Unity3D 作为一个功能强大且具有良好的跨平台特性的三维引擎,在构建交互式的虚拟场景方面具有极大的应用空间,将其应用于教学,具有重要的现实意义.鉴于此,通过对减速器的基本构造和结构进行分析,在研究Unity3D构建三维交互式虚拟场景的方法和关键技术的基础上,以几类典型的减速器为例,构建了减速器虚拟拆装实验,可发布为多平台运行,其中,基于移动平台独立运行的APP,无需网络支持,更加便捷,应用更为广泛,在结构认知、产品拆装、课程设计等教学和实践环节中取得了良好的教学效果.%Unity3D, as a powerful and good cross-platform 3D engine, has great application space in building interactive virtual scenes, and it is of great practical significance for teaching. In view of this, by analyzing the basic structure of the reducer, and on the basis of studying the method and key technology of constructing three-dimensional interactive virtual scenes with Unity3D, taking some kinds of reduces as examples, a reducer virtual disassembly and assembly experiment is constructed, which can run based on many platforms. And APP which independently runs based on mobile platform and no needs web support, is more convince and available, has achieved good teaching effect in application, such as structure cognition, product disassembly, curriculum design, etc.
