Alt.GDC: Earth’s Digital Doppelganger

Creating photo-realistic game environments on a massive scale, by hand, can be beyond time consuming. Just ask the environment artists at Bethesda Studios after crafting the epic world of Skyrim. The alternative is to create algorithms that generate a virtually endless world that’s different every time you load a new game, as in Minecraft. But these algorithms can often produce strange, unrealistic landforms, like impossible overhangs and floating islands. While these surreal structures are part of the charm of Minecraft’s cartoony procedural landscape, if realism is your goal, this isn’t going to fit the desired aesthetic.

The Outerra engine, a project that’s been in development for years, has found a unique solution to the problem of generating massive, photo-realistic environments: Base them on real data from Earth. All of Earth. These sprawling vistas look completely natural because, in a sense, they are. The large scale structures of mountains, rivers, and oceans use height-map data dynamically downloaded as you explore, while the ground-level detail is procedurally generated, leaving you free to view the world as close or as far away as you desire (presumably within the limits of your processor).

The first game being built using this engine, Anteworld, presents an Earth long abandoned by humanity and tasks players with rebuilding civilization. With potential features including asynchronous content propagation (i.e. you build your city in a single player mode and it automatically loads your creations into all other players’ Earths) and direct multiplayer modes, which allow you to play directly with others online, Anteworld is possibly shaping up to be the Second Life I’ve always dreamed of.

  1. More Simplex and Perlin garbage. No erosion passes, water or wind. Nothing new in that video that wasn’t done back in the 80s let alone 90s.

    1. Actually, no Simplex and no Perlin. Since it uses real earth data and only the details smaller than 90m are filled in using procedural algos, there’s plenty of original erosion of our planet visible. For those who look before posting, that is.

  2. “…you build your city in a single player mode and it automatically loads your creations into all other players’ Earths”
    Does anyone remember when Spore did this? All that was created were rude, over exaggerated phalluses. I thought all game designers learned their lesson on this one: Never let the players have a one way communication channel.
