TIN mesh generation
To generate a TIN grid, PIHM using a Delaunay triangulation algorithm. Our goal is to create a grid with ~1000 triangles for efficient processing. Lakes may be removed, or left in as areas of constant surface head.
Below is our initial grid, showing the river segments and simplified lake polygons.
