Reaction: Marching Cubes - A High Resolution 3D Surface Construction Algorithm

Although there are technological advances in the medical field helping physicians understand the internal bone/tissue structure, it has become essential to ensure that this info is presented in a way that is more visual and easy to comprehend. This paper presents an algorithm called marching cubes that helps the above cause and generates 3D surfaces of input medical data.

The paper is an interesting read and I personally was unaware of the importance of image processing and visualization on medical data. The algorithmic approach presented in the paper is easy to comprehend. The steps of marching cubes algorithm and optimizations at each level are explained very well. The reader will need some background in computer graphics to understand some of the optimizations applied to the algorithm. There are some nice pictures which show the effect of using the algorithm. To do justice to the algorithm there should have been a comparative study with one of the algorithms mentioned in the related work.
