<p>A system and method are described for processing three-dimensional data by loading the three-dimensional data for a first region into memory, the data being based on a first coordinate system. Additional three-dimensional data for an adjacent second region is also loaded into memory, the additional data being based on a second coordinate system. The data is rendered using both the three-dimensional data for the first region and the three-dimensional data for the adjacent second region. The three-dimensional data may contain a region, a portal and a delegator. When the three-dimensional data for an adjacent second region is loaded from a second memory the portal points to the delegator which includes a pointer to the three-dimensional data for the adjacent second region. Each region may have portals linking the region to adjacent regions. The regions may be stored in separate memories and managed by delegators. The delegator is capable of addressing regions and transforming coordinate systems. Regions in computer memory are processed by a garbage collector, the garbage collector works in conjunction with the delegator, to effectively manage computer memory used to store very large virtual reality worlds.</p> |
