Abstract:
1. A method comprising: calculating an area of interest for each of a plurality of objects to be simulated during a distributed simulation in which a plurality of computer systems operated by a plurality of users participate over a network, to produce a plurality of areas of interest; partitioning the plurality of objects into clusters of geographically proximate objects, wherein forming clusters includes: calculating an aggregate area of interest for each said one or more clusters of geographically proximate objects, wherein calculating an aggregate area of interest for each of the one or more clusters comprises calculating an aggregate area of interest for a cluster of objects as a function of peak velocity over a period of time of the object with the highest peak velocity within the cluster; and loading into a working memory those terrain pages from a terrain database that overlap with the aggregate area of interest for a predetermined cluster of geographically proximate objects; simulating each of the plurality of objects in a computer system in association with the terrain database by using the terrain pages, wherein the terrain database is too large to fit into the working memory of the computer system together with code and data needed for the simulation.
