Abstract
To facilitate the independent learning and safety experiments, the network virtual laboratory is one of the hot spots of the current research. After analyzing advantages and disadvantages of the current virtual laboratory, this paper introduces the web-based and self-adaptive virtual laboratory platform, with a three-tier structure of the B/S mode. And the platform has two groups of users: teachers and students. Teachers can customize experiments which can be performed by students in the platform. The formation of the experiment consists of two parts: the equipment based on object-oriented ideas and used geometric modeling technology, which has more realistic effect, and achieves real-time rendering; And environmental background using cylindrical panoramic technology, which has photo effects, and loading faster. These two parts is combined through photography geometric principles. The experiment proved that in this virtual laboratory platform, the experiment is loading fast, have stronger sense of immersion and effectively improve the students' network learning efficiency.
