利用Three.js技术实现物理实验三维仿真

Using Three.js Technology to Realize 3D Simulation of Physical Experiments

虚拟仿真实验教学能弥补传统物理实验的不足,现有物理实验仿真软件大都是二维的,教学效果有限。采用Three.js 3D技术,以“撒克逊碗下沉实验”为例,通过构建三维模型突破平面限制,实现一个立体的、在线的交互式虚拟仿真系统:通过对实验器材和过程三维建模,实现立体仿真,设计了4种实验探究变量间关系,虚拟教师提升可观察性,视频、语音增加了趣味性。应用实践表明,该系统能大大提高教学效果。

Virtual simulation experiment teaching can make up for the deficiency of traditional physics experiment,but the existing physics experiment simulation software is mostly two-dimensional,and the teaching effect is limited.This system adopts Three.js 3D technology,takes“Saxon bowl sinking experiment”as an example,breaks through the plane limitation by constructing a three-dimensional model,and realizes a three-dimensional,online interactive virtual simulation system:Through the three-dimensional modeling of experimental equipment and process,three-dimensional simulation is realized,and four kinds of experiments are designed to explore the relationship between variables.Virtual teachers improves the observability,and video and voice increased the interest.The application practice shows that this system can greatly improve the teaching effect.
