Research On Three Dimensional Modeling Technology For Virtual Experiment

Along with the distance learning and the virtual reality technology's development, the virtual laboratory's development based on network and the correlation questions become the current distance learning research focus. Many disciplines need to establish the massive experiment curriculum to raise student's practical ability in distance learning's field teaching. The virtual reality technology's universal application enables the network educational model, especially the network experiment educational model, to obtain the consummation in the education. Therefore founding the virtual experiment environment by full use of virtual reality technology to maximized study resources and optimized study effect appears the important. Effective establishment of virtual environment based on Web needs to consider many aspects. In the virtual environment each kind of model's foundation is the foundation and the important factor of the entire virtual reality system establishment. What kind of modelling tool to be used and how to establish the virtual environment to be suitable for the network study effectively and quickly to bring long-distance learner the joyful and lifelike learning experience is the successful key to the virtual experiment environment establishes. And takes the virtual reality technology the core and the soul, the three dimensional modeling technology is the only entrance that learners access to the marvelous virtual interactive world. It can be said that both virtual model accuracy and simulation scene real solidity in experiment directly decided the entire virtual reality system founds success or failure. This article has discussed the correlation theories and practice in developing virtual experiment based on the Web from contrasting traditional teaching and virtual experiment teaching, virtual reality technology own merit and shortcoming, in each related domain application condition and prospects for development. Focuses in the experiment teaching of the non-immersion virtual reality technology the application and union of vision performance and educational technique related question, the article has studied the correlation theories and the practice in developing virtual experiment thoroughly. Through define and classify Web3D technology that applies in the virtual experiment performance history, this article further elaborates related question about how to choose the third party modelling tool in developing virtual experiment's by using Web3D technology. And aims at the current situation that the domestic developing virtual experiment and virtual laboratory have generally the virtualization deficient or in the performance history uses the unreasonable modeling technology, this article determined that the research goal was using popular the three dimensional modeling technology to solve the questions that exist in virtual experiment and relate to interactive immersion feeling, trying to provide more lifelike experience opportunity through establishing virtual experiment environment for the learners. And the learners may realize understanding and the observation of experiment instruments through a series of virtual interactive operations, may obtain the scientific and the effective experimental result and the conclusion, and may obtain the knowledge skills and the emotion experiences similar to real experiment. The virtual reality technology provides the immersion feeling and virtual instruments interactive operation experience, the teaching can achieve the ideal experiment effect under lacking of equipment condition to be possible. The body divides into five parts.The first part is an introduction, mainly elaborated that this research's background, the research question's determination and the prime task which does regarding the research question, and performs the brief statement to this article content structure. This part introduced the process that this research question proposes, and had determined this research's primary coverage is the three dimensional modeling technology in the network hypothesized experiment's applied research, and inspected this thesis present research situation and so on.The second part has discussed correlation theories and the practice about VR technology and the virtual experiment modelling. In summarizes in various experts research results foundation, the article had determined the virtual reality technology applies in the experiment teaching theory basis, based on massive literature summary of applying the three dimensional modeling technology to developed virtual experiment, proposed the application development conception about the three dimensional modeling technology in the development virtual experiment.The third part discussed the related issue to three dimensional modelling principles and the modeling technology chooses. This part has carried on the concrete and comprehensive contrast to the merits and demerits of three dimensional modeling technology commonly used in developing virtual experiment. And it has made the consideration and the analysis to the concrete reason of using 3dsmax to carry on the virtual scene modelling. The part proposed the principle needs to follow and the matters needing attention in modelling process, and has made the detailed elaboration to the modelling tool's function which must undertake in the developing virtual experiment flow.The fourth part takes"Flatness measurement"virtual experiment's development as an example, further launches the practice research on applying three dimensional modeling technology in the virtual experiment development. And the part proposed the general flow, the model visual performance, the model movement establishment and the frequently asked questions solution in using 3dsmax to carry on the virtual reality system three-dimensional model construction.The fifth part summarized the prime task and the achievement of this article and the prospects for further study. This part broadly elaborated that the article mainly discusses the realization of three-dimensional model in virtual experiment through designing and developing examples to solve some practical problems in virtual experiment and improve the visual immersion effect of the virtual product and the developing quality and speed.This article takes the correlative theories with visual design and visual transmission and the practical application of virtual reality technology in education as the theory and the practice foundation. By analyzing several common Web3D modeling technology which are the foundation and the core of developing virtual experiment and even virtual reality system and the advantages and disadvantages of each application, the thesis summarized the construction principles of virtual model and the reason of using 3dsmax to take the modelling tool. Based on more representative of the engineering experiment "Flatness Measurement" virtual experiment virtual object modeling as an example, this research to appear general principles, common methods and the approaches in the development of virtual experiments using 3dsmax modeling to strengthen the learner's immersion feeling and attract their attention and improve learners poor self-discipline when carries on the long-distance study and achieve the purpose of learning.Research on this topic can not only relieve condition pressure for the traditional experiment teaching and provide the effective supplement, and can play a certain role in the guidelines to the development of virtual experiment and virtual laboratory constructed and optimized virtual model. Moreover, the author hoped that the present paper findings can play certain role in alleviating and improving the present situation which the domestic experiment teaching software and hardware construction and the equipment condition are insufficient, then through builds the experiment teaching environment which one kind optimizes to consummate the hypothesized time gradually the experiment teaching system.
