Interactive Projection Based Game Development Platform

Augmented Reality (AR) allows the user to see the real world, with virtual objects superimposed upon or composited with the real world. Therefore, AR enhances a user's perception of and interaction with the real world. Now it has become an important research field in Virtual Reality and next generation of human. Projector-Camera based interactive projection system is a important field in augmented reality.In this paper, we design and realize a game development platform under interactive projection environment. It describes the platform's design and realize method. The features of this platform are highly modular, strong physics and graphics features ,support Mosaic, Synchronization and quick efficient game title development under interactive projection environment.This paper discuss focused on the following aspects :Platform architecture. The whole platform is divide into two layers: platform support layer and platform interface layer. Platform support layer includes calibration, motion track, synchronization, dispatch module. Platform interface layer includes graphics, platform main interface, physics, sound, video module. Calibration module make multi-projection concatenation. Motion track module track human interaction info. Synchronization module is used for multi-computer synchronization. Dispatch module is used for mod creating, releasing and changing. Graphics module is used for rendering. Physics module encapsulate open source engine bullet, it connects graphics engine Ogre and Bullet. Sound and video module support common sound and video playing task. When using this platform developing title, it need not to use platform layer modules directly. Thus need not to consider synchronization and calibration problem. This greatly improve title developing speed.Next we will introduce wave simulation sub module, we implemented common environment wave. We also simulate interaction between water and sphere using wave particle principle.
