ABSTRACT:
A system for virtual environments in which graphical objects are depicted in a space to achieve the required high accuracy regardless of location through establishing locales or subdivisions of the global coordinate system and establishing an origin for each locale, such that the specification of position and movement of a graphical object in the locale can be made with greater precision than using a global coordinate system, thus eliminating the need for high-precision floating point processors or emulation. The system permits designers of virtual environments to work independently on their locales, with overlap being controlled through specifying distance between locale origins as well as relative orientation between the locales. The system also permits ignoring information from non-relevant distant locales to, minimize processing and network bandwidth requirements.
