Abstract: Devices, systems, and techniques to incorporate lighting effects into computer-generated graphics. In at least one embodiment, a virtual scene comprising a plurality of lights is rendered by randomly sampling a set of lights from among the plurality of lights prior to rendering a frame of graphics. A subset of the set of lights is selected and used to render pixels within one or more portions of the frame.

Abstract: Disclosed are systems and methods for influencing the mood of a person using a synthetic window. The system includes storing one or more excitement scenes and one or more calming scenes, where the excitement scenes when displayed on the display produce an excitatory environment and the calming scenes when displayed on the display produce a calming environment. The system also includes receiving input as to a type of mood of the person, selecting an excitement scene or a calming scene in response to the mood type received, and displaying the selected scene on the display.

Abstract: A global illumination data structure (e.g., a data structure created to store global illumination information for geometry within a scene to be rendered) is computed for the scene. Additionally, reservoir-based spatiotemporal importance resampling (RESTIR) is used to perform illumination gathering, utilizing the global illumination data structure. The illumination gathering includes identifying light values for points within the scene, where one or more points are selected within the scene based on the light values in order to perform ray tracing during the rendering of the scene.

Abstract: Sampling a function is used for many applications, such as rendering images. The challenge is how to select the best samples to minimize computations and produce accurate results. An alternative is to use a larger number of samples that may not be carefully selected in an attempt to increase accuracy. For a function that is an integral, such as functions used to render images, a sample distribution may be computed by inverting the integral. Unfortunately, for many integrals, it is neither easy nor practical to compute the inverted integral. Instead, warp functions may be combined to provide a sample distribution that accurately approximates the factors of the product being integrated. Each warp function approximates an inverted term of the product while accounting for the effects of warp functions approximating other factors in the product. The selected warp functions are customized or “fitted” to implement importance sampling for the approximated product.

Abstract: A system, method, and computer program product are provided for reducing noise in an image using depth-based on sweeping over image samples. In use, each noisy pixel of an image having noise is identified. Additionally, for each noisy pixel, at least one sample included in each of a plurality of neighboring pixels to the noisy pixel is identified. Furthermore, the samples are swept over at least partially in a depth-based order to identify a value for the noisy pixel that reduces the noise.

Abstract: The present invention extends to methods, systems, and computer program products for representing polarized light in computer models. A rendering pipeline receives three dimensional modeling data (e.g., geometric primitives) for rendering a two dimensional image are received. The modeling data includes data representing a light source The light energy from the simulated transmission of particles at each pixel of the two dimensional image is calculated for any particles transmitted in an adjoint direction from a specified view point back to the light source. The light energies from each pixel are summed to calculate the total light energy present at the specified view point. The total light energy can be forwarded to other modules in rendering pipeline to more accurately render the two dimensional image, such as, for example, representing polarized light in the two dimensional image.
