CONTENT GENERATION SYSTEMS AND APPLICATIONS USING OCTREE-BASED SPATIAL DATABASES

Approaches presented herein provide for the generation and maintenance of a minimally-sized octree (or other spatial representation) for an arbitrary or dynamic dataset. An octree representation allows for efficient real-time querying of dynamic content, where such a spatial database can scale from a single machine to multiple machines. Objects in a scene can be stored to the spatial database using a set of spatial primitives. When a first object (or set of objects) in a scene is determined, an initial octree and root can be determined based at least in part upon the size and location of the object(s). An additional object may be added that is outside the existing root of the octree. A new bounding volume is generated that surrounds this new object, and the bounding volume is grown in alternating directions until the bounding volume also includes the other objects in the environment, and this new volume boundary becomes the new root of an updated octree for this environment.
