6.2 IPlane5
主要用来控制相机（三维场景观察点）的坐标位置、角度、速度等参数；提供实现飞行定位和浏览缩放的操作方法；
|
Speed |
设置飞行速度，可用GetSpeed方法来获取速度； |
|
FieldOfView |
相机视域范围； |
|
FlyTo |
飞行到某一位置； |
|
SetPosition |
设置跳转到视角的位置； |
|
MovePosition |
设置移动到视角的位置； |
|
GetPosition |
获取当前视角的位置； |
|
FlyToObject |
飞行到某一对象； |
|
SetSpeed |
设置相机速度； |
|
GetSpeed |
获取相机的速度； |
|
Zoom |
缩放操作； |
|
GetPositionEx |
获取相机的位置和方向； |
