Reaction: MARCHING CUBES - A HIGH RESOLUTION 3D SURFACE CONSTRUCTION ALGORITHM

In this paper a new, high-resolution 3D surface construction algorithm has been introduced that produces models with much detail. The proposed algorithm, marching cubes, creates a polygonal representation of constant density surfaces from a 3D array of data.

The importance of the algorithm has been very well validated by the authors. They have first described the information flow for 3D medical applications, related work and then the drawbacks of that work. After this they have explained the efficiency and functional enhancements, supported by case studies using three different medical imaging techniques to illustrate the new algorithm's capabilities.

Authors have provided ample number of diagrams to explain marching cubes algorithm. Figure 8. Bone Surface, Figure 9. Soft Tissue Surface, Figure 10. Soft Tissue, Top View and the likewise are not clear enough. Since the paper is old enough it doesn't provide the latest development in the field and hence a little out of date. I am not really sure if reading this paper would benefit anyone other than providing historical information in the field of 3D modelling. But considering that the paper is very old, its amazing that such an advanced algorithm was implemented at that time.
