Unity3D 成神之路

最新高通 Vuforia 7.0.47 版本-对应API-动态加

2018-03-23  本文已影响67人  su9257_海澜

整理了下Vuforia 7 版本对应识别功能的函数 基本上和6版本无差异


Vuforia版本获取

       string vuforiaVersion = Vuforia.VuforiaUnity.GetVuforiaLibraryVersion();
       string unityVersion = UnityEngine.Application.unityVersion;
       UnityEngine.Debug.Log("Vuforia " + vuforiaVersion + "\nUnity " + unityVersion);

控制vuforia摄像机对应的Texture渲染

         VuforiaRenderer.Instance.Pause(true);//关闭渲染 参数false开始渲染

代码块如下
