摘要
混合现实应用开发中,当手势在真实物理空间中操作全息物体进行空间变换时,需要实现缓动、平滑过渡的功能。依据非线性插值原理,利用Unity3D游戏引擎封装的属性和方法,构建出应用于Holo Lens软件开发的插值器类。该类中定义了与插值相关字段和属性,并依据插值原理实现针对空间变换的非线性插值计算方法,最终形成插值器类。经测试使用该插值器类使得全息物体在真实物理环境中进行位置、姿态以及大小的空间变换时,可以实现平滑缓动过渡,从而减少眩晕感,提升用户体验。目前已经被作为基础工具类应用于混合现实应用开发中。
In order to achieve smooth transition in the mixed reality experience when virtual objects are transformed by gestures or voice controlling in the physical world. We use the API from UWP and Unity3 D to construct interpolator which is applied to software application development for Microsoft mixed reality platform Holo Lens,making virtual objects get smooth transition effect if the position,attitude and size change in a real environment. By experiment, this interpolator can effectively improve the experience and visual effects of space information transformation of virtual objects in the real environment with the gesture and speech input of Holo Lens. It has been applied to the development of holographic applications.
