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

In this paper, the author proposes a new algorithm for representing 3D data that is commonly used in medical applications. The first step in most of the 3D data representation algorithms is to gather the 3D data . Subsequent steps involve filtering the data, creating a surface model and displaying the surface. Most of the algorithms do not make use of all information contained in the 3D data. Hence a new algorithm based on the divide and conquer technique called 'Marching Cubes' is proposed. According to the author,the success of the algorithm is dependent on the speed and capacity of CAD hardware.

The author assumes that the readers have the prerequisites in 3D graphics and hence no background information is provided. I found it very hard to understand some of the methods followed for generating 3D surfaces. The information presented in the second half of the paper was too detailed and requires additional reading to be able to understand and evaluate the algorithm. Also, the paper is very old and it is possible that there have been several modifications to this algorithm.
