By Brett Wiesner - Recently I gave a presentation at IMAGE 2011 in Scottsdale, Arizona and at an NDIA meeting in Fairfax, Virginia on the benefits of Open Streaming Terrain (OST). I thought I’d share just a brief synopsis of that here.
Terrain databases are an important part of any simulation and there are four main approaches for building terrain databases. You have hand modeled terrains that are built by artists and 3D modelers. There are tool generated terrain databases that are built by terrain generation tools. You have direct from source terrains that are constructed on the fly from source data in the client application. And finally you have streaming terrain, where content is streamed from a sever to a client directly. Each of these terrain approaches has its advantages and drawbacks.
