A method, system, and computer program product for performing a lighting simulation are disclosed. The method includes the steps of receiving a three-dimensional (3D) model, receiving a set of probes, where each probe specifies a location within the 3D model and an orientation of the probe, and performing, via a processor, a lighting simulation based on the 3D model, the set of probes, and one or more light path expressions. The light path expressions are regular expressions that represent a series of events, each event representing an interaction of a ray at a location in the 3D model.

Lighting simulation analysis using light path expressions

A system, method, and computer program product are provided for computing values for pixels in an image plane. In use, a low discrepancy sequence associated with an image plane is identified. Additionally, a function with the set of pixels of the image plane as a domain is determined. Further, a value is computed for each pixel in the image plane, utilizing the low discrepancy sequence and the function with the set of pixels of the image plane as a domain.

System, method, and computer program product for tiled screen space sample scrambling for parallel deterministic consistent light transport simulation

Embodiments of the present invention are directed to methods and a system that allow for deterministic parallel low discrepancy sampling, which can be efficiently processed, and are effective in removing transitionary artifacts that occur in low-dimensional projections generated in low discrepancy sequences. Embodiments of the claimed subject matter further provide improvements upon the low-dimensional projections and thus the visual quality when using the Sobol' sequence for image synthesis.

System and process for improved sampling for parallel light transport simulation

A system, method, and computer program product are provided for performing ray tracing. In use, ray tracing is performed utilizing a divide and conquer method, where the divide and conquer method is associated with a cache.

System, method, and computer program product for performing ray tracing

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.
