Explaining the Interactive and Non-interactive Computer Graphics



workplace

Computer graphics is the art of drawing pictures, lines, charts, etc using computers with the assistance of programming. special effects are formed of a variety of pixels. Basically, there are two forms of lighting tricks namely.

Interactive lighting tricks: Interactive Computer Graphics involves two-way communication between computer and user. Here the observer is given some control over the image by providing him with a device for instance the game controller of the ping pong game.

The computer on receiving signals from the data input device can modify the displayed picture appropriately. To the user, it appears that the image is changing instantaneously in response to his commands. He can provide a series of commands, each generating a graphical response from the computer. During this way, he maintains a conversation, or dialogue, with the computer.

Interactive camera work affects our lives in a very number of indirect ways. as an example, it helps to coach the pilots of our airplanes. we are able to create a trainer that will help the pilots to induce trained not during a real aircraft but on the grounds at the control of the simulator. The simulator may be a mock-up of an aircraft landing deck, containing all the same old controls and surrounded by screens on which we have the projected computer-generated views of the terrain visible on take-off and landing. Flight simulators have many advantages over real aircraft for training purposes, including fuel savings, safety, and therefore the ability to familiarize the trainee with an oversized number of the world’s airports.

Non-Interactive Computer Graphics: In non-interactive camera work otherwise referred to as passive camera work. It’s the pc graphics within which the user doesn’t have quite a control over the image. Image is simply the merchandise of a static stored program and can work in keeping with the instructions given within the program linearly.
