摘要： Digital Image compositing using a programmable graphics processor is described. The programmable graphics processor supports high-precision data formats and can be programmed to complete a plurality of compositing operations in a single pass through a fragment processing pipeline within the programmable graphics processor. Source images for one or more compositing operations are stored in graphics memory, and a resulting composited image is output or stored in graphics memory. More-complex compositing operations, such as blur, warping, morphing, and the like, can be completed in multiple passes through the fragment processing pipeline. A composited image produced during a pass through the fragment processing pipeline is stored in graphics memory and is available as a source image for a subsequent pass.

摘要： A system, method and article of manufacture are provided for interweaving shading calculations and texture retrieval operations during texture sampling in a graphics pipeline. First, a shading calculation is performed in order to generate output. Next, texture information is retrieved, and another shading calculation is performed using the texture information in order to generate additional output. Texture information may be retrieved and shading calculations may then be repeated as desired. Thereafter, the generated output may be combined. As such, the repeated texture information retrieval and shading calculations may be carried out in an iterative, programmable manner.

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.

摘要： Apparatuses and methods for detecting position conflicts during fragment processing are described. Prior to executing a program on a fragment, a conflict detection unit, within a fragment processor checks if there is a position conflict indicating a RAW (read after write) hazard may exist. A RAW hazard exists when there is a pending write to a destination location that source data will be read from during execution of the program. When the fragment enters a processing pipeline, each destination location that may be written during the processing of the fragment is entered in conflict detection unit. During processing, the conflict detection unit is updated when a pending write to a destination location is completed.

摘要： Method and interface for sending vertex data output from a vertex processing unit to memory is described. Conventionally, the vertex data output is not output directly to memory via a dedicated write interface, but is instead passed through downstream computation units in a graphics processor and written to memory via the write interface normally used to write pixel data. When the downstream computation units are configured to pass the vertex data output through unmodified, processing of the vertex data output by the downstream computation units is deferred until a second pass through those units. When the vertex data output is output directly to memory, processing of the vertex data output by the downstream computation units can be initiated during a first pass through those units.
摘要翻译：描述从顶点处理单元向存储器输出顶点数据的方法和接口。通常，顶点数据输出不通过专用写入接口直接输出到存储器，而是通过图形处理器中的下游计算单元传送，并通过通常用于写入像素数据的写入接口写入存储器。当下游计算单元被配置为通过未修改的顶点数据输出传递时，由下游计算单元输出的顶点数据的处理被推迟到第二次通过这些单元。当顶点数据输出被直接输出到存储器时，由下游计算单元输出的顶点数据的处理可以在首次通过这些单元时启动。
