DYNAMICO Mesh

This example demonstrates how to render an unstructured hexagon/pentagon mesh.

📋 Summary

Creates a mesh from 2-D latitude and longitude unstructured cell bounds.

The resulting mesh contains hexagonal cells tessellated around 12 pentagon cells, which are centered over the 12 vertices of a base icosahedron.

It uses surface air pressure data from the DYNAMICO project, a new dynamical core for the Laboratoire de Météorologie Dynamique (LMD-Z), the atmospheric General Circulation Model (GCM) part of Institut Pierre-Simon Laplace (IPSL-CM) Earth System Model. The data targets the mesh faces/cells.

Note that, a graticule and Natural Earth coastlines are also rendered.
