Research and development of scene rendering in interactive virtual exhibition

This paper analyzes the Virtual Engine platform "Virtools" and the theory of Multi-touch technology, explores the way to merge the behavior interactive module of Virtools and Multi-touch control mechanism, and proposes a resolution which integrates the virtual scene rendering and touch interaction. By creating the virtual scene of Dunhuang Mogao Grotto and combining the interactive advantage of Virtools when manipulating the 3D objects, the proposed system has created an immersive sensation of entering into the real environment. During the tour, the system will bring strong interests in Historical sites' culture to its visitors. Implementation of the proposed system show that the researches on the virtual scene rendering and the integration of interactive technologies have achieved the desired effect.
