Graph Based Pre-Rendered Approach to Virtual Reality for Cultural Heritage Applications

摘要: The term Virtual Reality usually refers to the promise of a visually believable interactive experience in 3D world, typically visualized through real-time rendering polygonal textured models. In this paper we present different approach fruition rich virtual environments populated by highly realistic computer generated characters, featuring state art lighting, shading and animation techniques. proposed framework does not rely on but high resolution stereo pre-rendering instead. A graph, whose nodes represent pre-rendered audio-video clips available for given context, is visited during navigation interaction, allowing user enjoy experience. This methodology, though limiting action freedom could be effectively used VR applications fields such as Edutainment Cultural Heritage. We show applied exploration digitally reconstructed archaeological site Moregine (Pompei) guided one its last inhabitants.
