快速实时GI环境光 快速实时GI环境光可以用天空盒直接驱动环境光输入。这在环境光每帧都会发生变化的情况下非常不理想。所以替代方法是,由当前时间来控制环境光,并转换为关照渐变和环境光强度用于驱动实时GI系统。这些都可以在光照面板中设置:
更新环境光代码如下:
using System;
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
[ExecuteInEditMode]
public class EnvironmentUpdater : MonoBehaviour {
public Gradient groundGradient, equatorGradient, skyGradient;
private TimeOfDayManager m_TimeOfDayManager;
void OnEnable () {
m_TimeOfDayManager = FindObjectOfType<timeofdaymanager> ();
}
void Update () {
float currentTime = m_TimeOfDayManager.time;
RenderSettings.ambientGroundColor = groundGradient.Evaluate(currentTime);
RenderSettings.ambientEquatorColor = equatorGradient.Evaluate(currentTime);
RenderSettings.ambientSkyColor = skyGradient.Evaluate(currentTime);
}
}
