1， 安装VIVE_SRanipalInstaller_1.0.3.0
/download/moonlightpeng/11237948
官方的下载地址
/resources/?site=cn
/resources/downloads/?site=cn
2，在unity工程中导入相应的package
Vive-SRanipal-Unity-Plugin.unitypackage
/download/moonlightpeng/11237918
3, 标定
方案1 在没有运行工程时，直接在头盔中通过手柄来标定。
方案2 用unitypackage里面的标定功能。
4， 在工程中用红色的小球表示眼睛的注视点，把自动的紫色的射线不显示。
直接把Line Renderer不要勾选。
5 修改对应的脚本 SRanipal_GazeRaySample.cs
