摘要： An output buffer in a multi-threaded processor is managed to store a variable amount of output data. Parallel threads produce a variable amount of output data. A controller is configured to determine how much output buffer space is needed per thread and how many threads can execute in parallel, given the available space in the output buffer. The controller also determines where each thread writes to in the output buffer.

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： Vertices defining a graphics primitive are converted into homogeneous space and clipped against a single clipping plane, the w=0 plane, to produce a clipped graphics primitive having vertices including w coordinates that are greater than or equal to zero. Rasterizing a graphics primitive having a vertex with a w coordinates that is greater than or equal to zero is less complex than rasterizing a graphics primitive having a vertex with a w coordinate that is less than zero. Clipping against the w=0 plane is less complex than conventional clipping since conventional clipping may require that the graphics primitive be clipped against each of the six faces of the viewing frustum to produce a clipped graphics primitive.
摘要翻译： 定义图形基元的顶点被转换成均匀空间，并且相对于单个剪切平面（w = 0平面）被剪切，以产生具有包括大于或等于零的w坐标的顶点的剪切图形基元。 栅格化具有w坐标大于或等于零的顶点的图形原语比光栅化具有小于零的w坐标的顶点的图形基元复杂化。 针对w = 0平面的剪切不如传统的剪裁那样复杂，因为常规的剪裁可能要求将图形原语对准观察平截头体的六个面中的每一个以产生剪切的图形原语。

摘要： A system and method for tracking and reporting texture map levels of detail that are computed during graphics processing allows for efficient management of texture map storage. Minimum and/or maximum pre-clamped texture map levels of detail values are tracked by a graphics processor and an array stored in memory is updated to report the minimum and/or maximum values for use by an application program. The minimum and/or maximum values may be used to determine the active set of texture map levels of detail that is loaded into graphics memory.
