Creating pictures with the help of computer is called computer graphics. In this two- or three-dimensional pictures are created. In this, many software techniques are use to create, modify, and store pictures. With the help of Computer Graphics, we can display any size image on the computer screen. Future of Graphics are present in computers using many algorithms and techniques. Nowadays computer graphics are use everywhere such as in user interface, T.V. In, in motion pictures, and in mobile games etc. Computer graphics is made up of many pixels. A pixel is the smallest unit of graphics visible on a computer screen.
Types of Computer Graphics
There are two types of computer graphics which are as follows-
- Interactive Computer Graphics
- Non-Interactive Computer Graphics
Interactive Computer Graphics
Interactive computer graphics are those graphics in which the user has control over the picture, that is, the user can make any kind of change in the image.
In this, two-way communication takes place between the user and the computer. Nowadays all work stations and computer systems use interactive computer graphics.
Example of: –
- Drawing image on touch screen
- graphics in video games
- animation in a movie
In interactive computer graphics, the user requests the computer through the input device and the computer changes the picture or image according to the request sent by the input device. The user can give any number of commands through the input device and the computer generates pictures according to those commands.
Non-Interactive Computer Graphics
Non interactive computer graphics are also called passive future of computer graphics. Passive computer graphics are those graphics in which the user does not have any kind of control over the picture or image visible on the computer, that is, in this the user cannot interact with the pictures and there is no change of any kind in the pictures. can do. The user can only view the image on the computer and cannot make any changes in it. In this there is only one way communication between the user and the computer.
Applications of computer graphics
It is use at many places which are given below: –
In Computer Art –
By using computer graphics, we can create wonderful art. Through this we can create cartoon, logo design and painting.
In Education –
Using computer-generated models in teaching is very beneficial. With this it becomes very easy to explain the concept of any subject. With the help of graphics, students learn easily and their interest in the subject increases.
In Video Games –
Video game is an electronic game in which some pictures are visible to the user on the screen with which he interacts. All these video games are make with the help of graphics.
In Architecture –
It is use by architects to create drawings of buildings.
In Entertainment –
Nowadays it is use the most in the field of entertainment such as in making movies, television shows, motion pictures and music videos etc.
In training –
It is used in training so that employees can be train well in less time. For this, training modules are create with the help of computer graphics.
In Machine Drawing –
It is use to design many parts of the machine.
In graphical user interface –
Computer graphics are use to create user interfaces. In this, pictures, icons, pop-up menus etc. are made.
Advantages of computer graphics
Its benefits are as follows: –
- With this we get high quality images on the computer.
- It provides tools with which we can create real world objects. Through these tools we can create 2D, 3D and even 4D images.
- Computer graphics has the ability to show moving pictures. Therefore, through this we can create animation.
- Through computer graphics, the user can control the speed of the animation and also the view of a part of the image.
- It also has the facility of update dynamics through which the shape, color and other properties of the picture can be change.
- In this the cost of designing an image also reduces.
Disadvantages of computer graphics
Its disadvantages are as follows: –
- Its biggest disadvantage is that creating computer graphics is not easy.
- Training is require before using it. It requires skills.
- Computer based graphics software has to be update continuously which costs a lot of money.
- It takes a lot of time and effort to design images or pictures.
Computer graphics is make up of two words, if these two words are understand then you will be introduce to future of computer graphics. Computer means a machine or device that performs processing, calculations and operations as per the instructions of software or hardware programs. It takes data as input and processes it and shows us the output. Graphics means a type of artwork, design or visual image, which is prepare on a canvas, paper, wall, sign board or computer monitor. These are make to provide information or entertain.
