摘要： A system and method are disclosed for rendering polygons. Parameter values may be rendered for only one sample position of a plurality of neighboring sample positions within a polygon. The parameter values rendered for the one sample position may then be transmitted to one or more memories and conditionally stored in a plurality of memory locations that correspond to the plurality of neighboring sample positions. Transmitting parameter values to one or more memories may be achieved in a single transaction. Depth values may be rendered for each sample position in the plurality of neighboring sample positions. Depth value data may be compressed. In some embodiments, the one or more memories may be configured to determine depth values for each of the neighboring sample positions.

摘要： A graphics system and method for increasing efficiency of decompressing blocks of compressed geometry data and reducing redundant transformation and lighting calculations is disclosed. Multiple decompression pipelines are used to increases the decompression speed. A control unit receives blocks of compressed geometry data information and selectively routes them to a plurality of decompression pipelines. Each decompression pipeline is configured to decompress the blocks into a set of vertices. The reduction in redundant calculations is accomplished by delaying the formation of geometric primitives until after transformation and lighting has been performed on the vertices. Transformation and/or lighting are performed independently on a vertex-by-vertex basis without reference to which geometric primitives the vertices belong to. After transformation and or lighting, geometric primitives may be formed utilizing previously generated connectivity information. The connectivity information may include mesh buffer references, vertex tags, or other types of information.

摘要： An apparatus and method for splitting vertex streams relating to graphics data into substreams, and processing the substreams in parallel. A graphics subsystem of a computer system includes a vertex splitting module, which determines whether incoming vertex streams are of a unicast, unlocked type, and thus available for splitting, and further whether graphics primitives in the vertex stream are of a type that may be split. If appropriate, the vertex splitting module then locates vertices in the vertex stream, generates substreams from the vertex stream, and transmits the substreams in a load-balanced operation to multiple graphics processors for parallel processing and outputting to an output device. If the vertex stream is too large to store in FIFO queues of the graphics processors, it is not split into substreams.

摘要： A graphics system comprising a series of calculation units. The calculation units comprise a first subset and a second subset of calculation units. A first calculation unit of the series generates a first digital video stream and a second digital video stream. Each calculation unit of the first subset: (a) passes the second digital video stream to a next calculation unit of the series unmodified; and (b) computes first pixel values, injects or mixes the first pixel values into the first digital video stream, and passes the modified first digital video stream to the next calculation unit. Similarly, each calculation unit of the second subset injects or mixes second pixel values into the second digital video stream, and passes the first digital video stream unmodified. A last calculation unit of the series drives one or more display devices in response to the first and second digital video streams.

摘要： A system and method for performing color correction based on physical measurements (or estimations) of color component spectra (e.g. red, green, blue color component spectra). A color correction system may comprise a spectrum sensing device, a color calibration processor, and a calculation unit. The spectrum sensing device may be configured to measure color component power spectra for pixels generated by one or more display devices on a display surface. The color calibration processor may receive power spectra for a given pixel from the spectrum sensing device and compute a set of transformation parameters in response to the power spectra. The transformation parameters characterize a color correction transformation for the given pixel. The color calibration processor may compute such a transformation parameter set for selected pixels in the pixel array. The calculation unit may be configured to (a) compute initial color values for an arbitrary pixel in the pixel array, (b) compute modified color values in response to the initial color values and one or more of the transformation parameter sets corresponding to one or more of the selected pixels, and (d) transmit the modified color values to the display device.

摘要： A method and computer graphics system capable of implementing multiple pipelines for the parallel processing of graphics data. For certain data, a requirement may exist that the data be processed in order. The graphics system may use a set of tokens to reliably switch between ordered and unordered data modes. Furthermore, the graphics system may be capable of super-sampling and performing real-time convolution. In one embodiment, the computer graphics system may comprise a graphics processor, a sample buffer, and a sample-to-pixel calculation unit. The graphics processor may be configured to receive graphics data and to generate a plurality of samples for each of a plurality of frames. The sample buffer, which is coupled to the graphics processor, may be configured to store the samples. The sample-to-pixel calculation unit is programmable to generate a plurality of output pixels by filtering the rendered samples using a filter.

摘要： A computer graphics system that utilizes a super-sampled sample buffer and a sample-to-pixel calculation unit for refreshing the display. The graphics system may have a graphics processor, a super-sampled sample buffer, and a sample-to-pixel calculation unit. The graphics processor renders samples into the sample buffer at computed positions or locations in the sample buffer. The graphics system may utilize a window ID that specifies attributes of pixels on a per object basis. The window ID may specify one or more of a sample mode, filter type, color attributes, or source attributes. The sample mode may include single sample per pixel mode and multiple samples per pixel mode. In implementing a single sample per pixel mode, the graphics system may be further operable to generate a single sample per pixel for certain windows of the screen in order to, for example, provide backwards compatibility with legacy systems with no multi-sampling support. The graphics system may generate samples that have the same value within the region of a single pixel, or the graphics system may utilize a very narrow filter that only selects the center sample in the averaging process.

The sample buffer interface is configured to (a) buffer N streams of samples in N corresponding input buffers, wherein N is greater than or equal to two, (b) store N sets of context values corresponding to the N input buffers respectively, (c) terminate transfer of samples from a first of the input buffers to the programmable sample buffer, (d) selectively update a subset of state registers in the programmable sample buffer with context values corresponding to a next input buffer of the input buffers, (e) initiate transfer of samples from the next input buffer to the programmable sample buffer. The context values stored in the state registers of the programmable sample buffer determine the operation of an arithmetic logic unit internal to the programmable sample buffer on samples data.

摘要： A graphics system comprises a rendering unit, a sample buffer, and a sample-to-pixel calculation unit. The rendering unit receives vertices defining a triangle, and generates first and second octant identifier words for first and second edges of the triangle respectively. In most cases, the two octant identifier words determine the triangle orientation. However, in a few special cases (i.e. when the octant identifier words specify the same or opposite octants), the triangle orientation is resolved based on a comparison of the slopes of the first and second edge. Further rendering operations on the triangle may be conditioned on the value of the triangle orientation. The triangle orientation may be used to determine the interior side of each triangle edge. Sample positions falling on the interior side of all three edges are labeled as interior samples. Color values are computed for interior samples.
