可见性

Why Do I Need Both Visibility and Control?

为什么我需要可见性和控制？

During preprocessing phase, build a hierarchical decomposition of the environment using an octree and create HLODs. At run time, use multiple threads to render the environment: use visibility culling to cull those invisible blocks, choose HLOD according to screen error, and also use data management and attemperation to update the data in main memory.

预处理阶段利用八叉树构造场景的分层次结构；实时渲染阶段，采用多线程进行场景的实时绘制：根据视点进行可见性剔除，根据屏幕误差选择合理的分级细节层次，利用数据管理调度进行数据的实时更新。

The subscriber's security and the confirmer signature invisibility are characteristic to a confirmer signature scheme.

签名者的安全性和证实签名的&不可见性&是一个证实数字签名方案必须具备的两个重要特性。

The signature subscriber s security and the confirmer signature s invisibility are characteristic to a confirmer signature scheme.

签名者的安全性和证实签名的&不可见性&是一个证实数字签名方案必须具备的两个重要特性。

The key technologies of transformer substation's virtual-reality simulation are studied. A method of organizing the virtual space and objects' models into a hierarchy tree according to their electee relationship is applied.

重点研究了变电站一次设备仿真虚拟场景生成的关键技术，对于大规模复杂场景，给出一种综合了电气连接特性和树型层次结构的虚拟场景模型组织方法，并基于该场景模型组织方法提出了快速可见性预判断和LOD层次预计算的加速绘制方法。

Here,however, the degree of dependence is not related to the level of observability .

不过，不管如何，依赖的程度和信任度与可见性的水准没有关联。

Two new algorithms of structural volume skeletonization and internal visibility computation are presented to support the virtual endoscope system.

提出了包含距离和拓扑信息的结构化骨架提取方法和骨架指导的内窥可见性计算方法，并将其有机地应用于虚拟漫游系统中。

A novel method computing the extended form-factors is given after an extensive examination of existing radiosity, especially the specula radiosity methods.

它可与Z-Buffer硬件加速器或一些可见性预算方法，如BSP方法相结合，大幅度地加快广义形状系数的计算，从而缩短Radiosity场景生成时间。

Whereas software vendors must spend heavily to overcome software's invisibility, superdistribution thrusts software out into the world to serve as its own advertisement.

尽管软件贩卖商必须花费重金来提高软件的可见性，但是超级分发却将软件扔进世界，自己给自己做起了广告。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
