    摘要： A device implementing a system for managing multi-modal rendering of application content includes at least one processor configured to receive content, provided by an application running on a device, for displaying in a three-dimensional display mode. The at least one processor is further configured to determine that the content corresponds to two-dimensional content. The at least one processor is further configured to identify a portion of the two-dimensional content for enhancement by a three-dimensional render. The at least one processor is further configured to enhance, in response to the determining, the portion of the two-dimensional content by the three-dimensional renderer. The at least one processor is further configured to provide for display of the enhanced portion of the two-dimensional content on a display of the device in the three-dimensional display mode.

    摘要： Various implementations disclosed herein include devices, systems, and methods that enable a device to provide a view of virtual elements and a physical environment where the presentation of the virtual elements is based on positioning relative to the physical environment. In one example, a device is configured to detect a change in positioning of a virtual element, for example, when a virtual element is added, moved, or the physical environment around the virtual element is changed. The location of the virtual element in the physical environment is used to detect an attribute of the physical environment upon which the presentation of the virtual element depends. Thus, the device is further configured to detect an attribute (e.g., surface, table, mid-air, etc.) of the physical environment based on the placement of the virtual element and present the virtual element based on the detected attribute.

    摘要： Systems, methods and program storage devices are disclosed, which comprise instructions to cause one or more processing units to analyze input images to a texture atlas and determine how each texture should be modified before being stored in the texture atlas to prevent undesirable drawing artifacts. For example, “tileable” images may be identified on a per-edge basis (e.g., by determining whether each edge pixel is above a certain opacity threshold). The tileable images may then be modified, e.g., by extruding a 1-pixel border identical to the outer row of pixels, before being stored in the texture atlas. “Character”-type sprites may also be identified on a per-edge basis (e.g., by determining whether each edge pixel is below the opacity threshold). The character-type sprites may then by modified by adding a single pixel transparent border around the outer rows of pixels before being stored in the texture atlas.

    摘要： Systems, methods and program storage devices are disclosed, which comprise instructions to cause one or more processing units to dynamically generate refined normal maps for 2D texture maps, e.g., supplied by a programmer or artist. Generally speaking, there are two pertinent properties to keep in balance when generating normal vectors comprising a normal map: “smoothness” and “bumpiness.” The smoothness of the normal vectors is influenced by how many neighboring pixels are involved in the “smoothening” calculation. Incorporating the influence of a greater number of neighboring pixels' values reduces the overall bumpiness of the normal map, as each pixel's value takes weight from those neighboring pixels. Thus, the techniques described herein iteratively: downsample height maps; generate normal maps; scale the normal maps to maintain bumpiness; and blend the generated scaled normal maps with generated normal maps from previous iterations—until the smoothness of the resultant normal map has reached desired levels.

    摘要： Systems, methods, and computer readable media to improve the operation of graphics systems are described. In general, collision avoidance techniques are disclosed that operate even when the agent lacks a priori knowledge of its environment and is, further, agnostic as to whether the environment is two-dimensional (2D) or three-dimensional (3D), whether the obstacles are convex or concave, or whether the obstacles are moving or stationary. More particularly, techniques disclosed herein use simple geometry to identify which edges of which obstacles an agent is most likely to collide. With this known, the direction of an avoidance force is also known. The magnitude of the force may be fixed, based on the agent's maximum acceleration, and modulated by weighting agents.

    摘要： The disclosure pertains to the operation of graphics systems and to a variety of architectures for design and/or operation of a graphics system spanning from the output of an application program and extending to the presentation of visual content in the form of pixels or otherwise. In general, many embodiments of the invention envision the processing of graphics programming according to an on-the-fly decision made regarding how best to use the specific available hardware and software. In some embodiments, a software arrangement may be used to evaluate the specific system hardware and software capabilities, then make a decision regarding what is the best graphics programming path to follow for any particular graphics request. The decision regarding the best path may be made after evaluating the hardware and software alternatives for the path in view of the particulars of the graphics program to be processed.
