public float fieldOfView ;

描述

摄像机的视野(以度为单位)。

这是垂直视野;水平 视野随视口宽高比的变化而改变,有关更多信息,请参阅 VerticalToHorizontalFieldOfView。 如果是正交摄像机,则忽略视野(请参阅 orthographic)。

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。

如果对 projectionMatrix 进行更改,摄像机将不再根据其 fieldOfView 更新渲染。在调用 ResetProjectionMatrix 之前,该设置持续有效。

//Attach this script to an empty GameObject.
//This script creates a Slider that allows you to manipulate the Camera's field of view. Place GameObjects in the Scene to show the full effect.

using UnityEngine;

public class CameraFieldOfViewExample : MonoBehaviour { //This is the field of view that the Camera has float m_FieldOfView;

void Start() { //Start the Camera field of view at 60 m_FieldOfView = 60.0f; }

void Update() { //Update the camera's field of view to be the variable returning from the Slider Camera.main.fieldOfView = m_FieldOfView; }

void OnGUI() { //Set up the maximum and minimum values the Slider can return (you can change these) float max, min; max = 150.0f; min = 20.0f; //This Slider changes the field of view of the Camera between the minimum and maximum values m_FieldOfView = GUI.HorizontalSlider(new Rect(20, 20, 100, 40), m_FieldOfView, min, max); } }
