#《UnityAPI.Camera摄像机》发布说明:

++++“UnityAPI.Camera摄像机是对UnityAPICamera类的剖析和拓展

立钻哥哥:Unity是一个入门快、提高难的游戏引擎,想要提升能力,至少需要越过3道坎:API+Shader+综合能力

++1、API的积累:API的合理利用不仅可以减轻自己的编码负担,而且往往可以提高程序的运行效率;这也是钻哥开始“Unity API”独立打造分类的初衷

++2、Shader编程:想要做出一款精品游戏往往需要有高效的Shader的支持;Unity提供了一套改良的“Shader Lab”系统,优化了繁杂的“Open GL”编程

++3、综合能力(技术+业务+管理):一款产品的制作除了功能编程外,往往会涉及很多其他领域,例如产品架构、UI交互设计、模型制作等,作为主要的编程人员,对其他相关领域的了解程序往往会影响到产品制作直至最后的产品体验

++++立钻哥哥一直在推动【VR云游戏=Unity+SteamVR+云技术+5G+AI,这个只是一个引子,抛砖引玉让大家对整个知识体系有一个明确的落地方向,宝宝们可以根据自己的兴趣方向进行拓展:比如Unity这里是指一种“3D游戏引擎”,也可拓展至“UE4Cocos2dx”等游戏引擎;SteamVR是一种跨硬件解决方案,也可拓展至“VRTK”等第三方插件;“云技术+5G”是一种跨平台解决方案的核心技术,同样可拓展至其他平台解决方案;AI也是一种先进技术的举例,也可以拓展至任何一种前沿技术

++++具有较低深度的摄像机将在较高深度的摄像机之前渲染

++++如果有多个摄像机并且其中一些不需要覆盖整个屏幕,可以使用这个来控制摄像机的绘制次序

++++经验总结:场景中的摄像机都会被渲染,由深度0开始依次递增渲染,且摄像机视口画面会依次叠加覆盖,运行后看到的是最后一个摄像机的渲染图

++++每层的消隐距离

++++通常摄像机跳过渲染对象是远于farClipPlane,可以使用layerCullDistances设置某些层使用较小消隐距离,如果把它们放到合适的层级,这对于早期剔除一些小的物体对象是非常有用的

++++当分配layerCullDistances,需要指定的float数组有32个值;0值的消隐距离是使用远剪裁屏幕距离

Camera.OnRenderImage(RenderTexture source, RenderTexture destination);

++++OnRenderImage在所有渲染完成后被调用,来渲染图片的后期处理效果(仅限UnityPro

++++这允许使用基于Shader的过滤器来处理最后的图片,进入的图片时Source渲染纹理,结果是Destination渲染纹理;当有多个图片过滤器附加在摄像机上时,它们序列化的处理图片,将第一个过滤器的目标作为下一个过滤器的源

++++这个消息被发送到所有附加在摄像机上的脚本

using UnityEngine;

using System.Collections

 

public class YanlzCamera : MonoBehaviour{

    public Material mat;

 

    void OnRenderImage(RenderTexture src, RenderTexture dest){

        Graphics.Blit(src, dest, mat);

    }    //立钻哥哥:void OnRenderImage(){}

 

}    //立钻哥哥:public class YanlzCamera{}

++++立钻哥哥:在渲染物体之后

Camera.OnRenderObject();

++++OnRenderObject被用来渲染自己的物体,使用或者其他函数

++++该函数被用来渲染自己的物体,使用Graphics.DrawMeshNow或者其他函数;这个函数类似于OnPostRender,除了OnRenderObject在任意物体有一个脚本带有这个函数被调用,不论是否它附加到摄像机或没有

using UnityEngine;

using System.Collections;

 

public class YanlzCamera : MonoBehaviour{

    public Mesh mainMesh;

    public Mesh miniMapMesh;

 

    void OnRenderObject(){

        if(Camera.current.name == MiniMapcam){

            Graphics.DrawMeshNow(miniMapMesh, transform.position, transform.rotation);

        }else{

            Graphics.DrawMeshNow(mainMesh, transform.position, transform.rotation);

        }

    }    //立钻哥哥:void OnRenderObject(){}

 

}    //立钻哥哥:public class YanlzCamera{}

 

 

 

 

 

++F6.5、OnWillRenderObject

++F6.5、OnWillRenderObject

++F6.5、OnWillRenderObject

++++立钻哥哥:在渲染物体之前

Camera.OnWillRenderObject();

++++如果物体可见,每个摄像机都会调用OnWillRenderObject;

++++如果对象是被视为可见的从当前摄像机消隐过程后,这个函数被调用;该方法是很有用的,如果需要为每一个摄像机准备步骤渲染对象;一个例子是:渲染反射到一个渲染图片,这个反射将会不同于每个摄像机的视窗,且需要被渲染在原来的对象之前;如果对象被一个给定的摄像机剔除,该对象将被跳过反射

++++注意:Camera.current将被设置为要渲染这个物体的相机
