A comparison of fundamental methods for iso surface extraction

Patera J., Skala V.

Machine Graphics and Vision

2004

Vol. 13, No. 4

329-343

This paper compares four fundamental methods for iso surface extraction based on cell decomposition to tetrahedra. The methods are compared both on mathematically generated data sets as well as on real data sets. The comparison using mathematical data is made from different points of view such, as area approximation, or volume approximation. On the other hand, the Hausdorff distance and the root mean square are used to compare methods on real data sets. The presented comparison can be of help when deciding which of the tested methods to choose, as well as when we need to compare a newly developed method with other existing approaches.

Laplacian mesh smoothing for tetrahedra based volume visualization

Stęgierski R., Mikołajczak P.

Journal of Medical Informatics & Technologies

2002

Vol. 4

MT11--18

In this paper an improved method for three-dimensional (3-D) surface reconstruction from computed tomography slices is presented. Marching cubes (MC) is a popular method for extracting iso-surfaces from discrete (3-D) data. We implemented a simplification of marching cubes, commonly known as marching tetrahedrons (MT).
