提出一种基于Leap Motion的对小鼠卵巢进行切割的实验模拟方法。精确采集小鼠各主要器官的真实形态数据;然后对这些数据特征进行深入分析,并利用3ds MAX进行精细建模;将三维模型导入Unity3D中,搭建虚拟实验环境并创建Leap Motion接口;通过基于碰撞点形成平面的切割算法来实现对小鼠卵巢的切割模拟,并通过基于运动学的形变算法实现形变模拟。该切割算法通过虚拟器械与模型网格的碰撞,以碰撞点和摄像机形成的平面对模型网格进行切割和网格重建。实验结果表明:该算法能够真实、有效地对小鼠卵巢模型的切割进行模拟,同时能够真实再现现实实验的操作体验。

A cutting algorithm was proposed for Mouse＇s ovary model based Leap Motion. The realistic data of the main mouse organs were collected. These data were deeply analyzed. The models of mouse and organs were imported into Unity3 D to create a virtual environment and an interface between Leap Motion and Unity3 D. It realized the cutting on mouse＇s ovary model through a cutting algorithm which created a plane formed by the collision points and the camera, and it realized the deformation of the mouse＇s ovary model through a deformation algorithm based kinematic formula. The results show that the cutting algorithm can simulate the cutting experiment on mouse＇s ovary effectively and make the people have a realistic experience.
