Static geo LOD system

December 10, 2005

   To allow us to create a city of massive complexity, it was necessary to create an LOD system to help the game handle the poly counts without grinding to a halt. We decided on a system that welds the ground and all the buildings and other large objects into one giant mesh. At that point we can alter the poly density on the fly so that as object move away or get closer they morph through various complexities of polygons, less with distance, more as you get closer. This system is being added to the Trident3D engine, and art is making the static models so that they can be welded together automatically by the engine.
