Abstract: Downsampling based display method and apparatus are provided. An input image including multiple pixels is obtained. At least two pixels neighboring with a to-be-calculated DS pixel on each of at least two directions from the pixels are obtained to get at least four first neighboring pixels. Theoretical values of each first neighboring pixel on the at least two directions are calculated. Errors of the theoretical values of each first neighboring pixel and a corresponding original value are obtained. Weight coefficients for calculating the DS pixel are determined according to the errors. An estimation value of the DS pixel is calculated according to the weight coefficients and the weighted cubic interpolation calculation model. As to the other DS pixels of target image, corresponding estimation values are calculated using the above steps, and then a downsampling processed image is obtained. The color aliasing is avoided and sharp image is obtained.

Abstract: A SIMD processing unit processes a plurality of tasks which each include up to a predetermined maximum number of work items. The work items of a task are arranged for executing a common sequence of instructions on respective data items. The data items are arranged into blocks, with some of the blocks including at least one invalid data item. Work items which relate to invalid data items are invalid work items. The SIMD processing unit comprises a group of processing lanes configured to execute instructions of work items of a particular task over a plurality of processing cycles. A control module assembles work items into the tasks based on the validity of the work items, so that invalid work items of the particular task are temporally aligned across the processing lanes. In this way the number of wasted processing slots due to invalid work items may be reduced.

Abstract: A computer-based system forms a more accurate intensity value for virtual light reflected from computer-generated images. The reflected light intensity from the images is computed pixel by pixel using the mean and variance of the depth values of a filter region associated with the pixel, as well as the maximum and minimum values of the depth values in the filter region. The computations use the normalized, incomplete beta function algorithm.

Abstract: Technologies are presented that optimize graphics power-performance efficiency. A method of graphics processing may include beginning a graphics workload with a first voltage and a first clamping threshold; monitoring amounts of time that bursts of dynamic capacitance remain above the first clamping threshold; and, if the dynamic capacitance remains above the first clamping threshold for more than a predetermined time threshold, setting the voltage to a second voltage and setting the clamping threshold to a second clamping threshold until the end of the frame. If, at the end of an initial frame, a number of clock cycles from a start of the frame to when the predetermined time threshold is exceeded is less than a predetermined minimum number of clock cycles, the second clamping threshold and the second voltage may be maintained for processing of a predetermined number of subsequent frames.

Abstract: A conversion between two texture compression formats comprises calculations performed at index-level for reducing handling of values with color bit-length and an amount of calculations with color values. Format conversion can thus be performed in real time upon displaying an image using the compressed texture data, without significant slowing down of a display rate of the images. It may be implemented in particular for conversion from DXT1—to ETC1 compression format, and a non-flipped or flipped orientation of an ETC1—compressed texture data block can thus be determined from said texture data block as initially compressed in DXT1 format.

Abstract: A method, system, and computer program product for moving objects such as a display window about a display frame by combining classical mechanics of motion. A window nudging method commences by receiving a discrete user interface gesture from a human interface device such as a mouse click or a keystroke, and based the discrete user interface gesture, instantaneously accelerating the window object to an initial velocity. Once the window is in motion, then the method applies a first animation to animate the window object using realistic motion changes. Such realistic motion changes comprise a friction model that combines sliding friction with fluid friction to determine frame-by-frame changes in velocity. The friction model that combines sliding friction with fluid friction can be applied to any object in the display frame. Collisions between one object and another object or between one object and its environment are modeled using a critically-damped spring model.
