MonoBehaviour.OnPreCull()

Descripción

OnPreCull is called before a camera culls the scene.

Culling determines which objects are visible to the camera. OnPreCull is called just before this process.

Esta función se llama solamente si el script está adjunto a la cámara y está habilitado.

If you want to change camera's viewing parameters (e.g. fieldOfView or just transform), this is the place to do it. Visibility of scene objects will be determined based on camera's parameters after OnPreCull.

// Attach this to a camera.
// Inverts the view of the camera so everything rendered by it, is flipped
