The Graphics Pipeline is a series of steps that a computer follows to create images from 3D models. It starts with the Vertex Processing, where the positions of points in 3D space are transformed into 2D coordinates. Next, the Rasterization stage converts these coordinates into pixels on the screen, determining which pixels will represent the shapes. After rasterization, the pipeline moves to Fragment Processing, where colors and textures are applied to the pixels. Finally, the Output Merger combines all the pixel data to produce the final image that you see on your display. This process allows for realistic graphics in video games and simulations.
