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.

A system, method, and computer program product are provided for focusing computing power to a region of interest that can be changed interactively and arbitrarily during the process of image synthesis. In operation, a problem domain is partitioned utilizing a first selected technique. Additionally, a number of samples to be drawn per partition are assigned utilizing a second selected technique. Furthermore, the assigned number of samples are drawn for each partition, where the samples are generated by only one deterministic sample sequence. Still yet, the partitioning, assigning, and drawing are capable of being repeated such that existing partitions and assignments are capable of remaining unchanged during sampling and a convergence speed is adapted without compromising convergence in at least one of a sequential computing environment or a parallel computing environment. In this way, the convergence of image synthesis is not compromised. In fact, the image synthesis process may converge to the same solution that would have been obtained without interaction.

A system, method, and computer program product are provided for efficiently ray tracing micropolygon or other highly complex geometry. In operation, a first hierarchy of a plurality of objects is established. Additionally, rays are traced using the first hierarchy to efficiently identify which of the plurality of objects are potentially intersected. Furthermore, at least one of the potentially intersected objects are decomposed, on-demand, into a set of subobjects, each set of subobjects corresponding to one of the at least one of the potentially intersected objects. Still yet, a second hierarchy is established for at least one of the set of subobjects, the second hierarchy being determined by a connectivity of subobjects in an associated set of subobjects in order to accelerate ray tracing.
