In the commonly used fast watershed mesh segmentation method [15], a height function is defined based on the curvature of triangular facet to extract the boundary of neighboring mesh models.
As shown in Figure 2, three noncollinear points [L.sub.0], [M.sub.0], and [N.sub.0] compose a triangular facet (denoted by [DELTA][L.sub.0][M.sub.0][N.sub.0]).

sinuosity, slope and height of triangular facets, spacing ratio, valley floor-valley height ratio) of the mountain fronts associated with potentially active faults are similar to those shown by the fronts related to faults that have produced destructive earthquakes (Hamblin, 1976; Bull and McFadden, 1977; Wallace, 1978; Keller and Pinter, 1996; Burbank and Anderson, 2001).
ADA obtains the maximum and the minimum [PHI] and [theta] angles between the reference facet and the relative facet by using the nine vectors between the vertices of each facet for targets modeled with triangular facets [21,22].
For example, consider a simple target modeled using a collection of triangular facets (Figure 1).
