<p>Disclosed is a system for creating an image. The system includes a processor and a memory, comprising a program configured to cause the processor to perform certain steps. The steps include receiving a ray (313) of a set of rays such that the ray (313) has an origin (303) and a direction (301). The rays are then sorted into a directional group of a plurality of directional groups, each group having a corresponding directional range and comprising rays of the set of rays having directions within the corresponding directional range. A base of the conical boundary is generated such that the base encircles a ray origin of a ray of the directional group that is closest to the apex in the average direction dimension.</p> |
