摘要
虚拟现实领域中,人们对三维花卉植物可视化及交互感的需求越来越强烈,而触摸力度引起的植物受力形变过程又无法采用现有的植物运动形变方法进行模拟,因为现有方法造成了模拟失真,交互感差。根据植物整株交互需求或单一叶片受力情况,分析不同方式的运动反馈模拟方法,先判断受力情况,根据动力学原理模拟整株受力,根据触摸屏获取数据,结合叶脉骨架旋转模型算法计算出单一叶片因受力而发生的形变,不需手动输入参数,就能模拟不同力度触摸造成的叶片形变。本方法应用在移动平台后,真实感和帧速率情况良好,可视化和交互感大大提升,并可推广到同类结构的物体模拟。
Highly interactive 3Dvisualization of flower plants on mobile platform has become an important requirements of plant researchers,garden designers etc.However,simulations of specific deformation process of the whole plant or single blade under different touching intensity are not available through existing methods,which causes the distortion simulation and poor interactive sense.This paper analyzed the interaction requirements of whole plant or force conditions of single blade,and studied several methods for motion-feedback simulation.The force conditions are determined first.Then,the deformation of the whole plant is simulated according to dynamics theory,and the deformation of single blade is calculated according to the data from touch screen and rotation-model of vein skeletons.Deformation processes under different touching intensity are simulated without inputting parameters manually.With this method applied on the mobile platform,satisfactory realism and frame rates are obtained,visualization and interaction are promoted greatly.Beside,the method can be extended to the similar structure of the object simulation.
