What is supersampling (antialiasing technique)?
Ans: Algorithmic antialiasing techniques involve “sampling” the content of each pixel at multiple locations, meaning that the color is computed at more than one location inside the area covered by the pixel. The results from these “samples” are combined to determine the final color of the pixel. These samples are essentially additional pixels, used to increase the effective resolution of the image to be displayed. If the edge of an object falls partially inside the area of a pixel, its color and the color of another object that partially fills the “area” of the pixel can both be used to calculate the final color. The result is smoother transitions from one line of pixels to another line of pixels along the edges of objects, where aliasing is most obvious. “Supersampling” is an antialiasing technique that is simply a brute force approach and is used in NVIDIA’s GeForce2 GPUs and other modern graphics processors. A graphics processor that uses supersampling renders the screen image at a
