But, while workers have little use for the added torque, these cards are standard equipment on many new desktops these days. (An F-16 is faster than a Honda Accord--but is it really what you need for your daily commute?) While you may not have much need for a 3D card at work, your home PC could sure use one, especially if youngsters are on the prowl.
And some professionals do need the speed that 3D cards produce--and then some. Content creators (those doing modeling, animation, and CAD/CAM) also depend on fast 3D, but require higher-end-and much more expensive-accelerators.
Enter the Third Dimension
Both two- and three-dimensional graphics involve turning numbers into pictures. Just as a surveyor uses triangulation to calculate heights, angles, and distances, a graphics processor uses geometry to construct, or render, a scene from numerical data. Triangles are assembled into complex polygons, resulting in a wireframe representation of an object. Lighting and color information are then combined to fill in the wireframe model.
Unlike simple GIF animations, 3D graphics involve a constantly shifting perspective as you move about in virtual space. Real-time rendering of newperspe...
