Abstract: Logically-defined pixel interfaces and video frame transfer techniques are provided herein. In one example, a method includes receiving a video frame representing source pixels, where the video frame comprises logical pixels that each represent more than one source pixel according to a selected sizing and metadata that indicates the selected sizing for the logical pixels and indicators of which pixels included in the video frame comprise the logical pixels. The method also includes interpreting the metadata for the logical pixels to map each of the logical pixels across more than one output pixel according to the selected sizing and the indicators included in the metadata.

Abstract: Variable pixel rate video output and display techniques for computing systems and user devices are presented herein. In one example, a method of providing video data for display on a display device includes determining logical pixels with variable sizing that each represent one or more source pixels comprising at least a portion of a video frame. The method also includes producing metadata describing the variable sizing for the logical pixels, and transferring the metadata with data representing the logical pixels over a display interface for display of at least the portion of the video frame on the display device that maps the logical pixels across target pixels of the display device.

Abstract: A computer-implemented method for generating three-dimensional images by reusing multisample memory. Pixels corresponding to a first section of the overall display are multisampled. The multisampled pixel values corresponding to the first section of the display are stored in a multisample memory. The final pixel values corresponding to the first section of the display are stored in a frame buffer. Thereupon, multisampling is performed on those pixels belonging to a second section of the overall display. The same multisample memory is reused to store the multisampled pixel values corresponding to the second section of the display. In other words, the same piece of multisample memory is shared between the first and second portions of the display, thereby minimizing the amount of multisample memory that is needed. The final pixel values corresponding to the second section of the display are stored in the frame buffer. This process is repeated until multisampling has been performed over the entire display area.

Abstract: A method and apparatus provide for preserving hardware resources in connection with a display of complex scenes. Polygons which make up portions of the display can be culled prior to use of the hardware resources. An occlusion parameter for use in the culling operation can be determined in accordance with a monitoring of a plurality of tiles which constitute a display. In particular, a maximum depth value associated with a given tile can be utilized to indicate whether a subsequently received polygon or primitive would otherwise be occluded and should therefore be discarded or ignored rather than rasterized.
