Program to create a vector delaunay triangulation from a sites
file. Delaunay triangualtion is based on the 'hull' software, by
Ken Clarkson (clarkson@research.att.com
). See the directory hull
for more details.
Jo Wood, Department of Geography. 19th July, 1995. ---------- Modified to use the GRASS 4.2 sites API. Allows x,y,z,attribute format for sites files. This enables a single sites file to carry all necessary information for TIN construction. Modified to allow VRML 1.0 output as indexed face set. Jo Wood, 4th September, 1996 ---------- Modified to allow vertical scaling of elevation values. Jo Wood, 23rd July, 1997 ---------- TODO: Constrain triangulation along channels and ridges. ---------- Usage: s.delaunay [-v] in=name out=name [zscale=value] Flags: -v Create VRML 1.0 output Parameters: in Sites file to process out Vector map layer to contain delaunay triangulation. zscale Vertical scaling of elevation. default: 1.0
