IG主机

To run IG Host with your IG application, copy the ig_host binaries from the demos/cigi_demo/bin/ folder to your project:要将IG Host与IG应用程序一起运行，请将ig_host二进制文件从demos/cigi_demo/bin/文件夹复制到您的项目中：

• For Windows — ig_host_x64.pdb, ig_host_x64.exe, ig_host_x64d.exe对于Windows-ig_host_x64.pdb, ig_host_x64.exe, ig_host_x64d.exe
• For Linux — ig_host_x64, ig_host_x64d对于Linux-ig_host_x64, ig_host_x64d

In the IG Host window, open the Settings window (File -> Settings) and set the following parameters:在IG Host窗口中，打开Settings窗口（File -> Settings）并设置以下参数：

• Async Mode currently should be disabled.当前应禁用Async Mode。
• Geodetic Origin — the coordinates that are set for the Geodetic Pivot in the world you have created.Geodetic Origin-在您创建的世界中为Geodetic Pivot设置的坐标。
• Spawn Point — the coordinates of the entity spawn location.Spawn Point —实体产生位置的坐标。
• CIGIConnector settings, if necessary.CIGIConnector设置（如有必要）。

To have an environment displayed in IG, you need to load a world (database).要在IG中显示环境，您需要加载一个世界（数据库）。

1. Open the Database List window (Windows -> Database List).打开Database List窗口（Windows -> Database List）。
2. Select a database from the list.从列表中选择一个数据库。
3. Click Load.点击Load。
4. Check if the world has been loaded in the IG window. Click Connect/Reconnect in the Settings window, if necessary.在IG窗口中检查世界是否已加载。如有必要，请在Settings窗口中单击Connect/Reconnect。

You can add more databases to the list. The databases you want to add should be located inside the /data folder of the project you work with. To add another world to the database list:您可以将更多数据库添加到列表中。您要添加的数据库应位于您使用的项目的/data文件夹内。要将另一个世界添加到数据库列表中：

1. Click Add.点击Add。
2. Select the *.world file to be loaded.选择要加载的*.world文件。
3. Specify the latitude and longitude of the geodetic pivot in that world.指定该世界中大地坐标的纬度和经度。
4. Click OK.点击OK。
5. Reopen IG and IG Host.重新打开IG和IG Host。

The entity is added as follows:实体添加如下：

1. Open the Entity List window (Windows -> Entity List).打开Entity List窗口（Windows -> Entity List）。
2. Double-click an entity from the list to open Entity Properties.从列表中双击一个实体以打开Entity Properties。
3. Set the entity Type, and check its position (most importantly along the Z axis to make sure it is not under the ground).设置实体类型，并检查其位置（最重要的是沿Z轴以确保其不在地下）。
4. Set other parameters, if necessary.如有必要，设置其他参数。

The view defines what actually is going to be displayed in IG.该视图定义了将在IG中实际显示的内容。

注意

Currently only one view (view 0) is available.当前只有一个视图(view 0)可用。

To open the view settings:要打开视图设置：

1. Open the Views list (Windows -> Views List).打开Views列表（Windows -> Views List）。
2. Double-click a view from the list to open its properties.从列表中双击一个视图以打开其属性。
3. Use Position and Rotation to adjust the camera relative to the entity. Both positive and negative values can be used.使用Position和Rotation相对于实体调整摄影机。正值和负值均可使用。
4. Parent Entity ID — ID of the entity to which camera is attached. By changing this ID, you can switch between entities.Parent Entity ID —摄像机所连接的实体的ID。通过更改此ID，您可以在实体之间切换。

To move the entity around in IG:要在IG中移动实体，请执行以下操作：

1. Select the entity in the Entity List.在Entity List中选择实体。
2. Open the EntityControl window (Windows -> Entity Control).打开EntityControl窗口（Windows -> Entity Control）。
3. Activate the Enabled option.激活Enabled选项。
4. Click in the black area within the IG Host window.单击“ IG Host”窗口中的黑色区域。
5. Use WASDQE buttons and mouse movements to control the entity. Speed is controlled by using Shift + Mouse Scroll button.使用WASDQE按钮和鼠标移动来控制实体。使用Shift + Mouse Scroll按钮控制速度。

There are three Motion Types available:
共有三个Motion Types可用：

• Spectator — camera follows the entity.Spectator-摄影机跟随实体。
• Airplane — the entity moves with a predefined speed, the direction is controlled by the mouse movements.Airplane-实体以预定义的速度移动，方向由鼠标移动控制。
• Circle — entity moves circle-wise using the entered Radius and Circle Center coordinates.Circle-实体使用输入的Radius和Circle Center坐标沿圆周方向移动。

Only one entity can be controlled at a certain moment, switching to another entity stops the movement of the previous entity.
在某个时刻只能控制一个实体，切换到另一个实体将停止前一个实体的移动。

To control the weather, open the Global Weather window (Windows -> Global Weather):要控制天气，请打开Global Weather窗口（Windows -> Global Weather）：

Currently the weather settings are the same as in HEMU.当前的天气设置与中的相同HEMU。

注意

Cumulonimbus clouds (Cumulonimbus 1, Cumulonimbus 2, Cumulonimbus 3) cannot be controlled by the Coverage parameter due to their specific features — this type of clouds always has finite bounds and cannot be global.积雨云（Cumulonimbus 1，Cumulonimbus 2，Cumulonimbus 3）由于其特定功能而无法通过Coverage参数进行控制-这种类型的云始终具有有限的边界并且不能是全局的。

In the File menu, the Save and Load options are available. You can save all IG Host settings and load them as needed.在File菜单中，可以使用Save和Load选项。您可以保存所有IG Host设置并根据需要加载它们。
