A pixel is the smallest unit of a digital image or display, while resolution refers to the number of pixels in an image or display, usually expressed as width by height (e.g., 1920x1080).

Augmented reality (AR) is an interactive experience of a real-world environment where the objects that reside in the real world are enhanced by computer-generated perceptual information. Virtual reality (VR) is a simulated experience that can be similar to or completely different from the real world.

Computer graphics are used in various applications such as video games, simulations, virtual reality, image processing, computer-aided design (CAD), medical imaging, and scientific visualization.

<p>The DDA (Digital Differential Analyzer) algorithm is used to generate a line between two given points. It works by calculating the incremental values in the x and y directions and plotting the points based on these increments. For example, to draw a line between points (2, 3) and (8, 10), the DDA algorithm would calculate the slope and increment the x and y values accordingly to plot the line.</p> Signup and view all the answers
