TIN/Voronoi
TIN/Voronoi geoprocess computes Delaunay triangulation or Voronoi tessellation from a mess.
gvSIG's geoprocess implementation uses a plugin based extensible architecture. This allows to extend the tools with new plugins wich implements new delaunay algorithms. This gvSIG geoprocess introduces a novelty: users could triangulate layers of any kind of geometry type: points, lines or polygons. To do that, each layer must provide a triangulation insertion point for each of its geometries. By default, linear and polygon layers' geometries use the first point of the geometry. Plugins could extend this policy, providing lines mid point, polygon centroid, etc. as insertion point.
