摘要： Methods and apparatuses are disclosed for reporting texture footprint information. A texture footprint identifies the portion of a texture that will be utilized in rendering a pixel in a scene. The disclosed methods and apparatuses advantageously improve system efficiency in decoupled shading systems by first identifying which texels in a given texture map are needed for subsequently rendering a scene. Therefore, the number of texels that are generated and stored may be reduced to include the identified texels. Texels that are not identified need not be rendered and/or stored.

摘要： Techniques for rendering images on multiple tilted displays concurrently to mitigate perspective distortion are disclosed herein. According to one described approach, viewports are assigned to a center monitor and two peripheral monitors. Scene data for the viewports is calculated, and geometric primitives are generated for the viewports based on the scene data. Image transformation is performed based on a modified perspective value to modify geometry of the geometric primitives based on tilt angles of the displays, and the geometric primitives are rasterized using the modified geometry.

摘要： A system, method, and computer program product are provided for generating unique primitive identifiers. A specified scope and geometry for a scene is received. A primitive identifier is generated for each primitive of a particular type, where each of the primitive identifiers is unique within the specified scope, and where the primitives are generated as the geometry for the 3D graphics scene is processed by a graphics processing unit. Different types may include patches, triangles, and vertices. The specified scope may be one of a frame, region, pixel, or draw call.

摘要： A system, method, and computer program product are provided for shading primitive fragments. A target buffer may be recast when shaded samples that are covered by a primitive fragment are generated at a first shading rate using a first sampling mode, the shaded samples are stored in the target buffer that is associated with the first sampling mode and the first shading rate, a second sampling mode is determined, and the target buffer is associated with the second sampling mode. A sampling mode and/or shading rate may be changed for a primitive. A primitive fragment that is associated with a first sampling mode and a first shading rate is received and a second sampling mode is determined for the primitive fragment. Shaded samples corresponding to the primitive fragment are generated, at a second shading rate, using the second sampling mode and the shaded samples are stored in a target buffer.

摘要： One aspect provides a method for image correction. The method, in one embodiment, includes obtaining two or more simultaneously captured images of an object, wherein the two or more simultaneously captured images are of different perspectives of the object taken from an electronic device. The method, in this embodiment, further includes inputting the two or more simultaneously captured images into an image processing algorithm and generating a disparity map, and applying an image interpolation algorithm to the disparity map to obtain an interpolated image from a virtual camera location.

摘要： A multi-pass unit interoperates with a device driver to configure a screen space pipeline to perform multiple processing passes with buffered graphics primitives. The multi-pass unit receives primitive data and state bundles from the device driver. The primitive data includes a graphics primitive and a primitive mask. The primitive mask indicates the specific passes when the graphics primitive should be processed. The state bundles include one or more state settings and a state mask. The state mask indicates the specific passes where the state settings should be applied. The primitives and state settings are interleaved. For a given pass, the multi-pass unit extracts the interleaved state settings for that pass and configures the screen space pipeline according to those state settings. The multi-pass unit also extracts the interleaved graphics primitives to be processed in that pass. Then, the multi-pass unit causes the screen space pipeline to process those graphics primitives.

摘要： A system, method, and computer program product are provided for shading using a dynamic object-space grid. An object defined by triangle primitives in a three-dimensional (3D) space that is specific to the object is received and an object-space shading grid is defined for a first triangle primitive of the triangle primitives based on coordinates of the first triangle primitive in the 3D space. A shader program is executed by a processing pipeline to compute a shaded value at a point on the object-space shading grid for the first triangle primitive.
