Abstract

A system, method, and computer program product are provided for deterministically simulating light transport. In use, all pairs of non-negative integers are enumerated (e.g. in a predetermined order). Additionally, for each of the enumerated pairs of non-negative integers, an associated pair of a query point and a photon is identified by: identifying a query point associated with a first non-negative integer of the pair of non-negative integers using a deterministic point sequence of query points and identifying a photon associated with a second non-negative integer of the pair of non-negative integers using a deterministic point sequence of photons. Further, for each of the query points in the deterministic point sequence of query points, photons in the deterministic point sequence of photons associated with the query point are identified. Still yet, an illumination value is computed for each query point of each of the photons associated with the query point using the pairs of query points and photons and at least one transport property at the query point.
