Abstract:
In many areas of science a general visualisation problem exist, 
namely that the fundamental object is a three dimensional 
structure embedded in a rectangular volume. One example could be 
data from medical brain scanners. Normally it is qualitatively 
easy for the human to see and identify the structure from, e.g., 
images of the individual slices through the volume. It is, however, 
desirable to have automatic procedures, working in 3D, to track 
the boundary of the object and to generate a closed set of triangles 
(polygons). These closed surfaces can be used to visualise the 
object in 3D, or to perform quantitative measurements within the 
structure.
