移动平台上高交互感的三维花卉植物可视化已成为植物研究、园艺设计等领域的重要需求，但现有植物运动形变方法还不能根据触摸力度对整株花卉植物或单一叶片的受力进行不同的形变过程模拟。为此，提出一种改进的三维花卉植物触摸反馈可视化模拟方法。根据植物整株交互需求或单一叶片受力情况，研究不同方式的触摸反馈模拟方法。在模拟触摸反馈时，整株受力应用动力学原理，抽象为杆件模型并计算形变结果。单一叶片受力时，根据触摸屏获取数据，并结合叶脉骨架旋转模型算法，模拟不同力度触摸造成的叶片形变，过程中无需手动输入参数。仿真结果表明，该方法应用于移动平台后，帧速率稳定，具有较高的真实感。

Highly interactive visualization of 3 D 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 via existing methods. Therefore, this paper proposes a visual simulation method of 3D flower plants touch feedback on mobile platform, presents analysis of the interaction requirements of whole plant or force conditions of single blade,and studies several methods for touch feedback simulation. In the simulation, the method is divided into two parts. The deformation of the whole plant is simulated according to dynamics theory, the deformation of single blade is calculated according to data from touch screen and rotation model of vein skeletons. Deformation processes under different touching intensity are simulated without inputting parameters manually. Simulation results show that this method can be applied on mobile platform,satisfactory realism and frame rates are obtained.
