1. A computing system, comprising: a memory configured to store a three-dimensional (3D) clipmap data structure having at least one clip level and at least one mip level, wherein said 3D clipmap data structure comprises a mipmap data structure having a plurality of levels that span a scene and compose said at least one clip level and said at least one mip level, said plurality of levels respectively associated with a plurality of memory pages and said at least one clip level maps less than all of said plurality of memory pages; and a processor configured to generate voxelized data for a scene and cause said voxelized data to be stored in said 3D clipmap data structure.
