The vertical field of view of the Camera, in degrees.
This is the vertical field of view; horizontal field of view depends on the viewport's aspect ratio. For for more information, see VerticalToHorizontalFieldOfView.
If Camera.orthographic is true
, the Camera ignores fieldOfView
.
某些 VR SDK 具有用于 VR 摄像机的固定视野值。使用这些 SDK 启用 VR 时,该属性将始终返回来自 SDK 的值。如果您尝试设置该属性,则会在记录中看到一条警告,并且该值会被忽略。
If you make changes to Camera.projectionMatrix, the Camera ignores fieldOfView
. This lasts until you call Camera.ResetProjectionMatrix.
In the Unity Editor, this corresponds to the Clipping Planes: Near property in the Camera component Inspector.
