What is the vertical resolution of the terrain? From the videos, it looks something like 1m, is that right? Are there any limits to how deep or high the terrain can go?
Second, as far as I understand, the terrain is basically made of vertices each with a distance from the center of the planet and a terrain type. Would it be theoretically possible to have several layers of terrain, eg. dirt above rock, or even ores and caves? I think that could add a lot to the realism, although it could probably get rather hardware-hungry.
Lastly, are there / will there be different kinds of a specific type of terrain? Like high and rocky (young) v. lower and smooth (older) mountains, mesas, canyons, rock formations, sand dunes etc? I think it’s pretty important to have not only a biological, but also geological variety, especially in a world as large as this.
