| With the development of mobile terminal technology and the increase of demand for small garden design,3D flower plants display and interactive system on mobile platform has become an important research need of plants, garden design and other fields. For mobile platform applications, available and easy to use is very important. One of the key points of it is friendly, real and effective user feedback. In the3D flower plants display and interactive systems, user experience is improved by the timely and realistic feedback of flowers after dragged or touched. However, there are some limitations of existing3D deformation of flower plants simulation methods more or less. That do not apply to interaction systems. On the other hand, in order to meet user needs while reducing development costs, cross-platform applications have become hot.In this paper, based on the characteristics of the mobile platform, a cross-platform3D display and interactive system of flower plants was designed and implemented. First, for the interface design, interaction design and user feedback design, interactive approach applicable to3D display of flowers and simple garden design was designed. This paper 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. Finally, compatibility issues between mobile platforms was resolved. With this method applied on mobile platform, satisfactory realism and frame rates are obtained. |
