沉浸式VR教学系统“未奥”

Immersion VR Teaching System"VisAll"

科学可视化教学在全球很多大学已开设,其中体数据可视化有助于理解数据中包含的内部信息,如几何结构和特征等,但是其原理抽象难懂。基于GPU的CUDA框架,利用传递函数、立体显示、手势交互等技术,建立沉浸式“未奥”教学系统,帮助学生理解传递函数、体绘制、沉浸感、手势交互以及虚拟现实等概念。通过评价实验可以得出,新开发的系统是辅助科学可视化教学的有力工具,可作为VR教学模版扩展到科学可视化其余教学内容或其它教学课程。

Scientific visualization course has been taught in many universities around world.Among them,volume visualization helps students to observe the internal information hidden in the data intuitively such as geometry structures,features and etc.,however,its abstract principle is difficult to understand.This paper describes an immersive visualization system called VisAll based on the CUDA of GPU which assists students to understand the concepts of transfer functions,volume rendering,immersion,hand gestures interaction,virtual reality and etc.The experiment and evaluation show that it is a powerful tool to assist the scientific visualization course,and can be extended to other contents of the course or other courses.
