总结：
挺有意思的。
Tiny就是一个unity公司出的一个unity3d 做h5的插件
Tiny目前看支持2d。和unity集成程序不是大家想象中的完美，完全就是两套体系。比如工程项目建立和读取。
巴拉巴拉一堆不完美的东西。国内三大引擎踩过的坑他们都得踩。想技术玩玩的就愉快的采坑好了。想做项目赚钱的老板们别碰 。老老实实三大引擎。
unity3d官方确定不支持3d，然后要明年才有可能支持3d

Expect to start seeing 3D next year. We are not yet ready to share anything more detailed at this time. Largely because we want to make sure the foundation is solid and doing what it needs to do. With that said, everything has been build knowing 3D support will be added.
