基于三维虚拟技术的网页动画特效系统

Web animation special effect system based on 3D virtual technology

针对网页动画特效逼真度不高等问题,研究了一种基于三维虚拟技术的网页动画特效系统。该方法在数据访问层利用FLASH存储卡,存储动画特效数据;利用动画特效逻辑层调用数据访问层存储数据,粒子模块使用粒子理论模拟动画画面,为动画添加特效,运动模块利用VR动画交互节点设计动画节点坐标,实现动画运动特效处理;通过系统表示层为用户呈现特效制作成果。实验结果表明:该系统可有效实现动画的雨、雪、烟花等特效制作,且逼真度高;兼容度平均超过90%;特效制作响应时间均未超过1.4s,系统运行流畅。

To tackle the low fidelity of Web animation effects,a web animation effects system based on 3D virtual technology is studied.In the data access layer,flash memory card is used to store animation effect data.The animation effect logic layer is used to call the data access layer to store data.The particle module uses the particle theory to simulate the animation picture and add special effects to the animation.The motion module uses the VR animation interaction node to design the animation node coordinates to realize the animation motion effect processing;The special effect production results are presented to users through the system presentation layer.The experimental results show that the system can effectively realize the special effects of rain,snow and fireworks,and has high fidelity;The average compatibility exceeds 90%;The response time of special effect production does not exceed 1.4s,and the system runs smoothly.
