一种虚拟漫游场景中建立可交互活动模型的方法

A Method to Constitute Active and Interactive Modelsin VR Roaming Scenes

提出了一种在虚拟漫游场景中添加可交互活动模型的新方法.该方法的核心是将场景内活动模型的每一步行动与随机数发生器产生的随机数联系起来.活动模型根据内部结构和信息分为几类,同一类的模型可以拥有不同的外形.通过合理地复用这几类模型,以较小的数据开销得到丰富的视觉效果.在基于普通PC的漫游系统上应用此方法,用户与系统的交互信息量增加了400%,证明此方法可有效增强场景沉浸感,提高系统交互性.

A new method is put forward in this paper to set up movable interactive models in the roaming scenes. The core element is linking up every movement of the movable model of the scene with the random number generated by the random number generator. The movable models are categorized by internal structure and information, the models of the same category can have different skins. We get abundant visal effect at a low cost by reasonable reusing of the models. The interaction information increase 400% after we apply this method to ordinary roaming systems, so the method is proved effective in boosting up the immersion of the scenes and improving the interaction of the system.
