摘　　要：虚拟网络教室在增强在线教学的灵活性、可交互性等方面具有重要的作用,但传统虚拟网络教室以网络教学资源共享平台和以视音频为核心的在线网络教学平台为主,所创建的虚拟学习环境缺乏真实感、师生之间的交流与互动比较单一。根据云计算的特点和真实感虚拟学习情景构建的要求,利用开源云计算平台OpenStack和分布式虚拟现实开发了一种支持用户管理、真实感3D虚拟角色自动生成、在线课堂教学、在线答疑等的真实感3D虚拟网络教室,并研究其开发与实现过程,最后以《大学英语》在线课堂教学为例分析该3D虚拟网络教室的稳定性和可用性,实验证明该系统能够有效增强虚拟学习环境的真实性和交互性。Virtual classroom can strengthen the flexibility and interaction of online teaching, but the traditional virtual classrooms are network teaching resources sharing platform and online network teaching platform based on audio, the virtual learning environment lacks reality and interaction between teachers and students is too single. According to the characteristics of cloud computing and the requirements of constructing realistic virtual learning environment, a realistic 3D virtual classroom is designed that supports user management, realistic 3D virtual character automatically generate, online classroom teaching, online FAQ using cloud computing and distributed virtual reality technology, and research the key technology and its development. Finally, take college English as an example, analyzed the stability and usability of the 3D virtual classroom, the experiment shows that the system can effectively enhance the authenticity and interactivity of virtual learning environment.
