    • The level of detail selected for each object in a scene is determined based upon a variable normalized risk parameter which may be supplied by the application. A recursive composite parent object process is invoked upon the two children of the scene object in order to allocate graphics resources to objects A and B. Primary and secondary hit value means corresponding to objects A and B are computed. The hit value means are the average sum of hit values recorded for all the leaf objects contained by the objects over a predetermined number of frames. The statistical variances of the primary hit value and secondary hit value are also computed over the previous predetermined number of frames in order facilitates the mapping of the normalized risk parameter to a non-normalized risk parameter indicating the optimal risk for objects A and object B. A quadratic parametric variance equation is solved for the optimal fraction of the remaining graphics resources to be allocated to object A. The optimal fraction is multiplied by the available graphics resources, resulting in the resources allocated to object A; the remaining graphics resources are to object B. If either object A or B is a leaf object, the level of detail is selected for object A or B as the level of detail associated with object A or B requiring the greatest amount of graphics resources not exceeding the resources allocated to object A or B. If either object A or B is a composite parent object, the recursive parent object process is invoked on the two children of object A or B with the available graphics resources for the instantiation of the recursive parent object process set to the graphics resources allocated to object A or B. After levels of detail for all objects in the scene has been achieved, the method according to the present invention renders all leaf objects.
    • 基于可由应用程序提供的可变归一化风险参数来确定为场景中的每个对象选择的细节级别。 在场景对象的两个子节点上调用递归复合父对象进程,以便将图形资源分配给对象A和B.主要和次要命中值意味着对应于对象A和B的对象。 命中值意味着在预定数量的帧上由对象包含的所有叶对象记录的命中值的平均和。 主要命中值和次要命中值的统计方差也在先前预定数量的帧上计算,以便于将归一化风险参数映射到指示对象A和对象B的最佳风险的非归一化风险参数。 对于要分配给对象A的剩余图形资源的最优分数,求解二次参数方差方程。最佳分数乘以可用图形资源,导致分配给对象A的资源; 剩余的图形资源是对象B.如果任一对象A或B是叶对象,则为对象A或B选择细节级别作为与需要最大量图形资源的对象A或B相关联的细节级别 超过分配给对象A或B的资源。如果任一对象A或B是复合父对象,则对象A或B的两个子节点使用可用的图形资源调用递归父对象进程,以便实现递归父项 对象处理设置为分配给对象A或B的图形资源。在场景中的所有对象的细节级别已经实现之后,根据本发明的方法呈现所有叶对象。

    • In one example, a method includes determining, by a computing device, a plurality of features. Each feature from the plurality of features may be usable to determine a dominant hand of a user of the computing device. The method also includes receiving, by the computing device, a plurality of input values, each input value from the plurality of input values corresponding to the respective plurality of features, and determining, using a probabilistic model and based at least in part on at least one input value from the plurality of input values corresponding to the respective feature from the plurality of features, a hand of the user as a dominant hand of the user. The method also includes generating, based at least in part on the determined dominant hand of the user, a graphical user interface for display at a presence-sensitive display operatively coupled to the computing device.
