General

常规

The LOD object can affect the depiction of objects in accordance with various criteria (e.g., camera distance). This can, for example, be the depiction as a bounding box or with most polygons hidden. Simpler objects can also be substituted for more complex objects. Several options are available.

LOD 对象可以根据各种标准(例如，摄像机距离)影响对象的描绘。例如，可以将其描述为一个边界框，或者将大多数多边形隐藏起来。更简单的对象也可以替代更复杂的对象。有几种选择可供选择。

Scenes can be very complex with regard to the number of objects and detail. It’s very rare that a camera will be able to depict all of a scene’s details, either because they are simply not within the field of view or the objects are so far away that the details can’t be seen. The LOD object can be used to display objects that meet certain requirements only be displayed or rendered in reduced quality.

场景对于物体的数量和细节来说是非常复杂的。一台相机能够描绘出一个场景的所有细节是非常罕见的，要么是因为它们根本不在视野范围之内，要么是因为物体太远以至于细节看不见。LOD 对象可用于显示仅以低质量显示或呈现的符合某些要求的对象。

Generally speaking, the LOD object can help speed up workflow, whether it’s in the Viewport or for rendering. Or an overloaded scene can simply be made more manageable. The LOD object offers numerous options that are described in this section.

一般来说，LOD 对象可以帮助加速工作流，无论是在 Viewport 中还是在呈现中。或者一个超载的场景可以简单地变得更易于管理。LOD 对象提供了许多选项，这些选项在本节中进行了描述。

Use

使用

If an object should be affected by an LOD object, it should be mad a Child object of that LOD object. If, for example, objects that are cloned by the Cloner object should adhere to the LOD object’s settings, make the Cloner object a Child object of the LOD object. The current LOD level for the selected LOD object will be displayed in the Viewport (if it was defined as the render view) HUD.

如果一个对象应该受到 LOD 对象的影响，那么它应该是该 LOD 对象的子对象。例如，如果 Cloner 对象所克隆的对象应该遵循 LOD 对象的设置，则将 Cloner 对象设置为 LOD 对象的子对象。所选 LOD 对象的当前 LOD 级别将显示在 Viewport (如果它被定义为渲染视图) HUD 中。

Tip: 提示:
The global LOD function ( 全局 LOD 函数(Level of Detail 细节层次) can be implemented independently of the LOD object. )可以独立于 LOD 对象实现

The LOD settings only affect the display in the Viewport by default. Rendering always takes place in full detail. This can, however, be changed to render a reduced version of the scene.

默认情况下，LOD 设置只影响 Viewport 的显示效果。渲染总是在完整的细节中进行。然而，这可以改变为渲染场景的缩小版本。

Tip: 提示:
Note that most of the 请注意，大多数Object 对象 tab’s settings are not supported by the Take System (i.e., can’t be overwritten in Takes). 选项卡的设置不被采集系统支持(即，不能在采集中覆盖) Tip 2.: 小贴士2:
Workflow is not sped up in all cases: The substitution or omission of objects can also take time. Depending on the scene and the hardware being used, LOD can also produce a slower workflow. 工作流并非在所有情况下都能加速: 对象的替换或省略也需要时间。根据场景和所使用的硬件，LOD 还可以产生一个较慢的工作流
