摘要： Vertices defining a graphics primitive may be processed in homogeneous space and projected into normalized device coordinate space by dividing each coordinate of a vertex by w. When the w coordinate for a vertex is equal to zero, the projected coordinates are set equal to the homogeneous coordinate values. During a viewport transform operation, only the viewport scale is applied rather than applying the viewport scale and viewport bias to produce the vertex in device coordinate space (screen space). Furthermore, when an edge slope is computed for a vertex with a w coordinate equal to zero, the slope is set equal to the vertex in device coordinate space rather than the difference of the two vertices defining the edge. Therefore, a vertex at infinity is correctly positioned avoiding the introduction of visual artifacts.

摘要： Systems and methods for shaping a shared edge between two or more N-patches may be used to eliminate gaps when normal vectors along a shared edge are not equal. More particularly, vertices and normals of a polygon, tristip, quadstrip and so on, are obtained. Shared vertices corresponding to the shared edge are identified. When normal vectors at a shared vertex are determined to differ, tangents of the normal vectors are computed. These tangents may be used to optionally shape the shared edge, along with control points.

摘要： A system, method and article of manufacture are provided for decomposing surfaces for rendering purposes during computer graphics processing. Initially, an interior mesh of primitives is defined in a surface to be rendered. Next, a plurality of surrounding meshes is defined along sides of the interior mesh. The exterior sides of the surrounding meshes each include a plurality of equally sized segments and at least one fractional segment that is a fraction of the equally sized segments. With this configuration, a pattern of triangles is used that permits the number of triangles to be varied continuously from frame to frame while accommodating incremental evaluation techniques such as forward differencing without visual artifacts such as popping.

摘要： A mechanism and method for recording stereo video with standard camera system electronics and a uniquely adapted optical assembly is disclosed. The optical assembly comprises left and right optical channels disposed to capture and project separate left and right images onto a single image sensor such that the boundary between the projected images is sharply delineated with no substantial overlap or gap. The viewpoints of the left and right optical channels are separated by a distance, d, such that the captured images are differentiated to produce a stereo image pair. By proper disposition of the left and right optical channels, stereo image pairs exhibiting full stereo overlap without keystone distortion are obtained. One image of the stereo pair is produced for visualization by the left eye and the other image is produced for visualization by the right eye. Alternatively, the images can be interrogated by a computer system for generating three dimensional position data. The image sensor is scanned in a standard fashion such that the left and right images are sampled by the video sampling circuitry of the camera unit at substantially the same time. In one mode, a pair of anamorphic lenses compress the left and right images along the axis of the image sensor scan lines so that each video field represents a stereo pair of images at a substantially unity anamorphic ratio and at an aspect ratio substantially equal to that of the image sensor. In a another mode, a conventional (non-distorting) lens is utilized and each video frame represents a pair of images having an aspect ratio equal to one-half that of the image sensor. A stereo playback mechanism and method is also disclosed.

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.

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： 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.
