  • Patent number: 8564606
    Abstract: A method and apparatus are provided to generate automatically a mip-map chain of texture images from a portion of texture image data such that it may be used in texturing a computer graphic image. A portion of the texture image data is stored temporarily and is filtered to generate at least one lower level of mip-map data from the texture data. This lower level of mip-map texture image data is then stored for use in texturing. Preferably these are stored on a tile-by-tile basis where a tile is a rectangular area of the image being displayed.

  • Patent number: 8558839
    Abstract: A system and method force a display device to receive the output produced by a graphics processing unit that is configured as the video graphics array (VGA) boot device for display of critical system screens. A hybrid computer system that includes multiple graphics processors configures a display multiplexor to select image data from one of the multiple graphics processing units for output to the display device. When a critical system event occurs and the graphics processing unit that is selected is not configured as the VGA boot device, system basic input/output system (BIOS) interfaces are used to configure the multiplexor to select the one graphics processing unit that is configured as the VGA boot device to output the critical system screen to the display device.

  • Patent number: 8502815
    Abstract: We present a method for predictive compression of time-consistent 3D mesh sequences supporting and exploiting scalability. The applied method decomposes each frame of a mesh sequence in layers, which provides a time-consistent multi-resolution representation. Following the predictive coding paradigm, local temporal and spatial dependencies between layers and frames are exploited for layer-wise compression. Prediction is performed vertex-wise from coarse to fine layers exploiting the motion of already encoded neighboring vertices for prediction of the current vertex location. Consequently, successive layer-wise decoding allows to reconstruct frames with increasing levels of detail.

  • Patent number: 8487943
    Abstract: Many computing device may now include two or more graphics subsystems. The multiple graphics subsystems may have different abilities, and may, for example, consume differing amount of electrical power, with one subsystem consuming more average power than the others. The higher power consuming graphics subsystem may be coupled to the device and used instead of, or in addition to, the lower power consuming graphics subsystem, resulting in higher performance or additional capabilities, but increased overall power consumption. By transitioning from the use of the higher power consuming graphics subsystem to the lower power consuming graphics subsystem, while placing the higher power consuming graphics subsystem in a lower power consumption mode, overall power consumption is reduced. A processor executes application software and driver software. The driver software includes first and second driver components for respectively controlling operation of the first and second graphics subsystems.
