摘要： A bracket for reinforcing a wooden joist provided with a hole for the passage of a utility conduit. The bracket includes a base wall having a central opening, sized to accommodate the utility conduit, for positioning against one side of the wooden joist. A pair of integral side walls extend at right angles from the base wall. A pair of integral flanges extend at right angles from the pair of side walls so as to be parallel to the base wall.

摘要： An interactive computer graphics display system processing method for identifying a displayed primitive that intersects an operator selected area of the display screen. Pursuant to the method, the operator selected area of the display screen is reverse mapped to world coordinate space; data representative of displayed geometric primitives is then clipped against the reverse mapped selected area in world coordinate space; and clipped data representative of displayed geometric primitives that intersect the reverse mapped selected area are identified for operator defined application processing. Further processing steps include mapping of the identified data to screen coordinate space and rasterization of the data for display in the screen monitor. A zoom processing method is also provided wherein an original operator defined zoom window is transformed from screen coordinate space to world coordinate space and the boundaries of the transformed window in world coordinate space are utilized as data clipping boundaries. After clipping, data representative of a displayed geometric primitive outside the inverse mapped zoom window is discarded, thus preventing the rerasterization of geometric primitives outside the zoom window. Further processing includes mapping of the identified data to a defined zoom window in screen coordinate space for operator viewing and selection of a particular geometric primitive for application processing.

摘要： A method for clipping two and three dimensional graphic primitives for use in a computer graphics workstation. During the first clipping stage, the system removes all graphic primitives which lie outside an arbitrary clipping volume or window that is an enlargement of the desired viewing volume or window. This clipping volume (window) is then projected and mapped onto a virtual viewport which is larger than the real viewport. After this mapping occurs, rendering effects (such as line styles, line width, pattern fill, hatch fill, etc.) are applied to the primitive. A subsequent stage of clipping is then applied to clip the virtual viewport to the real viewport which is the user's visible area. Use of the clipping volume (window) during the first stage of clipping makes it simpler to transform geometric primitives which are partially visible to the viewer, and gives visible primitives a richer set of invariant geometric properties so that their rendering effects may be more easily and correctly carried out.
摘要翻译：一种用于裁剪用于计算机图形工作站的二维和三维图形图元的方法。在第一个剪辑阶段，系统将删除位于任意裁剪卷或窗口之外的所有图形原语，这些缩放卷或窗口是所需观看卷或窗口的放大图。然后将该剪辑卷（窗口）投影并映射到大于真实视口的虚拟视口。发生这种映射之后，将渲染效果（如线条样式，线宽，图案填充，填充填充等）应用于原语。然后应用后续的剪辑阶段将虚拟视口剪切到作为用户可见区域的真实视口。在剪辑的第一阶段使用剪辑卷（窗口）使得更容易地对观看者部分可见的几何图元进行变换，并且给予可见原始图形更丰富的不变几何属性集，使得它们的渲染效果可以更容易地正确进行
