Triangulation

Hello GrassUsers:

        I want to interpolate a scarse data points, but well choised, to set
a raster map. These points are localited in change zones.
        For this I want first to make a interpolation of triangulation type,
to create a thing similar to a TIN and from this to interpolate to a coarse
grid. Subsequently to reinterpolate this grid to a more fine grid with
"s.surf.tps" for smooth.

PROBLEM: Running "s.geom operation=delaunay" I obtain a vector map with
triangular polygons whose category (dig_cats) is the Z value of the 3 vertex
of this triangle. When I convert this vectorial map to raster with
"v.to.rast", it creates a raster map which reflects the previous polygons;
beeing the category cell too the Z values of the original vertex.
        I want to know how can I use the vectorial map created by "s.geom"
to obtain a raster map, where every cell have as category their corresponding
Z value in the tridimensional triangular surface built by the original
vertexs.

        Thanks in advance.
