Methods and apparatuses of planning a wireless local area network are disclosed. Various embodiments receive data such as floor plan data, coverage data, and / or capacity data about a site for the WLAN. Based on such data, features of the WLAN access points can be determined.

A technique for multiresolution consistent rasterization in which a setup unit calculates universal edge equations for a universal resolution. A rasterizer evaluates coverage data for two different resolutions based on the edge equations. The rasterizer evaluates coverage data for different effective pixel sizes—a large pixel size and a small pixel size. Optionally, the rasterizer may determine a first set of coverage data by performing conservative rasterization to determine coverage data for large pixels. Optionally, the rasterizer may then determine a second set of coverage data by performing standard rasterization for small pixels. Optionally, for the second set of coverage data, the rasterizer may evaluate only the small pixels that are within large pixels in the first set of coverage data that evaluate as covered.

The pixel distribution logic selects one of the processing clusters to which the coverage data for a first pixel is delivered based at least in part on a location of the first pixel within an image area. The processing clusters can be mapped directly to the frame buffers partitions without a crossbar so that pixel data is delivered directly from the processing cluster to the appropriate frame buffer partitions. Alternatively, a crossbar coupled to each of the processing clusters is configured to deliver pixel data from the processing clusters to a frame buffer having a plurality of partitions. The crossbar is configured such that pixel data generated by any one of the processing clusters is deliverable to any one of the frame buffer partitions.

Wireless coverage data are associated with a geographic database that contains data that represent a road network in a geographic region. The wireless coverage data indicate areas within the geographic region in which navigation-related services or data from a navigation services provider are available wirelessly, or conversely, areas within the geographic region in which navigation-related services or data from a navigation services provider are not available wirelessly. An end user obtains the wireless coverage data. The wireless coverage data are used to indicate to the end user areas in which navigation-related services or data from the navigation services provider are available wirelessly or areas in which navigation-related services or data from the navigation services provider are not available wirelessly. The wireless coverage data may also be used to warn the end user when he / she is leaving an area in which navigation-related services or data from the navigation services provider are available wirelessly. Data for uncovered areas can be downloaded to an end user's computing platform while the end user is still within an area in which navigation-related data from the navigation services provider are available wirelessly.

An improved mechanism is provided for generating an execution log and coverage data for a set of computer code. To minimize the amount of storage required for storing execution log information, the mechanism: (1) stores only information pertaining to instructions that are actually executed during execution; and (2) stores the information in a hierarchically organized set of lists. In addition, to minimize the impact of execution log and coverage data generation on the execution of the computer code, coverage data is generated after execution has completed. By generating the execution log and coverage data in this manner, storage requirements are reduced, and execution performance is improved.

One embodiment of the present invention sets forth a technique for rendering anti-aliased paths by first generating an alpha buffer representing coverage data. To generate the alpha buffer, jittered versions of the rendered path are rendered and corresponding stencil buffers indicating sub-pixel samples of the path that should be covered are generated. After each stencil buffer is generated, the jittered path is rasterized to convert the sub-pixel coverage into coverage weights that are stored in the alpha component of a frame buffer. As each jittered path is rasterized, the coverage weights are accumulated. Finally, geometry representing the union of the jittered versions of the path is rendered to shade pixels based on the accumulated coverage weights. The anti-aliased rendered paths may be filled or stroked without tessellating the paths.
