    Abstract: Techniques are disclosed for processing graphics objects in a stage of a graphics processing pipeline. The techniques include receiving a graphics primitive associated with the graphics object, and determining a plurality of attributes corresponding to one or more vertices associated with the graphics primitive. The techniques further include determining values for one or more state parameters associated with a downstream stage of the graphics processing pipeline based on a visual effect associated with the graphics primitive. The techniques further include transmitting the state parameter values to the downstream stage of the graphics processing pipeline. One advantage of the disclosed techniques is that visual effects are flexibly and efficiently performed.

    Abstract: A system, method, and computer program product are provided for tiled deferred shading. In operation, a plurality of photons associated with at least one scene are identified. Further, a plurality of screen-space tiles associated with the at least one scene are identified. Additionally, each of the plurality of screen-space tiles capable of being affected by a projection of an effect sphere for each of the plurality of photons are identified. Furthermore, at least a subset of photons associated with each of the screen-space tiles from which to compute shading are selected. Moreover, shading for the at least one scene is computed utilizing the selected at least a subset of photons.

    Abstract: A system, method, and computer program product are provided for generating anti-aliased images. The method includes the steps of assigning one or more samples to a plurality of clusters, each cluster in the plurality of clusters corresponding to an aggregate stored in an aggregate geometry buffer, where each of the one or more samples is covered by a visible fragment and rasterizing three-dimensional geometry to generate material parameters for each sample of the one or more samples. For each cluster in the plurality of clusters, the material parameters for each sample assigned to the cluster are combined to produce the aggregate. The combined material parameters for each cluster are stored in an aggregate geometry buffer. An anti-aliased image may then be generated by shading the combined material parameters.

    Abstract: A remote device utilizes ray tracing to compute a light field for a scene to be rendered, where the light field includes information about light reflected off surfaces within the scene. This light field is then compressed utilizing one or more video compression techniques that implement temporal reuse, such that only differences between the light field for the scene and a light field for a previous scene are compressed. The compressed light field data is then sent to a client device that decompresses the light field data and uses such data to obtain the light field for the scene at the client device. This light field is then used by the client device to compute global illumination for the scene. The global illumination may be used to accurately render the scene at the mobile device, resulting in a realistic scene that is presented by the mobile device.

    Abstract: The present invention facilitates efficient and effective image processing. A network can comprise: a first system configured to perform a first portion of lighting calculations for an image and combing results of the first portion of lighting calculations for the image with results of a second portion of lighting calculations; and a second system configured to perform the second portion of lighting calculations and forward the results of the second portion of the lighting calculations to the first system. The first and second portion of lighting calculations can be associated with indirect lighting calculations and direct lighting calculations respectively. The first system can be a client in a local location and the second system can be a server in a remote location (e.g., a cloud computing environment). The first system and second system can be in a cloud and a video is transmitted to a local system.

    Abstract: Systems and methods are described for rendering complex surfaces or geometry. In at least one embodiment, neural signed distance functions (SDFs) can be used that efficiently capture multiple levels of detail (LODs), and that can be used to reconstruct multi-dimensional geometry or surfaces with high image quality. An example architecture can represent complex shapes in a compressed format with high visual fidelity, and can generalize across different geometries from a single learned example. Extremely small multi-layer perceptrons (MLPs) can be used with an octree-based feature representation for the learned neural SDFs.
