rasterization

Rasterization is the process of converting digital images or 3D models into a grid of tiny colored squares called pixels. When rendering a scene, the computer determines which pixels on the screen correspond to objects and fills them with appropriate colors, textures, and shading. Essentially, it's how a computer takes the complex data of a 3D scene or image and turns it into a 2D picture that we see on screens. Rasterization is a key step in creating realistic graphics in video games, movies, and other digital visuals.
