力反馈技术在虚拟绘制中的实现与应用

Implementation and Application of Force Feedback Technology in Virtual Painting

针对目前国内中国书画计算机仿真中缺少触觉力反馈控制功能的问题,提出将力反馈技术引入虚拟绘制中,主要介绍了其实现的步骤和仿真系统的结构,分析了采用的弹簧-振子力学仿真模型,并描述了虚拟绘制过程中虚拟毛笔挤压宣纸模型的压力和在纸张表面上的摩擦力的实现方法,同时将Phantom Desktop力反馈设备应用到已开发的虚拟绘制系统中。结果表明:该力反馈技术能有效增强绘制过程的真实感,并且满足交互过程对实时性的要求。

In order to enhance the force / tactile sense and the controlling functionality for simulating of chinese painting and calligraphy,force feedback technology was introduced into the virtual painting system. Its implementation and its simulation structure were briefly discussed,its mass-sping simulation model was analyzed,and the implementation methods of pressure in virtual brush extruding rice paper model and friction on rice paper surface were described. Meanwhile,the force feedback device Phantom Desktop was applied to the virtual painting system. The experimental results show that force feedback technology can effectively enhance realistic to users and satisfy the requirement of real-time interactive.
