LOD 检测限Basic 基础Coord.Object 对象Options 选择

Object Properties

对象属性

LOD Mode

检测限模式

These options define how LOD works (Criteria defines when it works), e.g., should objects be substituted or displayed as Null objects?

这些选项定义 LOD 如何工作(Criteria 定义何时工作) ，例如，对象应该被替换或显示为 Null 对象吗？

Each LOD mode has display properties that can be defined separately:

每个 LOD 模式都有可以单独定义的显示属性:

Here you will find the display settings and options that should be familiar from the Display tag. If an object has a Display tag assigned to it, this tag will be overridden by the LOD object’s settings. If Global Shading or Global Style are used, the Viewport or Display tag settings will be used.

在这里，您将找到显示设置和选项，应该是熟悉的显示标记。如果一个对象有一个分配给它的 Display 标记，这个标记将被 LOD 对象的设置覆盖。如果使用全局阴影或全局样式，将使用 Viewport 或 Display 标记设置。

The following options are available for the LOD Mode:

检测限模式有以下选项:

Children

孩子们

In this mode, Child objects will be displayed or hidden in accordance with the Criteria defined. The LOD level number is derived from the number of Children.

在这种模式下，子对象将按照定义的条件显示或隐藏。检测限级别编号是根据子级数目计算出来的。

Arrange the objects to be substituted directly over one another. The object resolution should be arranged increasingly from top to bottom in the Object Manager.

将物体直接置换在另一个物体上。对象解析应该在对象管理器中从上到下逐渐安排。

Manual Groups

人工分组

This mode will display or hide a user-defined number of LOD levels in accordance with the defined Criterium. Further down in the dialog, a sub-tab will be displayed for each LOD level in which you can define objects that should be displayed in the respective level.

此模式将根据定义的 Criterium 显示或隐藏用户定义的 LOD 级别数。在对话框的下方，每个 LOD 级别都会显示一个子选项卡，您可以在其中定义应在相应级别中显示的对象。

Objekte

Objects can be dragged into this field that will be displayed or hidden, depending on the settings defined. Object hierarchies will be included if the hierarchy icon at the far right is enabled.

可以将对象拖动到将显示或隐藏的字段中，具体取决于定义的设置。如果启用了最右边的层次结构图标，则将包括对象层次结构。

Simplify

简化

You can select from the following modes:

你可以从以下模式中选择:

Per Object

每件物品

For the modes Convex Hull or Bounding Box, this option defines, for example, if all Child objects of an LOD object should have a common bounding box (option disabled) or each an individual bounding box (option enabled).

对于凸壳或边界框模式，此选项定义，例如，如果一个 LOD 对象的所有子对象应该有一个公共边界框(禁用选项)或每个单独的边界框(启用选项)。

Criteria

准则

This setting defines which properties should be used to fulfill the measures defined by the LOD Mode. The following criteria are available:

此设置定义应使用哪些属性来实现 LOD 模式定义的度量值。下列准则可供参考:

User LOD Level

用户检测限级别

Here you can "manually" define, which LOD level should be used. This mode is well-suited for testing or defining LOD levels via the Take Manager.

在这里，您可以“手动”定义应该使用哪个 LOD 级别。此模式非常适合通过采取管理器测试或定义 LOD 级别。

User LOD Value

用户检测限值

If this option is enabled, the indicator (the black arrow under the LOD bar) can be used to manually change the LOD value (which can also be displayed by clicking on the small black arrow at the left of the LOD bar).

如启用此选项，可使用指示器(检测限条下的黑色箭头)手动更改检测限值(亦可点击检测限条左边的小黑色箭头)。

Normally, this LOD value will be linked with a property defined in the Criteria mode (e.g., Camera Distance and will be calculated automatically.

通常，这个 LOD 值将与 Criteria 模式中定义的属性(例如，Camera Distance)链接，并自动计算。

The current LOD value is represented by the black arrow (can be moved manually) or a small circle (automatically calculated) below the LOD bar

当前的 LOD 值用黑色箭头(可以手动移动)或 LOD 条下面的小圆(自动计算)表示

A value of 100% normally represents a region with maximum details (the object is the largest or nearest the camera in the Viewport).

值100% 通常表示具有最大细节的区域(对象是 Viewport 中最大或最接近相机的区域)。

Screen Size H
Screen Size V

屏幕尺寸 HScreen 尺寸 v

In the perspective view (when the LOD object is selected in accordance with the colors defined in the LOD bar), a bounding box will be placed over all of the LOD object’s Child objects. Then a ratio of the horizontal/vertical bounding box size to the horizontal/vertical screen size will be generated in order to calculate an LOD value.

在透视视图中(当 LOD 对象根据 LOD 条中定义的颜色选择时) ，将在 LOD 对象的所有 Child 对象上放置一个包围框。然后生成水平/垂直包围盒大小与水平/垂直屏幕大小的比率，以便计算 LOD 值。

For example, if you zoom into an object, the LOD value will change accordingly.

例如，如果放大某个对象，LOD 值将相应地更改。

Screen Surface

屏幕表面

A bounding box will be created here as well - as described above. The LOD value is generated based on the ration of bounding box to screen surface.

这里也将创建一个包围盒——如上所述。根据包围盒与屏幕表面的比值生成 LOD 值。

This means that the larger an object is in the image, the higher its resolution can be and if it’s far away at the horizon it can be represented by a Null object.

这意味着图像中的一个物体越大，它的分辨率就越高，如果它远在地平线上，就可以用一个 Null 物体来表示。

Camera Distance

相机距离

This mode uses the camera’s distance from the LOD object’s origin to ascertain an LOD value in consideration of the Min Dist and Max Dist settings. The camera distance is displayed in the view’s HUD.

这个模式使用摄像机与 LOD 对象原点的距离来确定 LOD 值，并考虑到最小距离和最大距离设置。相机的距离显示在视图的平视显示器。

Global

全球

This setting defines the LOD value using the Level of Detail settings (which can also be defined unter Viewport: Options|Level of Detail).

此设置使用“细节级别”设置(也可以在“ Viewport: Options | Level of Detail”中定义)定义 LOD 值。

Min Dist[0..+∞m]
Max Dist[0..+∞m]

Min Dist [0. . + ∞ m ] Max Dist [0. . + ∞ m ]

These values can be used to define the left and right borders of the LOD. The corresponding LOD level will take effect, depending on the camera’s distance from the LOD object (camera icon under the bar).

这些值可用于定义 LOD 的左边框和右边框。相应的 LOD 级别将生效，具体取决于摄像机与 LOD 对象的距离(酒吧下方的摄像机图标)。

You can also click and drag the camera icon temporarily in order to make the effect visible in the Viewport. This makes it possible to more precisely position the handles.

您还可以单击并暂时拖动相机图标，以便使效果在视窗中可见。这样就可以更精确地定位手柄。

Current Level

现时水平

Here you can define which LOD level should be active. This option is enabled if Criterium is set to LOD Level Custom.

在这里，您可以定义哪个 LOD 级别应该是活动的。如果 Criterium 设置为 LOD 级别自定义，则启用此选项。

Level Count[1..2147483647]

级数[1. . 2147483647]

Here you can manually define an LOD level count. Normally, this count will be set automatically (the setting will then be grayed out) or can be defined interactively using the LOD bar.

在这里，您可以手动定义 LOD 级别计数。通常，这个计数会被自动设置(设置然后会变成灰色) ，或者可以使用 LOD 工具条交互地定义。

LOD Bar

The LOD Bar displays the relation between LOD value and LOD level. The lOD levels are numbered. The corresponding LOD level will be displayed in the Viewport in accordance with how high the LOD value is. The LOD levels are separated by handles that you can slide with the mouse.

LOD 条显示 LOD 值与 LOD 级别之间的关系。检测限水平已编号。Viewport 会根据检测限值的高低，显示相应的检测限值。LOD 级别由可用鼠标滑动的句柄分隔。

In doing so you can press:

这样你可以按:

If you click directly on the bar, the nearest handle (which was previously selected) will be set to the position at which you clicked. You can also double-click on a handle to enter a value directly.

如果您直接单击该栏，最近的句柄(此前已选定)将设置为您单击的位置。还可以双击句柄直接输入值。

Handles can be created by clicking just below the colored LOD levels or by Cmd/Ctrl+clicking on the numbered strip. Handles can be deleted by dragging them away from the bar or selecting them and pressing Del.

可以通过单击彩色 LOD 级别的下方或通过 Cmd/Ctrl + 单击编号条来创建句柄。句柄可以删除拖动他们远离酒吧或选择他们和按 del. 。

If you right-click on the LOD Bar, a menu will open with the following options:

如果你右键单击 LOD 条，菜单将打开以下选项:

The color of LOD levels can be modified. To do so, click on the small arrow at the left of the LOD Bar to open the corresponding menu.

可以修改 LOD 级别的颜色。要做到这一点，请单击 LOD 工具栏左侧的小箭头，打开相应的菜单。

The LOD Value can be modified manually if the respective Criteria option is selected (otherwise it will be grayed out). The Selected Value setting lets you manually define the numeric value of a selected handle.

如果选择了相应的 Criteria 选项，可以手动修改 LOD 值(否则将显示为灰色)。“选定值”设置允许您手动定义选定句柄的数值。

The Color Mode offers the following options:

色彩模式提供以下选项:
