The Design And Implementation Of Virtual Experiment Of The Chemical Liquid And Metal Reaction Based On OpenGL

Virtual Laboratory, as a research focus in the educational field, provides a new idea for experiment-teaching reform and it has the advantages of being economical, safe, space-time unrestricted, and integrated teaching etc, compared with traditional experiments. For chemistry teaching in middle schools, the most important application of information technology is the introduction of virtual chemical laboratory, by which students can understand more deeply and teachers can demonstrate chemical knowledge and each of the chemical experiment processes more clearly.At present, although the study of the virtual learning environment has some progress, it still has some problems. One of the most prominent questions is that most of the virtual learning environment is designed by two-dimensional graphic technology, which have not reflected the true meaning of virtual reality, and been inadequate on the performance of space expression. That is why, this paper attempts to develop a 3D virtual technology-based virtual chemical experiment environment.This article outlines the technology of virtual experiments; virtual experiments development status at home and abroad, introduces key technology,some correlative algorithm,the development environment for simulating chemistry experiments. Studied the characteristics of chemical reactions with the liquid and metal, proposed a method of simulation through simulation reaction processes and key experimental phenomena to implement virtual experiment. Then focuses on the technology for simulate key phenomena such as collision detection, particle systems; finally implement the reaction of sodium and water virtual experiments.
