ABSTRACT:
The present invention is an improved flight simulation system. The system organizes data based upon a predetermined number of object types. Each scenery file is divided to separate the data for each object type. Object data is sub-divided into latitude bands of a fixed range of latitude. The system selectively analyzes the latitude band data to locate objects to be processed. For each object type, the objects within a latitude band are sorted and analyzed from west to east. The present system also includes a seeded scenery system. Various levels of seeds, each seed size referring to the size of the area covered by each seed are used. The seeded scenery system provides background scenery only when no other scenery is available to overwrite it. The system also includes a dynamic overlay management system which, when it loads a routine into memory, rewrites the line of code which called the routine to be a call directly to the location of the routine which is now in memory.
