虚拟实验软件的建模方法与实现技术

虚拟现实型实验教学软件从真实实验抽象出场景、仪器对象及元器件对象，采用面向对象方法对它们进行数值建模与图像建模，完成物理实验的虚拟、本文总结了该软件开发过程中的各种仿真建模方法和实现技术，包括数学模，型的建立、静态和动态三维图像模型的建立、数学模型与图像模型的协调工作等。该虚拟物理实验实现了可设计性、操作的任意性和具有真实感的交互功能，使学生能像操作真实实验一样操作它，产生浓厚的兴趣，达到良好的教学效果。

Model-building Methods and the Realization Technologies in the Virtual Experimental Software

The experimental teaching software simulates physical experiments by abstracting scenes, instrument objects and element objects from them, and building numerical and graphic models for them with object-oriented method. This paper has summarized kinds of model-building methods and realization technologies of the software, such as the establishment of mathematical models, static and dynamic 3-D image models, the cooperation of the models, etc. The virtual physics experimental software achieves excellent performance in designability, arbitrariness of operation and interaction with sense of reality. It makes students operate it with great interest just like doing real experiments and gains good effect in physical experiment teaching.
