Unity3D game engine is an integrated development tool for producing other interactive contents
such as video game, architectural visualization, real-time 3D animation. Its editor runs on Window,
Mac OS X, so it could make games as the platforms of Window, Mac, Wii, iPad, and iPhone. It could
also produce web browser game that uses unity web player plug-in. This is a similar form of flash, and
it is designed so that flash user could easily adapt even with cross domain security policy and scripting.
