How real world object is converted to image?
Objects are physical entities that represent actual objects. Objects can be natural, such as flowers, clouds, mountains, and trees, or manufactured, such as a car, cell phone, book, ball, and so on. A three-dimensional coordinate system is used to represent objects. Computer graphics is concerned with the representation of real-world objects on a computer screen. An image is a representation of real-world items on a digital display device. Objects in the real world are continuous, with a smooth boundary. They are discretized when mapped on a monitor screen and frequently have zigzag boundaries due to the grid layout of the monitor screen.Image is formally a two-dimensional array of pixels. A pixel is an image’s smallest addressable unit. Image is defined mathematically as a function of its spatial coordinates (x, y). Where (x, y) is the pixel position in the image and function f(x, y) is the intensity or color at that place. The diagram demonstrates how continuous shapes are changed to discrete entities while being turned into a digital image or mapped on a monitor screen.
