ABSTRACT:
A system and method for storing a data representative of an object in various LODs. Each LOD representation is divided into a plurality of LOD cells and stored in a secondary memory. A designer designates a set of LOD cells with each of the plurality of LOD cells. When the projection of an eye point falls within a subject LOD cell, the set of LOD cells designated with the subject LOD cell are retrieved into a system memory. Thus, by properly designating the set of LOD cells, the designer may ensure that the desired LOD cells are in the system memory when required for processing. As a result, the data in the LOD cells may be accessed at a relatively high rate from the system memory when processing the LOD data. As only the required cells are retrieved into the system memory, the amount of memory required for storing the LOD data is also minimized.
