Researching For Modeling Technology Of Virtual Chemistry Experiment

Virtual reality is a very active area of technology in recent years. Currently, its application has been extensively involved in many areas, and brings huge economic benefits. Virtual experiments are based on the needs of modern education concepts generated, intelligent guidance and teaching and administration.Existing virtual chemistry experimental system mostly designed based on two-dimensional plane, three-dimensional virtual experimental study, just to stay in the framework of the exploration and implementation of key technical level, but the need for the appropriate platform on chemicals, laboratory instruments and the whole experiment about the modeling of the problem is not resolved and in-depth study. Virtual reality modeling technology is the basis for the establishment of virtual reality system, therefore, three-dimensional virtual chemistry experiments for the content of the modeling work associated with the very important research significance.This paper introduces the virtual reality modeling technology knowledge, and then to experiment to classify the content of the experimental test related equipment, chemicals from geometric modeling, physical modeling to the chemical analysis of the modeling process, and then sum up Virtual chemistry experiment platform for the effective support of equipment, medicine model. Other experiments need to model the contents (reaction conditions, the reaction equation, the reaction phenomena) also summarized its modeling. To the contents of the experimental model, various part of the corresponding modeling, on object-oriented thinking in accordance with the node-type division, and given its hierarchical tree structure diagram. In the chemical experiment, the reaction to the resultant of the quantitative control of the entire experiment, and the phenomena of chemical reactions were used the experimental process of modeling. In which the realization of Chemical reaction phenomenon be with the OSG particle system, therefore, a brief description of the OSG and its particle system is described in detail.On a typical example for each type of simulation, the results show that the play its due role, it makes the junior high school chemistry textbooks in all the experiments are a class of ownership, easy examples can be built along the lines of such simulation. The contents of the node-based divided on Chemical experimental model, be well sort out the correspondence between them. Gas, precipitation and other chemical reaction and a little reaction conditions such as light, heating control and the experimental nature of the process of taking the process modeling, the simulation also allows more flexible and lively experiment.
