Anisotropic filtering (AF), which makes images look crisper.Full scene anti-aliasing (FSAA), which smooths the edges of 3-D objects.The graphics card accomplishes this task using four main components: Without a graphics card to perform the necessary calculations, the workload would be too much for the computer to handle. For fast-paced games, the computer has to go through this process about 60 to 120 times per second. It also adds lighting, texture and color. Then, it rasterizes the image (fills in the remaining pixels). To make a 3-D image, the graphics card first creates a wire frame out of straight lines. It then sends that information to the monitor through a cable.Ĭreating an image out of binary data is a demanding process. The graphics card decides how to use the pixels on the screen to create the image. The CPU, working in conjunction with software applications, sends information about the image to the graphics card. The end result is that someone's idea becomes an actual, viewable picture.Ī graphics card works along the same principles. The art department decides how to create the image and then puts it on paper. When people in the company want a piece of artwork, they send a request to the art department. Think of a computer as a company with its own art department. We'll also examine the factors that work together to make a fast, efficient graphics card. In this article, we will look at the basic parts of a video card and what they do. A graphics card's job is complex, but its principles and components are easy to understand.
