虚拟实验教学可视化设计关键技术研究

Research on key technologies in visual design virtual experimental teaching

VRML是一种虚拟现实三维立体网络程序语言,可以构造虚拟场景并实现用户与虚拟场景的互动,能解决实验教学中的诸多问题.文中着重对虚拟实验教学可视化设计的场景优化和X3D动态交互过程两个关键技术进行分析,并给出一个典型的应用案例.实践证明,基于VRML的虚拟现实技术是一项新兴的技术,在实验教学上有着广阔的应用前景.尽管这种虚拟实验技术不可能完全取代实际的实验操作,但鉴于实验教学的特点以及它具有的时空随意性、教学交互性、学习环境真实性等特点,让老师的实验教学如虎添翼,能真正满足教育教学的需求.

VRMI is a virtual reality three-dimensional network programming language. It can construct a virtual scene and achieve the user interaction with the virtual scenes, it also can solve lots of experimental teaching questiones. This article focused on visualization design optimization of virtual experiment teaching, and gave a typical application case. Though this virtual experiment technology can not completely replace the actual experimental operations, it has a spatial and temporal randomness, interactive teaching, characteristics of the authenticity of the learning environment. In all, it can really meet the needs of education and teaching.
