[Abstract]:This subject aims at the present situation of university teaching, especially science and engineering teaching, according to the plan of national development practice teaching, combined with pedagogy theory knowledge and VR teaching idea. Using the virtual reality development platform Unity3D, 3D modeling software SolidWorks3D Max, image processing software PhotoShop and other computer software. Based on the common bicycle in life, a set of mechanical manufacturing software is developed, which is suitable for the learning and application of mechanical subject. In order to achieve the learning effect of the combination of theoretical knowledge and practice. The contents of this research include the following aspects: 1). Theoretical basis and technical support for the development of teaching cases: the theoretical basis is the cognitive learning theory and the constructive learning theory in the teaching field; Technical support mainly includes the choice of virtual reality development software, 3D modeling technology, computer programming language. The key techniques of the teaching case include the optimization of scene model, the making of animation and the realization of visual effect rendering. The optimization of scene model includes modeling and optimization scheme, model optimization and detail level; Animation production involves key frame technology and particle system; The realization of visual effect rendering mainly includes 50) 畏? ? ? ? Medium illumination, mapping, reflection, diffuse reflection, etc. 40) the main implementation from? 38? Build the interface and? 40) setting up the standard two aspects narration; The realization of mechanical motion is described from the angle of graphics and programming. Code specification mainly from the script storage location and script naming specification from two angles: the specific implementation of teaching cases: combined with the development of theoretical basis and technical support, under the support of the teaching case framework. With the help of key technology, the realization process of teaching case and the process of part manufacturing analysis are discussed comprehensively. Under the support of teaching case framework, the realization of teaching case is mainly discussed from three aspects, namely, model parts. Manufacturing process and integral assembly; The manufacturing process of the parts describes the overall development flow process by selecting the machining of the hub shaft, the chain plate and the frame of the typical parts as a case, in which the processing and development process of the central shaft is introduced in detail.
