Design And Implementation Of Three Dimensional Chemistry Molecule Lab Based On Virtual Reality Technology

The molecular structure in the high school chemistry teaching is an essential content, knows the molecular structure regarding the student, thus further understood that molecular the electronic formula, the chemical formula, then the understanding chemical reaction equation has the extremely vital role. At present in the molecular teaching, the teacher uses the demonstration picture or the model way. Has designed the demonstration member model, the molecular synthesis and the decomposition animation demonstration, the build member model, the simulation chemical reaction change phenomenon, typical molecular demonstration ,the chemical equation animation demonstration in this system and so on several parts, causes the learner to control the animation demonstration which through oneself the molecular model, choice chemical experiment instrument and chemical experiment drugs,the observation chemical reaction change phenomenon, the molecular synthesis decompose, enabled the learner relates under the hypothesized environment from the macroscopic chemical reaction phenomenon and chemistry molecular formula animation demonstration and the microscopic chemistry member synthesis and the decomposition, saved the chemical reaction process time, has avoided the student the danger which operated at the experiment, simultaneously, macroscopic and microscopic will relate, causes the student to study the content Has a more profound understanding.A designing model and implementing method of chemistry molecule lab based on virtual reality technology is Realizated, which used virtools platform. The structure display of virtual chemistry molecule (VCM) is implemented by using modeling technology. The dynamic synthesis and decomposition of VCM is provided in the system, which adopted animation technology. And unifies closely with the middle school chemistry teaching material, by the student independent choice experiment instrument and the experiment drugs, the modelling process, and with three dimensional has vividly demonstrated the entire experiment process and the experiment phenomenon,Expert system design methods and VSL script language technology is used to solve the problem of VCM assembly and intelligent evaluation, which makes the system functional and usable. The system for users is more powerful by implementing the simulating chemistry molecule that has not been provided by former work, and overcomes the problems of molecule teaching and experiment.This article in this system performance history, has mainly done the following several aspect work:â‘ Realizated on the 3dmax and virtools three dimensional hypothesized molecular laboratory architecture, elaborated functional module and the way in detailâ‘¡Realizated carries on the management to many scenes the methodâ‘¢Realizated the construction array information and so on three-dimensional model which, store path involves to the system data processing methods.
