Rasterization in graphics refers to the process of converting vector graphics or mathematical descriptions of shapes and objects into a raster or pixel-based image.

This process involves breaking down the geometric shapes and objects into individual pixels or dots on a grid, which can then be displayed on a screen or printed on a physical medium. Rasterization plays a crucial role in computer graphics, as it allows for the rendering of complex shapes and images with realistic detail and color.

This process is essential for creating visually appealing graphics in video games, computer-aided design (CAD) software, and other applications that require high-quality visuals. During rasterization, the computer calculates the color and intensity of each pixel based on the properties of the object being rendered, such as its shape, texture, lighting, and shading.

This information is then used to fill in the pixels on the screen or printout, creating a realistic representation of the original object. One of the key advantages of rasterization is its efficiency and speed, making it ideal for real-time applications such as video games and interactive simulations.

By converting vector graphics into raster images, computers can quickly generate and display complex scenes with smooth motion and realistic lighting effects. Overall, rasterization is a fundamental process in computer graphics that enables the creation of visually stunning images and animations.

By converting mathematical descriptions of shapes and objects into pixel-based images, rasterization allows for the realistic rendering of complex scenes and visuals in a wide range of applications.
