ABSTRACT

The previous chapters presented algorithms and data structures for building an isosurface for a given isovalue. In this chapter, we discuss algorithms and techniques for choosing this isovalue.

Choice of isovalue is application dependent. Different imaging devices, different materials, and different areas of interest dictate different choices for the isovalue. Nevertheless, there are some generic algorithms and techniques that can assist in finding the isovalue that determines the desired isosurface.
