摘要： Method and apparatus for display image adjustment is described. More particularly, handles associated with polygon vertices of a polygon rendered image are provided as a graphical user interface (GUI). These handles may be selected and moved by a user with a cursor pointing device to adjust a displayed image for keystoning, among other types of distortion. This GUI allows a user to adjust a projected image for position of a projector with respect to imaging surface, as well as for imaging surface contour, where such contour may be at least substantially planar, cylindrical, or spherical and where such contour may comprise multiple imaging surfaces. This advantageously may be done without special optics or special equipment. An original image is used as texture for rendering polygons, where the image is applied to the rendered polygons.

摘要： One embodiment of the present invention sets forth a technique for transmitting state information associated with at least one graphics command to a graphics processor. The method includes the steps of generating a state object that specifies a set of properties that is needed to execute a first graphics command within the graphics processor, storing in the state object a value associated with a first property included in the set of properties, marking a second property included in the set of properties as a dynamic property, where a value associated with the second property is not stored in the state object and can be updated without having to modify the state object, and transmitting the state object to the graphics processor in order to execute the first graphics command

摘要： One embodiment of the present invention sets forth a technique for reducing overhead associated with transmitting primitive draw commands from memory to a graphics processing unit (GPU). Command pairs comprising an end draw command and a begin draw command associated with a conventional graphics application programming interface (API) are selectively replaced with a new construct. The new construct is a reset topology index, which implements a combined function of the end draw command and begin draw command. The new construct improves efficiency by reducing total data transmitted from memory to the GPU.

摘要： One embodiment of the present invention sets forth a technique for configuring a graphics processing pipeline (GPP) to process data according to one or more shader programs. The method includes receiving a plurality of pointers, where each pointer references a different shader program header (SPH) included in a plurality of SPHs, and each SPH is associated with a different shader program that executes within the GPP. For each SPH included in the plurality of SPHs, one or more GPP configuration parameters included in the SPH are identified, and the GPP is adjusted based on the one or more GPP configuration parameters.

摘要： A technique for handling floating-point special values, e.g., Infinity, NaN, −Zero, and denorms, during blend operations is provided so that blend operations on fragment color values that contain special values can be performed in compliance with special value handling rules. In particular, the presence of special values is detected or the potential presence of special values is detected. This information is used to qualify when blend optimizations may be performed, so that floating point blend operations can remain conformant to special value handling rules.

摘要： A method and system for overriding state information programmed into a processor using an application programming interface (API) avoids introducing error conditions in the processor. An override monitor unit within the processor stores the programmed state for any setting that is overridden so that the programmed state can be restored when the error condition no longer exists. The override monitor unit overrides the programmed state by forcing the setting to a legal value that does not cause an error condition. The processor is able to continue operating without notifying a device driver that an error condition has occurred since the error condition is avoided.

摘要： The present invention provides post tile sorting setup in a tiled graphics pipeline architecture. In particular, the present invention determines a set of clipping points that identify intersections of a primitive with a tile. The mid-pipeline setup unit is adapted to compute a minimum depth value for that part of the primitive intersecting the tile. The mid-pipeline setup unit can be adapted to process primitives with x-coordinates that are screen based and y-coordinates that are tile based. Additionally, to the mid-pipeline setup unit is adapted to represent both line segments and triangles as quadrilaterals, wherein not all of a quadrilateral's vertices are required to describe a triangle.

摘要： A deferred graphics pipeline processor comprising a texture unit and a texture memory associated with the texture unit. The texture unit applies texture maps stored in the texture memory, to pixel fragments. The textures are MIP-mapped and comprise a series of texture maps at different levels of detail, each map representing the appearance of the texture at a given distance from an eye point. The texture unit performs tri-linear interpolation from the texture maps to produce a texture value for a given pixel fragment that approximates the correct level of detail. The texture memory has texture data stored and accessed in a manner which reduces memory access conflicts and thus improves throughput of said texture unit.

摘要： A data shifting capability that permits sorting the data in addition to searching for obtaining real-time performance in color, with high quality imagery through a simple search of a spacial database based on a rectangularly shaped search region or range search. A sorting Magnitude Comparison Content Addressable Memory (SMCCAM) performs a range search, introducing a conservative approximation of the idea Occluding Region, and provides a MCCAM wherein the data words stored in the fields are shifted to corresponding fields in an adjacent word, based on the magnitude comparisons. The 3D graphics method stores the parameters of a polygon span in a spatial database and a query operation is performed on the database to determine which of those spans, or portions of spans, are visible, and applies a rule for comparing a new span portion to an old span portion on a subspan-by-subspan basis, thereby providing additional polygon edge information within a raster line, providing anti-aliasing.
