawing window also known as the printable area because it is the printable area of your drawing.
- Toolbox: The toolbox is a detachable bar containing tools for selecting, creating modifying and filling objects in the drawing.
- Magnifier: The magnifier is used to zoom in or out on a particular selected area of your drawing or picture.
- Eraser: The eraser as its name suggests, is used to erase areas of your drawing or picture.
- Text: The text feature is used to enter text in the picture or drawing.
- Fill With Color: Fill with color is used to fill the entire picture or a selected covered shape with color.
Benefits of Computer Graphics:
There are many benefits and advantages of computer graphics, some of them are:
- Computer graphics gives us the ability to store, create and display complex drawings easily and properly with the help of programming.
- Computer graphics allows us to use easily interactive devices to build simulations.
- It widens our knowledge about graphics in computer programs and applications.
- It helps in generating pictures or images.
- It assists in changing and moulding images into motion pictures.
- It makes computation easier and in an accurate way e.g. with the help of gridlines.
- It also helps in performing sequence of transformation and translation or scaling of objects or images.
- It is used for engineering drawing.
- It is used in business presentations
- It provides the ability of a computer system to store complex drawings and display them whenever needed.
- Computer graphics is one of the most effective and commonly used ways of communicating graphics on computing devices.
- One of the major goals of computer graphics is to create realistic images in real time.
Types of Computer Graphics:
Basically there are two types of Computer Graphics namely:
Interactive Computer Graphics:- This involves a two way communication between the computer and the user. Here the user is given some control over the image by providing him with an input device for example the video game controller of the ping pong game. This helps him to signal his request to the computer. The computer on recieving signals from the input device can modify the displayed picture appropraitely. The user can give a series of commands, each one generating a graphic response from the computer. In this way he maintain a conversation, or dialogue with the computer. Interactive Computer Graphics improves our life in a number of ways, for example, it helps to train pilots on aircrafts etc.
Non-Interactive Computer Graphics:- Non-Interactive Computer graphics is the type of graphics in which the user does not have any kind of control over the image. Image is merely the product of static stored program and will work according to the instructions given in the program linearly. The image is totally under the control of program instructions for example screen savers.
