Abstract: An observation information processing apparatus calculates, for each mesh, a support and a confidence. The observation information processing apparatus generates an adjacent mesh set by merging adjacent ones of the meshes. The observation information processing apparatus calculates, based on a support and a confidence of each mesh included in the adjacent mesh set, a confidence for each adjacent mesh, and sets the smallest one of the confidences calculated as a new confidence threshold value. The observation information processing apparatus detects and excludes meshes to be excluded from meshes included in the adjacent mesh set, based on the confidences and supports of the meshes included in the adjacent mesh set and the confidence threshold value.

Abstract: In accordance with some embodiments, domain shader and/or tessellator operations can be eliminated when they are redundant. By using a corner cache, a check can determine whether a given corner, be it a vertex or a quadrilateral corner, has already been evaluated in the domain shader and/or tessellator and if so, the result of the previous operation can be reused instead of performing unnecessary invocations that may increase power consumption or reduce speed.

Abstract: This document describes systems and techniques for representing computer-generated objects with a limit mesh. In general, the systems and techniques may generate an object's form or appearance based on an estimation of how the object would look if shapes that form the object were infinitely subdivided to create a smooth surface for the object. For example, when a user views a distance object in a video game, its shape can be estimated by calculating an approximation of what the object would look like if the polygons that make up the object were infinitely divided. As the user approaches the object, curving solutions that may be embedded in the object can be used to construct curves for the object so that it appears smooth.

Abstract: A game apparatus generates an image of a three-dimensional virtual space as viewed from a predetermined viewpoint, an object being provided in the three-dimensional virtual space. Next, the game apparatus obtains a depth value (Z value) indicating a depth from the viewpoint in a line-of-sight direction in the three-dimensional virtual space for each pixel of the image. Further, the game apparatus detects a pixel corresponding to a contour of the object based on the depth value. Specifically, a plurality of pixels are specified as reference pixels. It is determined whether or not a pixel of interest corresponds to a contour, based on a change level of differences in depth value between the pixel of interest and the reference pixels.

Abstract: A method of calculating performance parameters for a type of data being executed by a unified processing subunit. In one embodiment, a task (e.g., a draw call) is executed by a processing pipeline (e.g., a GPU). An ALU within a unified processing subunit (e.g., a unified shader processing unit) is queried to determine a type of data (e.g., vertex processing, pixel shading) being processed by the ALU. Performance parameters (e.g., bottleneck and utilization) for the type of data being processed by the ALU is calculated and displayed (e.g., stacked graph). Accordingly, software developers can visualize component workloads of a unified processing subunit architecture. As a result, utilization of the unified processing subunit processing a particular data may be maximized while bottleneck is reduced. Therefore, the efficiency of the unified processing subunit and the processing pipeline is improved.
