The basic building block of the world is a Stack. Each stack is generated on the fly (if needed) and saved to a database. Coordinates are stored as a signed Long, providing a world with a maximum size of approximately 4,000,000x4,000,000x256.
Currently terrain is generated from the output of a simple FBM noise function, however plans for more varied terrain are in the works, pending testing and completion of basic world rendering.The world does not yet contain Mobiles (Monsters, NPCs, or Players) or Objects. Currently, the Client is responsible for world generation and world rendering. Plans are to split the client functionality into client and server programs.
The world has some basic lighting, but the current implementation is slightly buggy.The Material System is in place, although it's basic and simple. Plans are to have a varety of materials that mimic real-world materials (and a few that don't).
Currently world rendering is almost finished. As visible in the screenshot to the right, there are a few "Issues".
