Embodiment Construction

[0010] To aid in understanding the description herein, definitions of certain terms are provided. Primitives can be, for example, points, lines, or triangles. Triangles can be rendered as sets of fans, bars or grids. An object is one or more primitives. A scene is a collection of models and the environment in which they are positioned. A pixel includes information about a position on the screen, as well as color information, and optionally additional information (eg, depth). The color information may be in the form of RGB color triplets. A screen grid cell is the area of ​​the screen that can be occupied by a given pixel. A screen value is a value corresponding to a screen cell or pixel. An Application Programming Interface (API) is the interface between (on the one hand) application programs and (on the other hand) the operating system, hardware and other functionality. The API allows drivers and programs to be created on a variety of platforms, where those drivers and ...

Abstract

A method and apparatus for determining a degree of deflection in a breast compression plate. The mammography apparatus further includes an optical measuring device. The method and apparatus involve (a) providing a pattern on the breast compression plate, the pattern being imagable by the optical measuring device, and having a plurality of local pattern indicia; (b) adjusting the breast compression plate to a selected height; (c) imaging the breast compression plate using the optical measuring device to provide an image of the pattern, the image having a plurality of local image indicia including an associated local image indicia for each local pattern indicia in the plurality of local pattern indicia; and (d) for each local pattern indicia in the plurality of local pattern indicia, determining an associated local deflection of the breast compression plate from the associated local image indicia.

Description

technical field [0001] The present invention relates to application-level control of hardware functionality in embedded devices. The hardware functionality relates to antialiasing of three-dimensional (3D) images processed by a 3D graphics pipeline with such devices. In certain aspects, the invention relates to mobile phones having such hardware functionality. Background technique [0002] Many types of embedded devices have 3D graphics pipelines that process images of 3D scenes. A given scene consists of a collection of rendering objects (eg, triangles). Such 3D pipelines perform anti-aliasing on images. Anti-aliasing involves first oversampling the image, resulting in an increase in the amount of information represented by a now more generous set of (oversampled) pixels. The Quincunx scheme, Full-Scene Antialiasing (FSAA), accumulation buffer, and Carpenter's A-buffer (sometimes called multisampling) are used for Several examples of techniques to implement anti-aliasi...
