Ringworld Terrain

From a Distance

This is a view looking down on the ring from a height of 1.3e7 km. From this distance, we begin to see some details in the terrain. The surface shader I created for the Ringworld produces large ocean areas surrounded by more finely grained land areas. The land areas use a color spline to choose from a set of greens and browns. The land texture also includes blue areas, to represent smaller bodies of water. Overlaying the surface texture is an fBm based cloud texture. The clouds are scaled about twice as large as the land features, and are stretched along the length of the ring, to indicate wind patterns.
