Algorithm of Marching Cubes

There are two different visual algorithms for volume data in three-dimensional space. The first class is that to geometric primitive such as surface and in-plane from three-dimensional space, and then to realize surface rendering with traditional computer graphics technology. The most common geometric primitive is in-plane, when we need to extract iso-surface from three-dimensional space is this case. There are many methods to construct iso-surface, and Marching Cubes is most representative. It came up with W.E Loren son, H.E and Cline in 1987. Because this principle of method is very easy and it's easy to realize, so it is widely used at present.
