3 types of grid Ive explored:
Delaunay triangulation: works like voronoi in linking up the space into a fixed geometry and, like voronoi, picks up the area densities. This test was done from the poins from the splitting tributaries of the Greenborough Marsh in the estuary.

Regular mesh derived from points: this one is very good although Im having problems getting the direction of the diagonal segments, still… it resembles the NetLogo 3D one which is good to show deformation and variation in topography consistenly and uniformly.

Displacement bump map in rhino… this one is not working for SR2 issues with my Rhino, but Im working on it to make it work!
