Unity Pro是一个非常强大的工具，可以让我们创建自己的可视化游戏，另外在互联网上我们可以找到大量的视频课程，这些课程明显有助于我们一步一步地执行所有必要的操作。
Unity支持Boo语言，所以喜欢编程的人员，可以最大化的利用这些来脑洞大开，现在VR虚拟场景技术越来越受到大家的欢迎，那么Unity是一个不可多得的VR技术平台实现者。
Unity Pro 2017.4.0f1 更新日志
Improvements
2D: Change Outline and Physics Shape module behaviour in Sprite Editor Window. The module will only show outlines only when user has customised it.
2D: TextureImporter Inspector has an option to enable default Physics Shape for Sprites
Linux: Improved filesystem performance to handle large cache sizes.
XR: Improved background rendering performance in ARCore by eliminating an unnecessary OpenGL state reset.
XR: Updated Oculus to version 1.22.
Changes
Asset Import: Adjusted messaging around Substance Designer import removal.
XR: Android builds that enable ARCore no longer fail when the minimum Android SDK is less than 24.
XR: Standalone UWP applications targeting Windows Mixed Reality will now cause the OS to notify the user if the Mixed Reality components are not installed or a headset is not connected, rather than silently falling back to non-VR desktop mode.
