摘要： The present invention is directed towards providing a system and method for optimizing HTML output in a just-in-time compiling environment for devices such as mobile devices. A method is provided for optimizing the output in a single pass as device content is rendered. The method delays writing a closing tag until it is determined that a formatting or layout of the next control conflicts. Tags are emitted in a predefined order to minimize the number of tags that will need to be closed to accommodate a following control whose style differs. Object hierarchy is leveraged to predict the order in which tags should be written without looking ahead of the current control in the hierarchy.

摘要： A server-based application includes at least one page file that identifies one or more server objects. The page file describes the particular layout and interaction of the server objects, such as controls, in such a way that a page of information may be transmitted to a target device. When designing the page file a developer may use declarative statement, so that certain properties of the specified controls may be altered based on the particular type of target device.

摘要： A computing system translates two-dimensional (2D) graphical input by a user who is selecting one or more 2D images in a three-dimensional (3D) scene of 3D models created by model 3D objects. The computing system comprises a viewport module, a retrieve module, set ray module and, a hit detection module. The viewport module defines 2D boundaries of the 3D scene and a view point location in 3D space for viewing the 3D scene. The retrieve module retrievies a selection point location in 2D space for the 2D graphical input. The set ray module sets a pick ray in 3D space based on the view point location and the selection point location. The hit detection module detects a hit by the pick ray on a 3D model in the 3D scene. In this computing system there is a method of processing a hierarchy of computer program visual objects for detecting a hit by 2D input on 2D and 3D images displayed by a computing system. The method begins by traversing branches of a first tree hierarchy of visual objects to leaf objects. Next the method detects whether the next unprocessed leaf object is a visual 2D object with 2D geometry or a model 3D object with 3D geometry. Lastly the method calls a 2D process to detect a hit on the 2D geometry of a visual object if a visual 2D object is detected and calls the 3D process to detect a hit on the 3D geometry of a visual object if a model 3D object is detected.
摘要翻译： 计算系统通过在由模型3D对象创建的3D模型的三维（3D）场景中选择一个或多个2D图像的用户来翻译二维（2D）图形输入。 计算系统包括视口模块，检索模块，设置射线模块和命中检测模块。 视口模块定义3D场景的2D边界和用于观看3D场景的3D空间中的视点位置。 检索模块检索2D图形输入的2D空间中的选择点位置。 基于视点位置和选择点位置，设置射线模块在3D空间中设置拾取光线。 命中检测模块检测3D场景中的3D模型上的拾取光线的命中。 在该计算系统中，存在一种处理计算机程序视觉对象的层次结构的方法，用于检测由计算系统显示的2D和3D图像上的2D输入的命中。 该方法通过将可视对象的第一树层次结构的分支遍历到叶对象来开始。 接下来，该方法检测下一个未处理的叶对象是具有2D几何的可视2D对象还是具有3D几何的模型3D对象。 最后，如果检测到视觉2D对象，则该方法调用2D过程来检测视觉对象的2D几何的命中，并且如果检测到模型3D对象，则调用3D处理来检测对视觉对象的3D几何图像的命中 。

摘要： Various technologies and techniques are disclosed that enable interaction with 2D content placed on a 3D surface. The system determines where relative to a 3D surface an input device is located. If the input device is hitting a 3D surface, a hidden content in 2D is positioned so that a point representing the area hit on the 3D surface lines up with a corresponding point on the hidden content in 2D. For example, when a request is received for the input device position when an input device is detected at a location in a scene, the 3D surface is projected into two dimensions. A closest point is calculated on the projected. 3D surface to a 2D location of the input device. The closest point is provided in response to be used in positioning the hidden content with the corresponding point of the 3D surface.

摘要： Space is allocated within a table layout for a plurality of items to be placed therein by application of a first rule in which each item is ordered according to increasing column span for the item. Thereafter, a second rule is applied for each ordered item. The second rule recognizes that space need not necessarily be added to the right-most column for an item at issue, and that space needed for the right-most column for an item at issue should be ‘borrowed’ from the next column to the right, presuming such space is available and would not impinge on any other item. Finally, the second rule recognizes that despite everything, situations can arise where there is no elegant way to allocate space for all items within a table layout. In such a circumstance, space is added to the right-most column for the item at issue.
摘要翻译： 通过应用第一规则，在表布局内为多个项目分配空间，其中根据项目的增加列跨度对每个项目进行排序。 此后，对于每个有序项目应用第二规则。 第二条规则认为，空间不一定必须添加到所讨论的项目的最右边的列中，并且所讨论的项目的最右边列所需的空间应该从右边的下一列“借” ，假设这样的空间是可用的，不会影响任何其他项目。 最后，第二条规则认识到，尽管有一切，但是如果没有优雅的方式为表格布局中的所有项目分配空间，情况就会出现。 在这种情况下，空间会被添加到所讨论项目的最右边的列中。

摘要： Various technologies and techniques are disclosed that improve the automatic generation of near and far clipping planes for a 3D scene. The viewing frustum is intersected with the scene to determine the range of depth that a particular scene occupies in the viewing frustum. The ratio of the near clipping plane to far clipping plane is adjusted as appropriate to ensure a desired minimum level of Z-buffer precision is achieved. The clipping planes are set sufficiently far outside of the object bounds to prevent triangles which are parallel to the clip planes from being accidentally clipped. An API is provided to allow other programs to retrieve the near and far clipping plane values with the desired minimum Z-buffer precision for a particular scene without having to interact with the Z-buffer.
