SteamVR插件 要求Unity 4.7.1 或更高版本。 ATTN: When upgrading from an older version, it is best to first delete the SteamVR folder in your project, and then import the package. You may also want to delete any 'openvr_api' files in your Plugins folder and its subfolders before importing the new package. The SteamVR SDK allows developers to target a single interface that will work with all major virtual reality headsets from seated to room scale experiences. Additionally, it provides access to tracked controllers, chaperoning, render models for tracked devices, and includes examples for using Unity's various UI systems in VR. SteamVR's compositor allows you to preview your content in VR using Unity's play mode, while leaving the normal game window to act as your companion screen on the main monitor. Supports DX11 on Windows 7 and up (OpenGL on Mac and Linux coming soon) Requires installing the SteamVR runtime via Steam to use (under Tools).
