View source for Multi-user virtual reality on mobile phones

==Project Overview==
* This project allows 2 users use 2 android phones to connect to each other by TCP, then they can navigate and interact to each other in a virtual world. Both users use first-person-view to view the world, they can change their viewing direction by rotating the phone if the phone has gyroscope. 
* Explanation of the picture: The triangle in the left phone represents the orientation and position of right phone.

==Status==

===Implemented===
* TCP connection between 2 phones and periodically update the information of the world( including the status of dynamic objects and status of the other user)  
* Change viewing direction by gyroscope
* Built by OpenSceneGraph for android phones.
* Users can do some actions on dynamic objects (such as open a door) and the other user can see the change. 

===To-do===

* Allow user to create geometries in the world and other users can see the created geometries 
* Maybe try to use a PC as server to allow more than 2 users to connect, the loading might be too heavy for one phone to be a network server for many clients.
* Model modification support
