摘要： A system, method and computer program product are provided for transparency rendering in a graphics pipeline. Initially, colored-transparency information is collected from a plurality of depth layers (i.e. colored-transparency layers, etc.) in a scene to be rendered. The collected colored-transparency information is then stored in memory. The colored-transparency information from the depth layers may then be blended in a predetermined order.

摘要： Hybrid sampling of pixels of an image involves generating shading values at multiple shading sample locations and generating depth values at multiple depth sample locations, with the number of depth sample locations exceeding the number of shading sample locations. Each shading sample location is associated with one or more of the depth sample locations. Generation and filtering of hybrid sampled pixel data can be done within a graphics processing system, transparent to an application that provides image data.

摘要： One embodiment of the invention sets forth a CROP configured to perform both color raster operations and atomic transactions. Upon receiving an atomic transaction, the distribution unit within the CROP transmits a read request to the L2 cache for retrieving the destination operand. The distribution unit also transmits the source operands and the operation code to the latency buffer for storage until the destination operand is retrieved from the L2 cache. The processing pipeline transmits the operation code, the source and destination operands and an atomic flag to the blend unit for processing. The blend unit performs the atomic transaction on the source and destination operands based on the operation code and returns the result of the atomic transaction to the processing pipeline for storage in the internal cache. The processing pipeline writes the result of the atomic transaction to the L2 cache for storage at the memory location associated with the atomic transaction.

摘要： An apparatus and method for converting color data from one color space to another color space. A driver determines that a set of shader program instructions perform a color conversion function and the set of shader program instructions are replaced with either a single shader program instruction or a flag is set within an existing shader program instruction to specify that output color data is represented in a nonlinear color format. The output color data is converted to the nonlinear color format prior to being stored in a frame buffer. Nonlinear color data read from the frame buffer is converted to a linear color format prior to shading, blending, or raster operations.

摘要： Multiple output buffers are supported in a graphics processor. Each output buffer has a unique identifier and may include data represented in a variety of fixed and floating-point formats (8-bit, 16-bit, 32-bit, 64-bit and higher). A fragment program executed by the graphics processor can access (read or write any of the output buffers. Each of the output buffers may be read from and used to process graphics data by a fragment shader within the graphics processor. Likewise, each output buffer may be written to by the graphics processor, storing graphics data such as lighting parameters, indices, color, and depth.

摘要： Systems and methods for dynamically canceling texture fetches may improve texture mapping performance. A shader program compiler inserts condition code writes and condition code comparison operations for shader program instructions that contribute to a texture read instruction and do not need to be executed if certain conditions are met. During execution of the shader program, the inserted condition codes are used to compute a dynamic writemask that indicates if the texture data resulting from the texture read is unnecessary. The dynamic writemask is used to cancel unnecessary texture fetches during execution of the shader program.

摘要： A method for synchronizing divergent samples in a programmable graphics processing unit is described. In one embodiment, the method includes the steps of determining that a divergence has occurred and detecting that a first sample of a group of samples has encountered a first synch token. The method also includes the steps of determining whether each of the other samples of the group has encountered a synch token and determining whether the synch token encountered by each of the other samples of the group is the first synch token.

摘要： A fragment program may configure a fragment processor to compute several output positions and associated data for a fragment, effectively scattering the fragment. Each output position may be independent of a position computed for the fragment during rasterization of a primitive. Each output position may be computed based on a point light source position to compute a shadow map corresponding to the point light source. A raster operation unit writes processed fragment data to each output position. Furthermore, the fragment program may configure the fragment processor to compute per-output position parameters for the fragment such as stencil and alpha values.

摘要： A fragment program may configure a fragment shader to compute a destination position for a fragment, where the destination position is independent of a position computed for the fragment during rasterization of a primitive. The destination position may be computed based on fragment parameters such as color, depth, and transparency. A raster operation unit writes processed fragment data to the destination position. Furthermore, the fragment program may configure the fragment shader to compute a per-fragment stencil operation for use by the raster operation unit during stencil buffering.
