Many computer graphics programmers are working in the area of scientific visualization. One of the most interesting and fast-growing areas in scientific visualization is volume visualization. Volume visualization systems are used to create high-quality images from scalar and vector datasets defined on multidimensional grids, usually for the purpose of gaining insight into a scientific problem. Most volume visualization techniques are based on one of about five foundation algorithms. These algorithms, and the background necessary to understand them, are described here. Pointers to more detailed descriptions, further reading, and advanced techniques are also given.
