摘要
Embodiments of the invention provide methods and systems to reduce the amount of space necessary to store a spatial index. According to embodiments of the invention, a spatial index may store pointers to information defining primitives which are located within bounding volumes defined by leaf nodes in the spatial index. The pointers may be smaller in size in contrast to information which defines the primitives, and the pointers may point to locations within a scene graph which contains information defining the primitives. Therefore, by storing pointers to primitives in the spatial index rather than the information which defines the primitives, the amount of space required to store the spatial index may be reduced.
