Reaction: Marching cubes: A high resolution 3D surface construction algorithm

     This paper talks about marching cubes  Algorithm " A new, high-resolution 3D surface construction algorithm. Basically the algorithm has following steps

1.Read four slices
2. Scan two slices and create a cube
3. Calculate an index
4. Find the list of edges from LUT
5. Find the surface-edge intersection
6. Calculate a unit normal at each cube vertex
7. Output: the triangle vertices, vertex normals." The adaptive algorithm produces a very close approximation of the original surface.New methods that extend marching cubes algorithm will likely produce more accurate localization.
