摘要： A graphics pipeline has at least one stage that determines operations to be performed on graphics data based at least in part on data processing attributes associated with the graphics data. One application is to permit one or more operations in a stage to be bypassed. Another application is a multi-function stage in which the data operations that are performed depend at least in part on the data type.

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： System and method for reserving a memory space for multithreaded processing is described. Memory space within a memory resource is allocated responsive to thread type. Examples of thread types for graphics processing include primitive, vertex and pixel types. Memory space allocated may be of a predetermined size for a thread type. Memory locations within a first memory space may be interleaved with memory locations within a second memory space.

摘要： A graphics data-processing pipeline including a geometry processor and a fragment processor. The graphics data-processing pipeline being configured to render stencil data and to output the stencil data in a format compatible with input to the fragment processor. An output of the graphics data-processing pipeline is written to local memory and the output is subsequently read using the fragment processor without host processor intervening usage to format the stencil data or process the stencil data.

摘要： A graphical processing unit (GPU) and methods for rendering a three-dimensional (3D) scene generated in a field of view having in-focus and out-of-focus regions on a two-dimensional (2D) screen region of pixels are described. One method includes initially rendering the scene to create color and depth texture maps and creating mip-map layers for the color texture map. The method further comprises subsequently rendering the scene by, for each pixel: creating a mip-map layer selection value as a function of a depth of the pixel from the depth texture map, generating a color value by interpolation using color values from at least one of the mip-map layers chosen according to the mip-map layer selection value, and setting a color of the pixel to the generated color texture.

摘要： A system and method are provided for improved shadow mapping in a graphics pipeline. Raw depth values are initially collected from two depth layers in a scene to be rendered. Shadow-map depth values are then calculated utilizing the raw depth values. The scene is then shadow mapped utilizing the shadow-map depth values in order to improve the appearance of shadows in a rendered scene. The various steps are carried out by a hardware-implemented graphics pipeline, which may include texturing or shadowing mapping hardware.
