Unity Commandbuffer Learning

Unity's Official tutorial: https://blogs.unity3d.com/cn/2015/02/06/extending-unity-5-rendering-pipeline-command-buffers/

A demo project is included at the bottom of the article

Changed with the official example, as a test script

usingUnityengine;usingunityengine.rendering;usingSystem.Collections;usingSystem.Collections.Generic; Public classtest:monobehaviour{ PublicMesh Testmesh;  PublicMaterial testmaterial; Dictionary<camera, commandbuffer> M_cameras =NewDictionary<camera, commandbuffer>(); voidondisable () {foreach(varCaminchM_cameras) {            if(Cam. Key) {cam. Key.removecommandbuffer (cameraevent.beforelighting, Cam.            Value); }        }    }    voidlateupdate () {varact = gameobject.activeinhierarchy &&enabled; if(!Act)            {ondisable (); return; }        varCam =camera.current; if(!Cam)return; Commandbuffer buf=NULL; if(M_cameras.containskey (CAM)) {buf=M_cameras[cam]; Buf.        Clear (); }        Else{buf=NewCommandbuffer (); Buf.name="Test Command Buffer"; M_cameras[cam]=buf; Cam.        Addcommandbuffer (Cameraevent.afterfinalpass, buf); } buf. DrawMesh (Testmesh, Matrix4x4.trs (Camera.main.transform.position+ Camera.main.transform.forward *4f, Quaternion.identity, Vector3.one), testmaterial); }}

The script is simple and draws a mesh after Finalpass

Commandbuffer supports deferred rendering and forward rendering, but it is important to note that if deferred rendering events such as Cameraevent.aftergbuffer are used in forward rendering, this will not work.

Unity's framedebug can be debugged on Commandbuffer

Be free and perfect
