Multi-mode parallel graphics rendering system employing real-time automatic scene profiling and mode control

Abstract: A multi-mode parallel 3-D graphics system having multiple graphics processing pipelines with multiple GPUs supporting a parallel graphics rendering process having time, frame and object division modes of operation, wherein each GPU comprises video memory, a geometry processing subsystem and a pixel processing subsystem, and wherein 3D scene profiling is performed in real-time, and the parallelization state/modes of the system are dynamically controlled to meet graphics application requirements. The multiple modes of parallel graphics rendering use real-time graphics application profiling, and dynamic control over time-division, frame-division, and object-division modes of parallel operation, within the same parallel graphics platform, which can be realized on PC-based computing system architectures.

An automatic mode controller automatically controls the mode of parallel operation of the parallel graphics rendering subsystem during the run-time of the graphics-based application.

Multi-mode parallel graphics rendering system (MMPGRS) embodied within a host computing system and employing the profiling of scenes in graphics-based applications

Abstract: Multi-mode parallel graphics rendering system (MMGRPS) embodied within a host computing system and employing the profiling of scenes in a graphics-based application. The MMPGRS supports multiple modes of parallel operation selected from the group consisting of object division, image division, and time division. A plurality of graphic processing pipelines (GPPLs) support a parallel graphics rendering process that employs one or more of the object division, image division and/or time division modes of parallel operation in order to execute graphic commands and process graphics data, and render pixel-composited images containing graphics for display on a display device during the run-time of the graphics-based application. An automatic mode control module automatically controls the mode of parallel operation of the MMPGRS during the run-time of the graphics-based application.

Internet-based graphics application profile management system for updating graphic application profiles stored within the multi-gpu graphics rendering subsystems of client machines running graphics-based applications

Abstract: A multi-user computer network, in which graphics performance of client machines running graphics-based applications is optimized using an automated Internet-based graphics application profile management system. The automated Internet-based graphics application profile management system includes an Internet-based communication server, operably connected to the infrastructure of the Internet, and to a central database server, through an application server. The central database server stores graphic application profiles (GAPs) for different graphics-based applications that are capable of running on the client machines. The graphics application profiles are stored in a profile database in the multi-GPU graphics rendering subsystem of each client machine. The Internet-based communication server communicates with each client machine over the Internet, and automatically programs updated graphics application profiles (GAPs) in the profile database of each client machine. This allows for the graphics performance of each client machine to be optimized during the run-time of the graphics-based applications.

Abstract: An “Interactive Virtual Display,” as described herein, provides various systems and techniques that facilitate ubiquitous user interaction with both local and remote heterogeneous computing devices. More specifically, the Interactive Virtual Display uses various combinations of small-size programmable hardware and portable or wearable sensors to enable any display surface (e.g., computer display devices, televisions, projected images/video from projection devices, etc.) to act as a thin client for users to interact with a plurality heterogeneous computing devices regardless of where those devices are located relative to the user. The Interactive Virtual Display provides a flexible system architecture that enables communication and collaboration between a plurality of both local and remote heterogeneous computing devices.

Image processing apparatus, image processing method and program

Abstract: An image processing apparatus includes a plurality of addition means and an image processing means. The addition means performs addition processing of adding pixels of a differential image at a second resolution representing a difference between an inputted image at a first resolution and an image at the second resolution higher than the first resolution as pixels of an inputted image at the second resolution. The image processing means is configured to perform second and subsequent addition processing, and generate an image of the second resolution as a processing result by performing the addition processing for a predetermined number of times. The addition processing is performed with inputs of an image at the first resolution and an image at the second resolution obtained by an immediately preceding addition processing, which are different from each other.

Parallel array architecture for a graphics processor

Abstract: A parallel array architecture for a graphics processor includes a multithreaded core array including a plurality of processing clusters, each processing cluster including at least one processing core operable to execute a pixel shader program that generates pixel data from coverage data; a rasterizer configured to generate coverage data for each of a plurality of pixels; and pixel distribution logic configured to deliver the coverage data from the rasterizer to one of the processing clusters in the multithreaded core array. The pixel distribution logic selects one of the processing clusters to which the coverage data for a first pixel is delivered based at least in part on a location of the first pixel within an image area. The processing clusters can be mapped directly to the frame buffer partitions without a crossbar so that pixel data is delivered directly from the processing cluster to the appropriate frame buffer partitions. Alternatively, a crossbar coupled to each of the processing clusters is configured to deliver pixel data from the processing clusters to a frame buffer having a plurality of partitions. The crossbar is configured such that pixel data generated by any one of the processing clusters is deliverable to any one of the frame buffer partitions.

Natural user input for driving interactive stories

Abstract: A system and method are disclosed for combining interactive gaming aspects into a linear story. A user may interact with the linear story via a NUI system to alter the story and the images that are presented to the user. In an example, a user may alter the story by performing a predefined exploration gesture. This gesture brings the user into the 3-D world of the displayed image. In particular, the image displayed on the screen changes to create the impression that a user is stepping into the 3-D virtual world to allow a user to examine virtual objects from different perspectives or to peer around virtual objects.
