Abstract

Systems and methods are disclosed for loading rendering data for a scene from a computer generated environment at an interactive computer simulation station. In accordance with one aspect of the present disclosure, a content file is created that defines, for each of a plurality of virtual geographical sectors of a computer generated environment, available levels of detail for the virtual geographical sector and a latest available version that the available levels of detail are contained in. A file associated with an available level of detail in the latest available version is listed in the content file. The content file is loaded into memory during execution of an interactive computer simulation station for real-time access by the interactive computer simulation station to determine which files are available to be loaded for rending of the scene having a target level of detail in a latest available version.

Claims19

Dependent claims

A method for loading rendering data for a scene from a computer-generated environment at an interactive computer simulation station, the method comprising:

providing a computer-generated environment database, on a disk, comprising for each of a plurality of virtual geographical sectors 1 to f distinct files describing the corresponding virtual geographical sector with distinct levels of detail collectively and with one of the distinct levels of detail individually;
defining a content file from the computer-generated environment database, the content file comprising metadata generated from the files describing each of the plurality of virtual geographical sectors, the metadata listing the distinct files describing the corresponding virtual geographical sectors of the computer-generated environment database and identifying for any given one of the virtual geographical sectors and any given one of the distinct levels of detail a corresponding one of the distinct files as providing a latest description of the given virtual geographical sector at the given level of detail;
during execution of an interactive computer simulation at the interactive computer simulation station, loading the content file into memory for real-time access;
during execution of the interactive computer simulation at the interactive computer simulation station, identifying a subset of s sectors that are relevant to the scene from the plurality of virtual geographical sectors;
and
for each sector si of the s sectors:
accessing the metadata of the content file in the memory to locate in real time one of the distinct files providing a latest description of the sector si at a target level of detail;
and
loading into the memory the located distinct file from the disk storing the computer-generated environment database,
wherein the target level of detail for at least one sector si of the s sectors is based on a type of the interactive computer simulation.
